2000 Toyota Avalon 3.0 V6 has a misfire no codes on scan tool. No misfire showing on scan tool. How to locate manually. Also addressing Mechanic In A Box code scanners.
Thank you for being the honest guy that you appear to be ! I've been an honest Diesel Mechanic for 40 years and it amazes me how many greedy low life Mechanics are out there :(
After getting soaked so many times I decided I prefer self-soak; so I started to learn.
Thank you I wondered why I could only see 3 coils ,this is 1 of the best videos I have ever watched great information. I have been getting 3 codes p0 171 bank 1 fuel mixture to lean, p01133 now p0300, I have replaced all spark plugs, coils 2,4,6 found vacuum leaks, was going to order plug wires I guess that I need to pull intake and check the other 3 coils thank you so much. I cleared code and drove 100 miles and passed emissions and it did not code after 3 driving cycles then I got p0300 I have watched a lot of videos and you helped me more than all of the others I wish you a blessed Day!
Great video 👍 I have an 03 Avalon as my daily driver. In saying that I am watching videos to educate myself should a problem arise. I give you props for the rant . I believe people need to know so they don’t get ripped off from dishonest mechanics. Thank you. Keep the videos coming!! I am a new subscriber and will continue to watch!!!
I respect your character and care about maintaining your integrity in doing professional,honest work. Keep up the good work.
Very good presentation, not everyone is mechanically inclined and he is very clear and vivid in his explanation. A+
TY
Hi Ron, great presentations: videos, sound, and explanations. thank you sir. I subscribed and rang the bell.
Ron, very nice presentation and thanks for taking the time to share your experience.
Your comment on Denso really got my attention. I have has different Toyota models since a 1971 Corolla and have found that their engines really run BEST with Denso spark plugs. A dealer once told me it's because they are engineered for a wider heat range. Tried AC, Motorcraft, Bosch, NGK, etc. Nothing performs from idle to high RPM's like Nippon-Denso.
You are right, i have an old Toyota Sienna and at one time i put Bosch spark plugs on it and ran like crap. After that, only Denso spark plugs.
@@josephwood499 OMG, Bosch is the one company that I never ever will buy another product from. I had a Fiat that I put a Bosch replacement voltage regulator on. It failed within 2 weeks. Distributor cap and rotor on another Toyota. They also failed soon after purchase. An oxygen sensor on a Solara also was NO GOOD with the same code right out of the box. After that I never bought another Bosch and always tell the parts house NO BOSCH products. So much for German engineering, they are the worst. Use reliable Toyota parts or quality replacements. I never like having to replace something twice.
My purchased new 2000 V6 Camry came with stock double ground NGK iridium plugs, over 130K miles now and still going.
I've replaced coils on that engine on a Lexus RX and I found that the original could starts to get micro cracks around the 150k mark. Best to replace all 6 once one then two go also replacing all 6 plugs with Iridium long life plugs. What I also found was the oxygen sensors go around the 125 to 150k mark. A great engine but a lot needs to be replaced if you plan on keeping these ageing Toyota's going longer.
That's a lot of good Avalon info! Thanks!
Thanks for all that great info . My daughter just gave me a 1999 Toyota Avalon XLS.
Thanks Ron,
Really appreciate your teaching. Just wanted to know, have a 1997 1mz-fe and it misfires at around 45-60mph, intermittently.
I can't use my snap on scanner mode 6 as it doesn't allow me to but the OEM mode works fine.
How would you find a failing coil pack or HT lead? As mine has the waste spark system. No codes and only at high speeds like a shudder bit you let off the gas pedal it stops...
Thanks for your help
Great video, same motor, same issue, no codes. Going to follow your ideas.
Great Video, Highly informative, and up my alley since its only been this year I've started buying and fixing cars with electronics... Btw, thanx for the compliment (9:49). You obviously have quite a bit of experience, but I've never considered myself a contortionist, so here's an easy toyota spark plug hack I put together working on my '99 Sienna. An extended 17mm(11/16ths?) socket, 3 inch extention, and a 3/8ths knuckle attachment (in that order, add another 6 inch extension afterward if your using power tools instead of rachet) made it quite easy to avoid the air intake and take the back 3 spark plugs out in 15 minutes flat.
very helpful video, thank you Ron.
Good video. I agree you get what you pay for, always have. I don't see how the "circuit" was bad if it was coil pack, unless you consider the circuit in the pack to be problematic. I always use Toyota parts on my highlander. I have a fairly good Bosch scanner, but nothing like snap on. REALLY liked coil pack tool. Makes it way easy.
I agree with your rant at the beginning of this video
Thanks man saved me alot of time and frustration
Thx Ron; your detailed and honest presentation is refreshing to see. Great job
Thank you for this excellent video.
First off. Great video. Felt every word. Thanks for sharing. I have a question for ya? I'm not tech trained but 30 plus yrs also of back yarding. I have a friend that has a 2000 sienna 3.0 l similar to this motor different looking coil packs but anyways. This van runs great its intermitton at 55 to 75 ish. It will chugging like a misfire. Or bad plug. Kinda thing feels more electric than fuel to me. New plugs about 2 yrs ago. No real issues at other speeds and not every time. Toyota ran a check said possibly one of the cats. Replaced the middle. Still there. Mt question and opinion is a coil pack starting to get bad. It seems more often after it's warmed up than cold up hills at higher speeds intermiten. So my question was what is your opinion just shooting from the hip with a guess.
Great job. Shout out from San Diego Ca! I see youre in Cali as well.
Just over the hill in riverside county
yes, btw, Denso is the OEM supplier to Toyota.
on the 97 the coils are dual, so if 1 3 or 5 are bad, you change out the dual coil at front matching.
so if one is bad you replace the coil pack that is in 2. that doesn't fix it and one is still misfiring it's probably either the spark plug or the injector if you assuming the injectors are good is probably the spark plug or the connection to the spark plug and other words that contacts spring is broken and not contacting spark plug.
yes?
thank you . basic and simple to follow up.
Replacing the rear bank spark plugs is not that bad. Especially reaching around and unplugging them. Sometimes it’s easier to get at them from around the throttle body
My 2000 3.0 engine in my Sienna has 3 coil packs with lead and boot only on the 1,3,5 cylinders and the coil is $61 at Autozone. I'm glad I don't have this engine in my van, but this has helped me figure out why every two or three weeks I keep getting an ECL reading P1050 or misfire on #5. I drive it everyday so this misfire seems to happen when I've let it sit a few days in cold weather. Have even had the check light flashing but all cleared up and now I get this sporatic code popping up and it is keeps killing me from getting the moniters to reset so I can smog it😣
Good video bud👍🏽
Will a cheap (about $30) OBD scanner show misfires and cylinder after the fact? They do on my 2000 Corolla 4-cylinder 1.8L engine.
Thank you Sir
My experience on this engine was not bad changing all six coils. Did not remove the intake just used 1/4 inch tools, a skinny 10mm wrench. Cylinder 3 takes small hands or tool in from left and hand in from right. Removing the coils from the holes takes patients.
Thats exactly what my motor was doing,i pulled vvti controlers and screens but they were perfect.
Denso is it. 673-1301. I just put 2 in a 2002 Sienna. $57 each on Amazon. Denso is the best. 17 years on originals
Good advise..thanks
Thank you!
Thank you for great video. I am dealing with P0330 error on same car. Some how, it was temperature-dependable at beginning. At warm weather, it would give fuel tank evaporation error, at temperature bellow 32 F it was giving P0330 error. And it is appearing after some driving, not right away. Replacement of front spark plags and electric coils doesn't change anything - still the same problem. From temperature-dependable, over time it became temperature-independent. However, the tank evaporation error still persists at warm temperature. Any suggestion? Thank you.
A p0330 code means there is a problem in the knock senor on bank 2. As for the evap leak I recommend having a qualified mechanic that has a smoke machine check it. Evap leaks can be as easy as a loose gas cap to the most common problem of bad charcoal canister that houses the vent/purge solenoids.
Thank you for your common sense! BTW, any update on the knock sensor advice? You mentioned you were going to address it @ 14.23.
4 knock sensor code it probably set with the misfire they are very touchy go ahead and find your other problems correct the problems and clear the codes, then drive it to see if knock sensor code comes back. Sometimes we'll save you a lot of aggravation find to find something that is really not a problem. Always stay to the basics when you diagnose engine codes and a little research will always put you to the right path.
But ron i bought 4 break rotors and pads kit for my Avalon the were cross drilled and ceramic pads for 120 shipped they were great even after 60k miles not everything is junk
I concur Ron ;)
I disconnected all three front spark plugs and it did not change the engine idle. also touched it with some metal and no electrical current what so ever. How is this possible? would the car not die with three disconnected and taken out spark plugs? scanner is showing p0302 and p0304 codes
If a guy has to replace the 3 coils which brand do you use? Rockauto has too many to list and all could be worse than stock factory. I have thought about getting one out of a junk yard and keeping it in the glove box with a nut driver.
Denso
Hello, please if you can solve the problem I have on my Auris Toyota year 2014, after repairing my CVT box, 3 weeks later, I have the Engine check with the ESP on, after scanning i got 2 error codes, P1047 and p264, please tell me the exact fault, please give me a reply, thanks again
Where can someone purchase that ignition coil reader?
Good to know there are still some honest mechanics out there . I have the same car 2000 XLS Toyota Avalon. Recently check engine light and abs I think that's it light comes on started rough idling and RPMs on idle go up to about 2 RPMs higher than normal car will run rough and then magically all of a sudden all lights will go off pluss check engine light and run absolutely perfect has me baffled I'm not sure what's up.oh when check engine light and ABS light comes on. When I come to a stop setting there car seems to want to go because of higher idle and check engine light starts blinking but when everything goes off it's like the car never had a problem and runs perfect help please
I have the same problem, can’t figure it out?
@@jesusvazquez8373did y'all figure this out? I have same issue in 2000 Avalon. It will suddenly bog if I stomp gas pedal...intermittently. Slight rough idle sometimes....
I have a whole bank that isn't firing 1,3,5 and I'm lost on what it could be. Any help would be appreciated.
Is it safe to use full synthetic motor oil 98 Avalon engine when it’s over 300,000 miles?
Great video by the way!
It wont hurt it. But you may start experiencing small oil leaks because the molecules in synthetic oil are smaller than conventional oil.
@@SandCarServices Thank you very much!
On mine 2000 V6 Camry, only 3 coil packs not 6.
I had to replace my knock sensor harness also because of heat. I replaced the knock sensors also because of work to get to them. Denso only of course
Having a problem with over heating
CHECK ENGINE is a serious problem because DMV suspend your driving PRIVILEGE for it. First code said 02 downstream. So I changed that WITH DENSO and got a code for temperature to low. A dealer mechanic said THERMOSTAT (to dat); so I change dat; and temp. sensor. Next, codes are more stuff. I kept lookin' and found a YT vid that got me to the "overflow" hose under the intake. It was shot, all the coolant leaked once it reached operating temp's. I changed that with a new Toyota part, and as long I was there I changed the KNOCK SENSORS with TOYOTA's stuff PLUS NGK WIRES and expensive PLUGS and put it back with new gaskets. Then it gives me codes for INSUFFICIENT TEMP. AND KNOCK SENSORS AND AIR FUEL SENSOR, B-1&B-2, THROTTLE/PEDAL, it, intermittently dies/craps out once it reaches op.temp. and I am at my wits' end. It runs fine when I start it, accelerates strong, but sometimes slugs out. Still have that light on my dash. COMPUTER?? (I didn't change the oil cause WHY SHOULD I)
Any update with your issue?
I'm about to replace the knock sensor on my '00 Toyota Avalon. Shows 3 misfire codes and 2 knock sensor codes. Will a bad knock sensor cause the engine to suck through fuel like it's nothing?
The function of a knock sensor is the retard or advanced timing when detonation or (pinging) occurs. The misfire most likely are the cause for the bad fuel mileage. You said you have 3 misfire codes. If they are all on same side of engine cam timing might be a tooth off.
@@SandCarServices Thanks Ron, I too have the same problem as April Hass, Great advice. I'm starting there...
👍👍
OH my hell, just stick to ONE topic.
Nope! Never.
Well Said ... i seen this ad a the guy is a joke only a fool would buy it
Ok found out my timing chain is bad so it’s a rap I guess it’s stretched out. So junking my vehicle 🤦🏽♂️
just change it and change the water pump too?
did you know that you can buy six coil packs on ebay for $90.00 all six
Get what you pay for!
It's on a 00 avalon xl 3.0
This video could have been broken down into 10 different videos. All addressing a separate issue.
the Toyota is a really good about helping the engine not fail too bad when there's small problems like that and the RPMs will the whole Toyota fingers weird when they start a cold and when you running at high RPMs for a while idle sensor in a lot about 1100 give me a thousand and then after 2 minutes of idle it drops back down to seven hundred or so Toyotas are weird like that
I can 100% guarantee but there's no Avalon that has variable valve timing until 2005 so what the hell is VVT doing in the title for a 2000?
I got a 2000 Lexus Es300 and that has variable timing. It's basically the same engine in the 2000 Avalon. Lots of matching parts numbers between the two.
2002 Avalon with VVT.
Have a 1998 Avalon and replaced wires and plugs and coil pack #6 and still same problem then mechanic said it’s oxygen sensor and same problem, then same mechanic said one of my converters are bad due to smelling like eggs and burning fuel. So I take it to a muffler shop and tested out converters and all 3 were good. Now it’s at another shop and waiting to see what wrong with it I’ll keep you guys posted on what it exactly is. 🤦🏽♂️
I see you said it was timing chain, but, that engine had a belt and if broken, the engine has low chance of interference.
I would like 2 talk 2 u bout my car I got a 2001 Avalon and I did some things, and I still got the same problems, and i feel it like a misfire, but I would like 2 talk 2 u bout my car ! Will send u my # , or e-mail with my # , because real talk I feel u know wha u are doing and talking bout , thank u and please get with me
00
You talk too much. Just get down to the video description
I know, its how God made me.
Corono virus 19
there are only 3 coils on this motor.....the coil and the spark plug leads can be checked by testing with a known good component just as you did.
Peace+Opportunity
There are 6 coils on this engine. The other 3 are under intake on rear head.
A Toyota with 3 coils😂😂😂😂😂😂😂
@@jesusvazquez8373 Motprcycle? hahaha
The pre VVT 1MZ-FE engines have 3 coil over packs on the front with 3 wires the daisy chain to the back 3 spark plug boots. I have a 97 Camry with that 1MZ-FE engine.
@@jesusvazquez8373 I believe they did make a 3 cylinder engine ( Japan Only) back in the 60's but it didn't have coil packs
wasted 22 minutes on a 5 minute job?
