TOYOTA NO START OR STALL WITH SHORTED COIL IGF CIRCUIT PULLING DOWN ALL COILS AND SETTING ALL COIL C

[@alinkkila]

Man you saved my van from the junkyard!!!! I love you!!!! long story short..........Toyota tech's $460 problem not fixed(TPS REPLACED AND MAF REPLACED) told me it would be 1100 more for a new throttle body that is was the IAC motor was bad(time to leave at that point).....my normal mech......was like "NO CLUE MAN" then said it was the ECM 4 days later. THIS VIDEO SAVED MY TOYOTA. 2004 Sienna XLE limited 292,693 miles Now running strong yet again. Had a bad coil pack up front. unplugged it she fired right up.

[@jamesdanner7850]

+Amber Linkkila sweet!!! Love those stories. Thanks

[@PineHollowAutoDiagnostics]

Fantastic diag, James! Very clear explanation of the signals and logic, thanks. Oh and don't give away the fix in the video title...the viewers want SUSPENSE lol

[@jamesdanner7850]

+motoYam82 hmmmm. Suspense. . I'll try not to ruin the next one. Ha.. thanks bro

[@emtscythe3782]

Excellent find. Knowledge of the circuits and research truly helps. Great video James.

[@jimisp]

Thank you, so much you are a saviour. My sienna had all 6 coils codes, after hours of searching, it turned out that all three rear coils 1, 3, 5 were bad. I almost gave up, so I swapped the front coils with rear ones and put the plenum back and started the car on three coils and that worked.

[@tamare2002]

James, I must say THANKS. I was facing the exact same problem/sympthom in my 2006 Toyota Matrix: The engine started, some time kept running for a few minutes then stalled. A general misfire appears with all 4 codes at the same time: P0351, P0352, P0353, P0354. I got my car into two different workshops and they couldn't replicate the failure. I decided to do something by myself and got the Electrical Schematics. My Why Tree analysis narrowed to the IGF or the Ground system so I also checked the circuit cables for shorts, but never tried the coils because in the two workshops, both of them "CONFIRMED" the ignition coils were good (BIG MISTAKE). So I was lucky (actually was my son's idea): I just unplugged the ignition coil #2 (and the Fuel Inyector #2 too) and Voila!, the car runs, NOT STALLED. We replaced the Ignition Coil #2 and done. Thanks again for your video. May I suggest to modify your video title? (It took me a lot of time to find it) something like this: TOYOTA NO START OR STALL, ALL ENGINE COIL CODES P0351, P0352, P0353, ... P0356.. AT THE SAME TIME. During my research I notice there is a lot of people with the same problem around.

[@jamesdanner7850]

+Jairo Contreras glad to be part of your success. Thank you

[@kyhomegarage3430]

Great diagnosis very informative and professional

[@rudymedina8659]

Good evening James, I have similar problem on 2013 toyota camry 2.5. In the 25 years of doing mechanic i never had one like this. 👍

[@baxrok2.]

Sweet fix James. Honestly, what a terrible design when one bad coil can disable the car entirely! Thanks for posting this.

[@jamesdanner7850]

+Baxrok2 first for me

[@flyman1340]

Been working on this a week! You just saved my butt!

[@chadboros5234]

Thank you sooooo much! I spent three days looking for my issues and you solved it in one video for me lol 😊

[@TheOfficialWickedOne]

Great find! I’ve been a tech for years and never seen this. Thank you!

[@billrimmer5596]

Thanks James!! Good to know that one coil can jack up the whole system. Seeing the 5 volt ref pulled down is what we will have to check for. Always love your videos!!!

[@Judo_Jones]

Awesome work man! A True Technician!

[@jamesdanner7850]

+Michael Jones thanks but don't forget Clark

[@freestyleskyline]

Dunno if gou read these, but this was extremely helpful and straightforward. It can be difficult to test ignitors on toyotas, but looking for the 5v with the key is a great test for the igf

[@Joseph-tf4hu]

Thank you for sharing this video. I have this same issue with my 2006 Highlander.

[@mikeeustice4452]

great video haven't seen that to much how I remember what the terminology is I go by IGT= I got trigger IGF=I got fire

[@jamesdanner7850]

+Mike Eustice that's a good one. Cause during editing, I realized I kept pausing or mixing the 2 up

[@02lowrider62]

Very informative video good job, GO CLARK your my HERO

[@J.T672]

HI james , I'm a toyota tech myself and to be fair you made it look easy , nice 1 great video

[@jamesdanner7850]

+James Twibey ahh. The perks of editing... ha... thank you

[@drbsr1948]

Nice job James and nice of you to thank clark even though he doesn't seem to want to be. 😁

[@jamesdanner7850]

+Danny Berry he tells me that the boss pays him to be nice to me

[@davesministry7789]

Excellent video. You stuck with your original testing direction to the very last circuit. It sure "felt" like a passcode or security device shut down, which would have led me in the wrong direction. Good work. Keep going. At the end of your video's you say believe. Believe what?

[@jamesdanner7850]

+daveS ministry simple answer.... Jesus. Not a preacher tho. Just acknowledging the gifts given to me. And stating the simplicity of accepting the gift of God's sons death to pay for our sins. The verse comes from after his resurrection when even the ones who knew him didn't believe at first.

[@davesministry7789]

Thank you. You are a preacher Jesus Christ. Nothing wrong there. Good job. .Jesus died for our sin's according to the scriptures, and rose from the dead according to my gospel. Believe= trust and rely upon. Believe he died for you're sin's paid for them with His shed blood, was buried, and rose from the dead. Proving He was able to justify us. This is the gospel. God bless you. Continue on.

[@leebarnes655]

Thanks Clark, another nice one James. Who's gonna pay for the wrong plug installation? Didn't notice the difference in spark plugs when doing that job - wow. Might have to set up water injection and hope for the best?

[@jamesdanner7850]

+Lee Barnes the customer said he did them. Easy to overlook if u don't do it by trade

[@leebarnes655]

Yep, the one and only person that gets a pass on that kind of mistake, just hope he learned to NOT allow it again.

[@benjaminrich9396]

great find. nicely done.

[@jimmyfavereau]

same exact symptom on my 2000 echo then turned into , no spark.. I been chasing the problem for a week , even tried a junk yard ecu, still no spark, cheap coils are less than a year old but Ill inspect in the am.. thanks !

[@chekelley6861]

Great diagnosis!!

[@robertmullen2480]

thanks James we have a lot of Toyotas with this ignition system in our family, good video

[@littlebeargaming8267]

Excellent video, James, but how does unplugging the coil allow the vehicle to start without finding the short and fixing i?

[@jamesdanner7850]

+littlebear gaming the short was internal to the one bad coil. And the igf circuit runs thru all 6 in parallel. a failure like that anywhere in that circuit shuts the whole thing down. Even tho it misfires with the one bad one unplugged, the coil fire confirmation signal from the other 5 can now make it back to the computer and it will continue to run

[@littlebeargaming8267]

Thank you, James for the explanation.

[@motorcyclesandridingfree2899]

Good find for sure on that as some would have chased the security code first. But typically security will shut down fuel and not spark so going after the coil codes was the right call.

[@jamesdanner7850]

+MJR Performance thank you. .. I was suspecting that and almost said it was a possibility in my written description, but didn't go that far on research after the repair . So I kept my mouth shut.

[@tamare2002]

I want to say, in the workshop they confirmed fuel was never shut down: they verified fuel pressure and fuel inyectors and no problems found every time the car stall.

[@erickvqz77]

Great video,keep the good job James danner

[@kostaskosta7617]

Thanks for that video You help me very Mach My car go to 3 engineer and and no one use the multimetet you save me a lot of money and time if I were to your country I would go to your garage Thank very mach

[@SteveRobReviews]

Thanks to Clark , what would you do without him . Interesting vid Danner lot of twists and turns . 👍👍

[@jamesdanner7850]

+STEVE ROB Clark is the glue that holds us together

[@uriahbleue1947]

Can you explain why a shorted coil would show .8 then jump to 5 volts? I can’t wrap my head around it.

[@Joseph-tf4hu]

Linking this video to the PO codes would help, I was fortunate to follow a wiring diagram to the IGF and IGT.

[@cardoc2477]

great job

[@rhkips]

Haha, rule #1 of automotive repair: Remember, the world hates you. If the part is inaccessible, start your diagnosis there. :D Another good find, too! Do all the weird problems come to you, or are there other diagnostics guys in the shop?

[@jamesdanner7850]

+rhkips just me

[@wysetech2000]

Well done, Jim.

[@jamesdanner7850]

+wysetech2000 .. thanks

[@mara93autoservice35]

Hello sir now Highlander limited the same problem with u now how to do !

[@diagnosedler8637]

I hade some case , Slo....with tighten loose engine ground

[@jamesdanner7850]

+Dler Abbas loose grounds can do many weird things

[@devinsnaples]

great fix keep'em coming those jobs always jam me up could call you scanner jammer just a thought

[@billrimmer5596]

Did Clark have to pull the manifold or was he able to change the plugs and coil by just removing throttle body? Thanks again!!

[@jamesdanner7850]

+Bill Rimmer he just removed the throttle body and got to that bad one pretty easily

[@haywardsautomotive6156]

Nice troubleshooting & diagnosis James. Whoever changes the plugs may have to break torque, fill up the wells with intake valve cleaner and let them soak...glad they didn't give him 3/4" reach plugs or it could have gotten real ugly!

[@jamesdanner7850]

+Hayward's Automotive we did wonder how close to the Pistons they were

[@haywardsautomotive6156]

I started thinking it should have 3/4" reach plugs & for a 2006 Toyota Sienna 3.3L it actually calls out for 3/4" reach plug NGK IFR6T11

[@paolosmith2323]

I managed to make it work without the computer analyzer. My 2006 Sienna was doing the same thing, it quit and I had to have it towed to my house. What I did was to unplug the coils one at the time, then clear the codes and try to start it. I got lucky, it it was the second one I tried, in the front, once I unplugged it and cleared the codes the engine started, it had a miss because of the missing spark. I replaced that coil and it's running fine.

[@rudymedina8659]

I have been trying to solve but no luck. I have probe the wires on coils, injectors pulse, crankshaft and cam sensors, also tested fuel pressure, key🔑 and coresponder. Everything seems to be working. I have even tried the disconnect on each coils, cleaned mass air sensors,. throttle body And the only code is p1604 and even cleared. But no luck. Any suggestions would be helpful. Thanks for your videos

[@salehhamid]

Neet job . Thanks for filming it

[@martinarrieta7779]

[@نورسلطانأبوسلطان]

Hi. I have a similar situation, the car starts and stalls and writes codes for all four ignition coils. But at the same time, I have 5 volts on the igf wire, and each coil pulls this voltage to ground. What can you advise? Thank you very much!

[@philh9238]

number 5 might of shorted because the coolant that goes to the throttle body was leaking on it??

[@jamesdanner7850]

+phil holbrook I wondered who the one would be that pouted that out first. Nice observation. And it was that way before Clark touched the throttle body.

[@jamesdanner7850]

+James Danner ....pointed. ....

[@Truthful7777-o9p]

Hello.. My car engine starts and dies after 2 seconds. The scanner says P1305 igniter circuit malfunction. I erased the code but still kept coming back once I start the engine again. Is ECM faulty? Thanks.

[@McAdamsMechanics]

What volt meter computer is this?

[@001thomas3]

To change coils without removing upper intake just remove throttle body swing out of way gives just enough to reach all

[@kc360awareness]

Great job “DannerDanner”

[@bilalpakstni9704]

Very useful for me

[@rrmech11]

It's about time. Lol James I enjoy your diags

[@thatmechanicguy8773]

Very typical for this era Sienna. The best way to attack this is to go after the coil that has freeze frame data stored first. Usually, that’s the faulty coil and fixes the issue. For some dumb reason Toyota’s set immobilizer codes all the time. They’re almost always false codes.

[@ajscars1081]

I have the exact same issue with the exact same codes I unplugged all the coils connectors and measured the voltage between IGF and GND while the key in the run position, it was 0V. I also measured the voltage across IGF and B+ and it was almost 7V. Is it possible to be a bad ECM?

[@ajscars1081]

Yup, it was indeed a bad ECM
