Hey Scottie I was wondering if can help. I have a 2004 Cadillac SRX service theft like keeps coming on I've changed fuse and tried everything else I'm sorry I didn't think is a e c m problem
I love this guy.I love working on my own vehicle and investing in my own tools , classes for this stuff cost hundreds of dollars and when you work full-time makes it harder but this guy is giving what he knows for Free!!!God bless you sir!!
Scotty your awesome. you and Eric (car guy) have saved me thousands and allowed me to be self reliant and more importantly increased my knowledge and trouble shooting abilities. From an engineer your common sense rocks
I'm in Milwaukee. Mechanics are idiots up here. I would be willing to drive my 18 yr old baby down to TN. Runs but quite sure it is a computer problem. I had a dinky 1F audio capacitor on it between 2 amps. Thought a mechanic would see 14 V on it. Unhook it. Had it been a TX sized one I would have unhooked it first. It was a joke too small I have been shocked by 5F ones. Mistake! He just left it. He thought taking the huge fuse off the battery would be fine. No! It is not wired like that. I'm really pissed. Any USA Lightning ppl please help. Will start taking the dash apart wiring in switches for parts that are electrically shot. Radio. Windows. Cabin lights only work when the engine is off. The boost dropped down to 8 which makes me even madder. I dont want to break it. I know enough computer/physics things I can REALLY break it. That is not a brag. If I get frustrated enough it will not be good.
I was getting the dreaded Flashing D on my '05 Pilot two weeks ago and my OBD2 code reader came back with two faults...P0974 and P0980 which are electrical faults within the circuits of Shift Solenoids A & C. I did some troubleshooting and I was coming up empty but I replaced the original solenoids anyway(which tested OK) due to the age of the vehicle. I was getting frustrated and feared it could very well be a faulty PCM. Anyway, i saw this vid so I ran out and purchased a can of the CRC Electronics Cleaner and I sprayed it on all of spade terminals on the PCM and also the female connections on the wiring harness. VOILA!! No more faults.This vid and that $8 can of spray saved my bacon. Thanks Scotty!
2007 dodge ram 5.7 Throttlebody problem I change the throttlebody problem continue I I purchased the gasolin pedal the truck still giving the light for throttlebody or gas pedal please help the light come on on freeway or normal lDrive
Scotty ... thank you ... I asked my daughter how she and her husband knew how to fix their car and effortlessly replied youtube as if it were no big deal. Without realizing it, I thought ... hmmm she must be thinking to herself why I would even need to ask 😂. Like - doesn't everyone know that? 😂 As if there was never life before youtube. Since then , and out of necessity, I have been making as many repairs on my own and keeping local parts stores in biz for the past two years; while pretty much keeping it to myself that this car is nearly reaching 3,000 miles. It's the last thing I ever thought I would ever see myself doing. Your videos have been immensely helpful ... 🌟👍
having cps problems on my 7.3 powerstroke. all sorts of info on the internet to put you in a black hole. 2nd replacement I used the same cleaner to get some dialectic grease out of the connection as I was afraid I had put to much on during the 1st repair. seems to be working 35 m test run. then I see this. Scott you are the man. I bet this would fix all the problems on the Ford forums. thank you for all your videos and sharing your knowledge.
Scotty Kilmer is awesome, thank goodness for the internet or I would have never learned so much. Scotty... back when you first started working on cars, did you ever think you would be able to share your knowledge with the entire world so easily? I think we take the internet for granted, when just under 2 decades ago is was nonexistent.
I need your help car start then dies then i turn the ignition switch on and off then starts up but rpm can go higher when i press the gas peddle its make like a deep sound
Scotty, lol if I paid to move you to my town would you plz. 99% of the time I'm having vehicle issues, your videos r my go to.....n have helped more than you'll ever know man......your awesome man....
Nicely put video, Scotty. If the spray cleaner doesn't help to get the car started, feel free to contact our technicians to help you out with all your engine computer needs. And no, it doesn't cost a fortune. Ours start from just $48 per unit.
Eehhhhh...not to dissuade business from Flagship One, Inc. but please read their reviews and make a decision for yourself. I'm in a situation where these guys are all I have left to help get my car running. I'm waiting for my ECM to begin shipping (which it said it was to have started shipping within 24 to 48 hours of getting the tracking number. That was Friday, May 8th and it's now 5:12PM on Monday, May 11th. I'm going to wait until one more business day to see if it then moves and then call). While I'm happy for being emailed about delays or anything with the order, none of my sent emails have received a response and calling them takes three millennia to reach anyone.
@@TreyCFerg I did, I tried putting the ECM on myself but I think my battery was too dead to complete the full programming process. Not sure if it was necessary, but I purchased a second ECM and had a mechanic install it and it worked! Car still has a slew of other issues but the computer seems to be fine.
Great video I actually thought it was my pcm that was an issue on my 01 dodge intrepid and then I changed my camshaft position sensor and the engine light for the pcm went off thanks Scotty!
Hello Scotty. First, excuse my "rusty English" from the other side of the world. Hope you do not mind that I strongly suggest a more strict instruction when it comes to disconnect and reconnect car and boatbatteries. 1. ALWAYS disconnect the - (negative) terminal first before you touch the + (positiv terminal). 2. ALWAYS connect the + terminal first then the - terminal. Or earth if it is a car. The reason for this is that if you happend to tuch anything accidently with your tool nothing happens. (Also I recommend to loosen both connections if you cannot really safely put away the negativ connection.) Really enjoy to look at your videos. Best regards Lennart K* Myrhammar, Senior advisor (Boat mechanic for 45 years and Rescue Skipper) Stockholm, Sweden
I would have used throttle body. But, to check the egr valve, just remove it, and block the holes under it with a home made gasket. if the problem stops, then it's an egr problem, such as a sticking valve OR bad power feed to the valve.
Hi Scotty. I have been getting PO172 and 1073. I purchased a MAF and reset the computer. I then cleaned the throttle bottle and put back together. It starting running really bad and drove it for about an hour to clean it up but still almost stalls. The acceleration is better though. I then got code po401. The first thing I thought about was the egr valve. When I take the middle hose of the 3 hoses off the throttle body the one that is green the car starts running perfect. Back on rough
doesn't hurt anything, BUT I've had great luck with JB Weld Kwik in sealing such leaks, you clean the seam and put that all over and let it sit overnight
Contact spray works great on degreasing electronic clips in the engine. When valve covers loosens from vibration some oil leaks, or oil vapours from other components. This mixed with road dirt and debris kicked up in engine. A little preventive maintenance could go a long way to keeping that dreaded light on the dash.
I just bought a new computer for the car it should be here any day now I'm also going to go to Chrysler and get a cam positioning sensor from them maybe you are right I bought someone from AutoZone it look like the same part but you got a good point there
Saludos amigo ! Ive watch a couple of your videos and I can tell you got alot of mechanic knowledge under your belt !!! I hope you can help me out with a problem; I have a 2008 dodge charger, D starter got replace for sum failure cranking up, it seems like the positive cable was loose and it touched the ground from the engine,, it started a fire , we found the issue secured it ,, came back to live BUT after a while of driving the car it when into LIMP MODE now I don't have a clue of what could be the problem. Any of you old farts relate to this !?
Low fuel pressure is either a bad pump (if you didn't use a factory pump the cheaper ones often don't work), a restriction in the fuel filter or lines, OR a bad fuel pressure regulator. May be time to see a mechanic to analyze it
modern cars are SO complex, you'd need a machine as in my video "fixing modern cars using high level scan computers" to figure that one out. too much crap in em these days, drives me nuts too fixing them. I often cut all that crap off and run the AC with a toggle switch
I have a 1998 Dodge Avenger 2.0L MT base, everything is running normally, engine runs strong with no codes. Only when the car is cold started,the AC compressor clutch kicks in (when you start the Ac at dash button) and will stay on for about 1 minute then shuts off. I replaced the entire Ac system (piece by piece with new parts): ac compressor unit, drier unit, evaporator unit, expansion valve, switch thermistor at evaporator, Ac fuses, switch for Ac blower unit, all Ac lines L and H and other 2 Ac lines , the pressure switch in top of Ac drier, the Ac module and the Ac switch under dash and the control panel, fully recharged system with Freon and still doing the same thing. The engine temperature gauge is normal at half way and the engine is not running hot or having any issues, the fans work good, the only issue is AC stops blowing cold air Ac after 50 Sec. I figured that within a minute the system gets builds up pressure or hot somewhere and maybe something triggers the Ac clutch to shut off. Yesterday I just pulled the two main harness plugs going into the ECU unit and found (only at the upper plug) engine oil present there, I then started removing all the components under the ECU unit (the two other main harnesses that have a bunch of wires terminating into two white dead plugs and found a lot of oil in those plugs (soaked), I cleaned all with electronic cleaning spray (a lot off old oil white color came off from the two plugs). I also opened up the ecu unit (but it is waxed sealed on the inside) and cleaned the attached connectors and let it sit overnight to drip down the oil if any got inside the unit . I am thinking this should have been the issue but haven't plugged all back in together yet I am not a mechanic but this was my first car and last year I decided and put my mind to it to bring it back to life after it sat for 7 years. I did bring it back to it's glorious days (parts were very hard to find) but this Ac issue is the only hiccup that I can't get to find a solution for. Before, I even took the car to dodge dealership, they did an Ac system pressure check and all was good. I will plug all back together later today and I hope to God that the oil in the plugs was the issue tripping to stop the Ac compressor clutch after about 1 minute of starting the car.
Hey Scotty, I have a 94 C4 Corvette. While driving the car suddenly shuts off. I sometimes have to wait 3-5 min before trying to restart to get it to kick back over. I've noticed some electrical issues within the car like the door switches moving by themselves as well as door is open light constantly coming on. Could this just be a bad computer that can just simply be replaced. I know the fuel pump works through the computer and if it malfunctions, could cut off the fuel supply to the engine. Replaced Radiator, Water Pump, Opti Spark, Spark Plugs, Fuel Pump and Battery. I appreciate all the help cause I put thousands into my corvette already and it runs good otherwise.
So can you spray it on both the computer connectors as well is the plug-in part? Only saw you spray the computer connectors but in the video you said to clean both.
I am having this same problem with my 06 Nissan Altima 3.5 SE. P0340 camshaft sensor bank 1 circuitry- changed cam 1 and swapped barely connected harness. Brake & Battery light flickers on & off when i hit a bump, draining brand new agm battery, alternator whines, no power to alt, trans, or fuel pump😥 BUT 3 mechanics say its electrical. Thinking ecm, since the whole dash is on & off. This seems worth a try.
it's humid as heck here in Texas, that's plenty enough to corrode stuff, heck my guns are in an air conditioned house and they rust like made even then.
Usually it doesn't matter. However if you remove the positive first, be really careful while you're doing it not to accidentally touch the wrench to any adjacent metal. Good practice says to take the neg off first, for the following reason. If you remove the neg first, it won't matter if you accidentally touch metal, since the frame is also neg. Once the neg is off, accidentally touching pos to the frame is unlikely cause sparks.
Well their are times when it works just fine no jerks or long time engaging. Some times it work great and others it wont which makes me think it more of an electrical problem. Sometimes the truck smokes and the radio flickers on and off its just weird. But thanks for your help scotty and awesome helpful videos u make man.
Guardiantony31 check the ground black wire going from the negative battery terminal to the fender. Sometimes the bolt at the fender becomes loose and/or corroded. Clean and tighten.
98 Dodge Caravan pulled codes for the vapor canister purge solenoid and the BCM. Replaced the vapor canister purge solenoid and still doesn't crank. Please help me before I spend a lot of money.
So, I thought I may have accidently disturbed the old factory electric connection. The EGR vacuum regulator solenoid was given pulse voltage, so a good connection is probably vital. Now I want to thoroughly improve the connection at solenoid harness before other action. Do you have any advice on how to make a tight connection, or other advice to the above diagnose. I bought a bottle of Deox D100. Should I apply generously to the connector and harness? Thanks again in advance.
My Computer is in the engine compartment, why is it placed in a spot where it can get so hot and bake? By the way, my PCM only cost me a little over $200 and installed myself in a few minutes. Dodge wanted $1,600 to do the same. I am sure they would maybe have used a little more expensive brand new PCM but the refurbished I got has worked great for a year so far.
venturi carbs get better gas mileage but must be kept very clean. Piston carbs will run dirty on shitty gas but don't work as well and get worse gas mileage
Excellent Scotty- Got any good advice on electrical display issue with Dashboard of 2006 Chrysler 300c?! I checked Oil - Water. For over heating issues. I'll move onto dust on fuses next. I believe there maybe a "Touching" or no slack in wiring in the engine compartment. I'll wait for your review. - She's got a new Engine - different from the Factory one that DROWNED because of the Faulty Gas Sensor.
if you have the actual sending unit that runs the gauge and there is no wire on it, no, that's not normal. but realize they can put sending units on more than one place
I don't use dielectrical grease on computer connections, too many terminals and it can make connectors not tight as the connectors won't fit on right then
You can say that again. Thanks for responding quickly. Your videos have been invaluable as I've worked on all many systems recently. I sprayed out my PCM connectors today just as you demonstrate here. Hopefully it will finally solve my intermittent driveability issues. Fingers crossed as I'm out of ideas. My car does runs great 90% of the time now. How about a video on power windows problems for older 4th Gen (93-96) F-Bodys? Or one on how do you scan these 94s 12 pin flashable PCMs? Thanks!
Did it work? I’m having issues with my 2010 Mustang GT my scanner ain’t giving me a code for a bad PCM just a PO443 which I already replaced but the check engine light ain’t going away & scanner is till giving me the PO443. After seeing this video I’m hoping it just needs to be cleaned just like Scotty did 🤞
hey scotty i have a 00 mustang gt 4.6 and i catalyst where taken off and its currently running rich i have no check engine light what do you think that is?
i very much appricate your help with all the videos i have a 2004 Toyota prius .I watched your video on how to change the Hybrid synergy mechanical pump and i did replace with a new one . now the car will not even go into the acc mode to be able to start .I am doing a system reboot atm i am hoping the ECM will reset .if not could you help me locate the Ecm computer ? i will check that next i am used to Amerian made cars . gas conbustion engines i can rebuild a 350 blind folded , these Hybrids are another beast .
After reading this video, feel it maybe the ECM connector need clean? Do you have any opinion? By the way, thinking about buy a cheap ECM from eBay. Do you think the used ECM may need dealer re-program, even with the same make/model/engine? Thanks a lot.

yea, but it's humid as hell here in Texas, humidity ruins electronics.
I'm a new subscriber. Just wanted to say thanks for taking the time to make all your vids. Very informative and I'll keep watching and learning.
no idea, but akebono makes great pads and with them, any rotor can be used.
Thank you very much Scotty for the information.
another good tip, can you use anything on those connectors, like dielectric grease, to stop this from happening again?

modern cars are SO complex, you'd need a machine as in my video "fixing modern cars using high level scan computers" to figure that one out. too much crap in em these days, drives me nuts too fixing them. I often cut all that crap off and run the AC with a toggle switch
I have a 1998 Dodge Avenger 2.0L MT base, everything is running normally, engine runs strong with no codes.
Only when the car is cold started,the AC compressor clutch kicks in (when you start the Ac at dash button) and will stay on for about 1 minute then shuts off.
I replaced the entire Ac system (piece by piece with new parts): ac compressor unit, drier unit, evaporator unit, expansion valve, switch thermistor at evaporator, Ac fuses, switch for Ac blower unit, all Ac lines L and H and other 2 Ac lines , the pressure switch in top of Ac drier, the Ac module and the Ac switch under dash and the control panel, fully recharged system with Freon and still doing the same thing.
The engine temperature gauge is normal at half way and the engine is not running hot or having any issues, the fans work good, the only issue is AC stops blowing cold air Ac after 50 Sec.
I figured that within a minute the system gets builds up pressure or hot somewhere and maybe something triggers the Ac clutch to shut off.
Yesterday I just pulled the two main harness plugs going into the ECU unit and found (only at the upper plug) engine oil present there, I then started removing all the components under the ECU unit (the two other main harnesses that have a bunch of wires terminating into two white dead plugs and found a lot of oil in those plugs (soaked), I cleaned all with electronic cleaning spray (a lot off old oil white color came off from the two plugs). I also opened up the ecu unit (but it is waxed sealed on the inside) and cleaned the attached connectors and let it sit overnight to drip down the oil if any got inside the unit .
I am thinking this should have been the issue but haven't plugged all back in together yet
I am not a mechanic but this was my first car and last year I decided and put my mind to it to bring it back to life after it sat for 7 years.
I did bring it back to it's glorious days (parts were very hard to find) but this Ac issue is the only hiccup that I can't get to find a solution for.
Before, I even took the car to dodge dealership, they did an Ac system pressure check and all was good.
I will plug all back together later today and I hope to God that the oil in the plugs was the issue tripping to stop the Ac compressor clutch after about 1 minute of starting the car.
man your awesome ive learned alot from you man great to see this channel of yours
Hey Scotty, I have a 94 C4 Corvette. While driving the car suddenly shuts off. I sometimes have to wait 3-5 min before trying to restart to get it to kick back over. I've noticed some electrical issues within the car like the door switches moving by themselves as well as door is open light constantly coming on. Could this just be a bad computer that can just simply be replaced. I know the fuel pump works through the computer and if it malfunctions, could cut off the fuel supply to the engine. Replaced Radiator, Water Pump, Opti Spark, Spark Plugs, Fuel Pump and Battery. I appreciate all the help cause I put thousands into my corvette already and it runs good otherwise.
Do we spray the side that doesn’t have the pins as well or do we just wipe it clean without the spray?
both, the cleaner won't damage your connecter.
Man, I love your videos, simply genius! Thank you!
So can you spray it on both the computer connectors as well is the plug-in part? Only saw you spray the computer connectors but in the video you said to clean both.
I am having this same problem with my 06 Nissan Altima 3.5 SE. P0340 camshaft sensor bank 1 circuitry- changed cam 1 and swapped barely connected harness. Brake & Battery light flickers on & off when i hit a bump, draining brand new agm battery, alternator whines, no power to alt, trans, or fuel pump😥 BUT 3 mechanics say its electrical. Thinking ecm, since the whole dash is on & off. This seems worth a try.
it's humid as heck here in Texas, that's plenty enough to corrode stuff, heck my guns are in an air conditioned house and they rust like made even then.
Usually it doesn't matter. However if you remove the positive first, be really careful while you're doing it not to accidentally touch the wrench to any adjacent metal. Good practice says to take the neg off first, for the following reason. If you remove the neg first, it won't matter if you accidentally touch metal, since the frame is also neg. Once the neg is off, accidentally touching pos to the frame is unlikely cause sparks.
Well their are times when it works just fine no jerks or long time engaging. Some times it work great and others it wont which makes me think it more of an electrical problem. Sometimes the truck smokes and the radio flickers on and off its just weird. But thanks for your help scotty and awesome helpful videos u make man.
Guardiantony31 check the ground black wire going from the negative battery terminal to the fender. Sometimes the bolt at the fender becomes loose and/or corroded. Clean and tighten.
Great will try this tomorrow
You are the man Scotty
they could be, realize a computer module ultimately runs em both. but have the battery load tested first, often a weak battery sets such stuff off
Simply the best mechanic ever🖒
yes, it ran like a clock when done. It did start up after all at the end of the video, and it was towed into me not running
98 Dodge Caravan pulled codes for the vapor canister purge solenoid and the BCM. Replaced the vapor canister purge solenoid and still doesn't crank. Please help me before I spend a lot of money.
This is a good one! I never new connection way inside all that plastic could get corroded like that!
many things, but that small, I'd put some bars alumiseal in it and see if it stops altogether.
I'm been waiting to see a video of you working on a Pathfinder, I had to learn to disconnect the negative battery cable the hard way before.
I sprayed starter fluid in my mustang and it went boom
Ha
Did you do step one😂
You make it look so easy Mr Kilmer!!
Always AWESOME Scotty! Thank you.
So, I thought I may have accidently disturbed the old factory electric connection. The EGR vacuum regulator solenoid was given pulse voltage, so a good connection is probably vital. Now I want to thoroughly improve the connection at solenoid harness before other action. Do you have any advice on how to make a tight connection, or other advice to the above diagnose. I bought a bottle of Deox D100. Should I apply generously to the connector and harness? Thanks again in advance.
I need your help Scotty my car is in this same stage I’ve done all you’ve said and my car still won’t start
My Computer is in the engine compartment, why is it placed in a spot where it can get so hot and bake? By the way, my PCM only cost me a little over $200 and installed myself in a few minutes. Dodge wanted $1,600 to do the same. I am sure they would maybe have used a little more expensive brand new PCM but the refurbished I got has worked great for a year so far.
yes, I often leave out the really boring obvious parts.
we've been using ecu-renew at our shop to clean flooded ecu's its badass. all those flood cars cause the hurricane should be somewhat salvageable
venturi carbs get better gas mileage but must be kept very clean. Piston carbs will run dirty on shitty gas but don't work as well and get worse gas mileage
Excellent Scotty- Got any good advice on electrical display issue with Dashboard of 2006 Chrysler 300c?! I checked Oil - Water. For over heating issues. I'll move onto dust on fuses next. I believe there maybe a "Touching" or no slack in wiring in the engine compartment. I'll wait for your review. - She's got a new Engine - different from the Factory one that DROWNED because of the Faulty Gas Sensor.
if you have the actual sending unit that runs the gauge and there is no wire on it, no, that's not normal. but realize they can put sending units on more than one place
I don't use dielectrical grease on computer connections, too many terminals and it can make connectors not tight as the connectors won't fit on right then
Dielectriccal grease
thank you, I will try it after I get off work tomorrow.
You can say that again. Thanks for responding quickly. Your videos have been invaluable as I've worked on all many systems recently. I sprayed out my PCM connectors today just as you demonstrate here. Hopefully it will finally solve my intermittent driveability issues. Fingers crossed as I'm out of ideas. My car does runs great 90% of the time now. How about a video on power windows problems for older 4th Gen (93-96) F-Bodys? Or one on how do you scan these 94s 12 pin flashable PCMs? Thanks!
Did it work? I’m having issues with my 2010 Mustang GT my scanner ain’t giving me a code for a bad PCM just a PO443 which I already replaced but the check engine light ain’t going away & scanner is till giving me the PO443. After seeing this video I’m hoping it just needs to be cleaned just like Scotty did 🤞
hey scotty i have a 00 mustang gt 4.6 and i catalyst where taken off and its currently running rich i have no check engine light what do you think that is?
oil in vacuum lines means that the engine is pretty darn worn, or you have bad gaskets, like intake manifold or head gasket leaks.
i very much appricate your help with all the videos i have a 2004 Toyota prius .I watched your video on how to change the Hybrid synergy mechanical pump and i did replace with a new one . now the car will not even go into the acc mode to be able to start .I am doing a system reboot atm i am hoping the ECM will reset .if not could you help me locate the Ecm computer ? i will check that next i am used to Amerian made cars . gas conbustion engines i can rebuild a 350 blind folded , these Hybrids are another beast .
After reading this video, feel it maybe the ECM connector need clean? Do you have any opinion? By the way, thinking about buy a cheap ECM from eBay. Do you think the used ECM may need dealer re-program, even with the same make/model/engine? Thanks a lot.
yes it work,i got this problem ,last year mechanic told me computer was deprogrammed and rip me off with 500 dollars,this year a can of 5 dollars
do you spray inside the thing that connect back onto the pins, or spray a cloth and wipe it down?
Appreciate 5$ dollar can fix my nightmare 🙏🏻🙏🏻👌🏻👌🏻👌🏻keep it up ur a lifesaver
no, carbs need to be rejetted to run faster, and that takes a pro to do correctly
Scotty, after you spray the cleaner on you scrub it a little bit with a brush or something? Or do you just spray it and reattach the harness?
many things can cause that, from clogged intake manifold passageways to computer circuit or wiring problems. Try cleaning the intake first.
