"Check Grounds" .. lol. It's been awhile since I heard you say that last ...
I was only thinking this the other day when Matt had his graduate working with him. Surprised he never mentioned checking GROUNDS when he had that car with a no start😂
Hello Matt,
This video reminds us of your old videos 😊
THE GROUNDS 😂 this joke never die 😂
Good job 👍
You make me more and more confident in dealing with modern engine problem diagnosis.
Once you get the foundation down you start to see that it’s essentially the same concepts across all systems. If it’s a potentiometer- it operates the same as all of them. If it’s a pulsewidth modulated solenoid, they all essentially operate the same way.
Near 40 years mechanic , and only worked with 3 " Tier 1 " guys like Matt . Old guys retire and FNG's blank about carbs . New Student .
Love the circuit codes over the performance codes. P0017's and 18's. Nice job.
True that! Usually the performance codes mean a more significant repair.
Ahhhh, everybody was missing the GROUNDS!!! You're great Matt!
Hey man, just wanted to thank you for all your effort of teaching. Your content is top tier
Thanks so much for taking time to let me know!!
I can’t help but notice that my last comment is THE ONLY one without a like! You trying to give me a complex, Matt? 😂
Hahaha there I gave you a nice big heart AND a like hahaha!!
@@SchrodingersBox That's more like it. 😊
Enjoy your weekend, Schrodingers Box
Can't wait for the next video

From Nick Ayivor from London England UK 🇬🇧 ⏰️ 22:29PM Good Evening
Thanks as always my friend!!
I have a fun one in playing with right now. Customer states they have a soft brake pedal. Attempted to bleed the brakes and could not bleed the front drivers caliper. Further diagnosis showed that fluid was not being sent out of the abs module to the hardline for that wheel. Fluid is coming in and out through the feed and return lines, and every other line to and from the abs module has flow. I'm working with no electrical diagram for the connector at moment.
As always, another great tutorial.
Thank you!! This was a really basic one. $80 in diagnostic equipment would diagnose it!

Good to see You. 🙂
Good to see you too bro!
Saw it from my lawn chair
Haha!!! Nice!
good job enjoyed the video simple and to the point thanks
Thanks as always!!!
Oh boy, GM keeps making those induction covers worse and worse. That one is pretty tame compared to what's on the newer V6 engines.
What no scope! Ha ha. Nice job love the approach. A simple resistance check for the win. Of course having that nice Topdon is a plus.
Thank you for another very informative video!
Yeah of course I wanted to go with the scope for sure just because it so cool but honestly it showed to be unnecessary and I do like showing that this can be 100% diagnosed using less than $80 in equipment.
Like what i see and add my skills
You may not be a mechanic in your day job but I consider you a mechanic and also a diagnostician. You could certainly go to work in a shop and be a lead tech.
Well thank you!
Hey thanks Loving it big guy really good videos brother
On your tombstone it will say buried in the GROUND!!!!😂😂 let it go man 😁
Hahahaha that’s what I want!!
Typical interchangeable solenoids are the same color, if the intake and exhaust are like black and silver or grey then probably not going to do SWAPTRONICS?? I appreciate checking the new part resistance for the viewers but if I go to the story to buy the part, I do the resistance test there, if the parts guy delivers the part, I order 2 and test it while he is waiting and take the other one back untouched. So this means I do not buy parts online as I also like to support my local parts guys.
It appears you did not take the bad part to the store since its still in the head and your new part is black connector, I would not expect that? With the original parts and color difference due to different part numbers, I would expect a resistance value to be different also, I guess the AM new part is black from that company? Thanks for the DIY level checks.
if you had an open in the sensor couldn't you have done a "continuity test " ? if there's an open there would be no continuity correct ? thanks great video
I did. That was the resistance test. It tests continuity too. In fact for a second it did show an open.
Hello. I'm a DIY mechanic. I'm about to buy a scanner. I was thinking buy a Xtool D7 but I want to ask you before. What do you recommend me buy the D7 or the Topdon?
Topdon. While the XTOOL is great, I have had a lot of users report issues with customer service if they have issues because the only contacts are in China
Topdon and Autel have US offices.
Here's a little trick when trying to measure the resistance of a solenoid. Try to avoid putting the probes in to make contact directly with the terminals. It's actually possible to have the wire that the terminal attaches to inside the solenoid to be broken, only to have it momentarily connect to the pin while we are trying to check it because we are pushing on the pin trying to make a connection. One of the best ways around that is to slide test leads onto the terminals and then connect the ohm meter to them. Another way is to use small alligator clips. But of course, not everyone has those. So, what they can do instead is take appropriately sized butt connectors and slide them onto the pins in the solenoid connector. Now use the butt connectors to connect the ohm meter leads to the terminals. That reduces the fumbling around trying to make and hold the connections.
BTW the solenoid open test and the solenoid shorted test in scan data actually mean the same thing. From the "computer's perspective" when the solenoid is turned off (and yes this is a pulse width modulated circuit) the voltage should be high because these are ground side switched. Of course, when the solenoid is turned on the voltage at the computer pin should be low. The computer compares the circuit command to the circuit state. If either the circuit is open OR the control side of the circuit is grounded, then the voltage at the computer's pin would be low when it should be high and that sets the fault. So those pids allow us to see what the computer thinks the circuit is doing while we work to confirm both the actual circuit condition as well as see if the computer can see it correctly. There are variations to these pids in other models and years that can take this to a more advanced level and separate those two test states. GM, Ford and some others do these fault test states for the majority of the circuits that connect to a module. They quite often save a few steps in the diagnostics.
Thanks very much. Always appreciate your in depth perspectives and advice!!
I did try to get something to fit over those tiny terminals to get a better ohm reading but they either kept falling off or touching each other. I am strongly considering getting a U-term kit!!
@@SchrodingersBox It's a great asset in the tool box. I take mine with me when presenting hands on classes. Fortunately leads that get damaged are easy to replace.
What about cleaning the exhaust solenoid?
That would have no effect. We can see that mechanically it has no obstructions at all because it was able to achieved the desired cam positions with no issue. It does however have high electrical resistance. Eventually it will fail electrically the same way the intake one did.
They get replaced in pairs, they have about a 50-60k life on them.
So just a heads up, maybe when you tested the exhaust your needles weren’t properly connecting at the sensor, or that sensor is going to set a code any day now. I’ve done loads of these GMs and both intake and exhaust read around 12-18 ohms
That may be but this check engine light has been on for months and no exhaust VVT codes were showing.
I totally agree the resistance seems high but given the nature of customer’s assets and the fact it’s functional and for all I know may remain functional for years, I decided the limited funds for fixing this car are best put to more serious known issues. Right now we are just trying to pass emissions and that’s all.
@@SchrodingersBox yeh no I totally get that, I’m not ridiculing you or anything for not selling him both solenoid. But you were questioning why the resistance was so high so just clarifying for you for future reference that both of those solenoids should in fact be the same
You are right i like better old school like the old days👍
I do too but at the same time we have to adapt. Had this been a mechanical fault we would have to either go higher tech with the diagnosis or start taking engine covers off.
@@SchrodingersBox well go the old way take the covers off good job boddy as all ways👍
Matt I'm pressure testing my injectors, 97 Dodge ram 360 original injectors. The pulse choice goes from 1 to 50, and then higher up to 200 I think . That seems like a big jump, I don't want to hydrolock my engine. I hate to ask but your thoughts? Are there steps I can take post testing to ensure I don't cause that condition. I just changed my tampon, please speak freely
Hi Joe. Rare that one can speak freely these days lol- at very least get cancelled!
Not sure I understand your question. Sounds like you are using a device to activate the fuel injectors by applying a pulsewidth- maybe 1ms up to 50ms and you check the drop in pressure using a gauge?
@@SchrodingersBox yes
Gotchya. Yeah I can tell you I have done up to 3 pulses without any hydro lock. If you are concerned then simply crank the engine maybe 2 or 3 seconds between tests and it will push the fuel right out the exhaust. But you would probably have to run like 10 pulses to hydro lock. It really only puts out less than a milliliter of fuel per test.
@@SchrodingersBox the cheap pulse tester I bought has 4 modes. Mode 1 is 1 pulse. Mode 2 is 50 pulses, then it goes over a 100 pulses on mode 3 and 4. I watched scanner Danner use one and was using 10 pulses I think. I'm sure the milliseconds which sure matter. I think I'll be okay with advice tho. I'm loving this subject and wish I had a nice scanner, love your work. If I can chase the rough idle down on my 97 without wasting money on parts the vehicle did not need, I may invest in something better than a hand held OBD2 scanner. Thank you so much
....edit) not sure what milliseconds Dan used
Those dorman solenoids are as good as autolite iradium xp spark plugs. Not worth the box they put them in. OEM ac Delco are the same price.
It’s all they had in stock at a price that customer could afford at the time
"Same price", depends on where you buy them from. Corporate chain parts store, yes they are ripping you off on price and charging the same price. That Dorman Solenoid runs anywhere from $20 all the way to $70, depending on where you buy it from. OEM $40-100.
I have been using more and more Dorman parts in the past 2 years. Mainly as a test to see "how bad they are". I have not had any bad parts in that time.
@@mph5896 Iv got 2 sets of these exact same solenoids that the customer bought and I replaced them with AC delco. Just because a part makes something "run" does not mean that it makes it "run correctly" New and good are 2 different words. Just the same that trouble codes and part numbers are 2 different things.
@@SchrodingersBox Current Advance auto price. 40.50 for Dorman. 51.21 AC Delco. Both in stock. I think they are 50 from the dealership. I get using cheap part if its 500 but 20 bucks? Seems silly to me.
@@SchrodingersBox Yeah I guess to me thats the issue. Either they can afford to fix their car right or they get it fixed somewhere else. Unlike yourself I have to make a living off of my reputation. You got a day job and make movies on weekend.
Parts lottery :D
This looks like the same as my sisters Terrain.. I put in an ultra cheap twelve dollen fI33bay solenoid (fr33SHIP) and it worked great for at least a year.. and then she sold it. I believe it was the exhaust side, but I don't recall now
I'm a DYI'er. I recognise my limitations. I'm told by a mechanic my Body Control Module was "unfixable". I wouldn't know where to start and if my mechanic tells me he can't fix it im certainly f×××××!!!
Well I can say 100% that’s not true because I am not a mechanic and I have videos where I fix BCM’s. I mean at very minimum you replace it and program a new one. It’s always fixable one way or the other.
What’s the year make and model? What’s the symptoms and whys he saying it’s unfixable?
nobody pronounces the K in Knipex
I went to school with a girl that had a last name of Knipple. She pronounced the K. 😄
Hahahahaha!! I would have also claimed the N is silent too lol
Since when do German engineers do anything that's sensible, even with the pronunciation of their tool names.
