Watching this while I’m at vision training in Kansas City. Can’t get enough of automotive diagnostics. Yet again another excellent video by positive lead diagnostics.

Very concise and to the point training. Thanks for keeping everything simple and understandable. You're the only Teacher I've seen using the KISS system. KISS stands for: Keep it simple stupid.

im all my years of fixing vehicles i have never had rodent damage to the wiring here in the UK, i guess our mice dont like wires, it never ceases to amaze me the stupid places where they run the wiring on these cars, it makes it so hard to do checks and repairs, great vid by the way.

Wow it's a great job of you to discover this difficult holidays. You are so wonderful. I loved this video. You are really excellent. Keep up your wonderful work.

Thanks for the video, didn't resolve my issue but got my head straightened out and allowed me to eliminate a few things when I was overthinking. Also when you stated it was weird it would be low voltage I believe it is because it measures the difference between your 5v reference and your ground, so when you had 4v on your ground your difference would only be 1v instead of the 5v the computer was supposed to see.

Absolutely awesome video again from positive lead diagnostics

Well done! Nice fix! Thanks for the video!

Well done. Your vid,s are very educational. Keep it up 👍

Great narration and communication skills here..any concious tech or self repair individual can follow right along..

Me sirvió demasiado tu explicación, muchas gracias por compartir!!

Nice Diag Tom, well explaied, you made that look easy, good use of the pico, cheers mate thanks

nice one tom, love your electrical stuff

Nice work find abs great detective work , keep it up

Good work man! Great stuff!

Tom, good video as always. cheeers Amigo

perfect diag bro keep it up

Mouse in the house. Good work, really great content. Keep it up

Nice job Love the whisper effect

Learning all the time, nice one.

Thanks for this video. Hello from Russia.👍👍👍

Thank you Tommy. Good job.

Great diag! Love your vids

Who ever said mice were cute? Nice find and fix Tom!

Cool this video helped me to find my problem thanks

Good catch Tom

Well executed video.

Excellent troubleshooting Tom. My first impression was what could be possible wrong with 2017 model. Thank you for your hard work. Cheers.

Great work TOM people don’t know how hassle is to create video edit and then post

Excellent work.

Good work!

v.nice video & great channel.thax

Interesting video! I'm doing a similar check on my SLK350. Question, would it not have been much faster to just each of the lines for continuity between the ECU connector and the sensor connector?

great video man thank you, keep doing your thing buddy. Im not a mechanic by any means but ive always worked on my own vehicals. That being said, i ran into an issue with my vw jetta not accelerating and your video gave me some good insight.

great find

Very good ! Remember the basics testing circuits must be loaded to get a true result. Excellent job One more test that you could have done was to take your test light and use it to ping your pids. This will also give you a clue to the integrity of the wires going to the pcm . Keep up the good work... Docn2mx

excellent video friend tom

Great job Tom 😉🐭🐭🐭🐭

you need to use manual focus for odd shots like that, if the camera/device allows it. this once again shows and proves that all the electronic garbage needs to go away! it seems clear to me, that when a simple tiny rodent can disable any vehicle within a moments time, there's multiple major low level fundamental flaws involved....... towards the end of video you seemed kind of unsure about your diagnosis, but from what the camera showed, you are doing a great job and learning fast! never stop learning!!!!

Thanks for sharing.

Jerry at it again

Nice find and fix

How were you able to tell which wires were 5v ref, ground and signal by looking at that wiring diagram? New Volkswagen dealer tech trying to wrap my head around reading the wiring diagrams. Thanks!

Nice diagnostic Tom can you make a video on how to use odis

EXCELENTE AMIGO

thank you for sharing

Great video Tom. The last couple of years we have a real plague of weasels and martens here in Belgium. Those little buggers love to chew up your whole car 😁

Good job

exelente buen video

I have an issue that's not too different. My accelerator pedal doesn't give the full power when I press it all the way down. I can tell it's not full power cos I set cruise control to a much faster speed than my current speed and when I engage it, with the pedal all the way down, the power noticeably increases. So I have come to the conclusion it is likely an issue with the pedal due to the cruise control still being able to use full throttle. Bit of an odd one but I'm grateful for cruise to be able to test it and work around it

Hey, so I have a gti mk5 and it drives fine but when I try to push the gas pedal all the way down the car just revs and it doesn’t gain any power/mphs don’t go up. The car kinda just goes dead until you let off the gas and easy back into it then starts going again. I was wondering if ever came across this issue.

Very nice video, is the pinout the same on golf mk6?

Hi my app position D reads 40% at tickover 100% half depressed. Any thoughts?

Would like to see and/or know how you managed the repair.....

Hi I got a new sensor the problem still there, do you think this can be a wire problem?

excellent.

Hi Tom great fix I was thinking of buying the VAG scan tool VAS 6154 because I’m beginning to see that the newer VW and Audi cars after you have retrieved the Fault code from a module there is not much information to actually fix or diagnose the issue I was wondering if you had followed the GFF from the VAS tool how you think they would’ve gone about fixing the issue? As an example there is a shop that called with fault codes on a 2013 Jetta hybrid pertaining to the DSG transmission I’m subscribed to VW Erwin repair information system but there is no information on transmission fault codes matter fact there is no information on air bag HVAC etc... the only thing I find is the engine fault codes I work primarily on VAG cars and what I want to know how good is the fault finding information on the factory tool including resistance test and scope wave form I think that there is a scope that you can attach to the VAS tool right ? I think the factory tool number is VAS 6356

My 08 Sienna,has the same symptoms. When trying to rev up, the RPM stays the same,does not budge. It’s the APP sensor,right ? And some other lights come on too, thanks

Good diag Tommy, a lot of folk would have fired parts at that fault. Not a nice place for a repair. Steve.

Hi bro 2013 Passat VW throttle valve position sensor low in put static fault.What will be problem?,

Good job! Why the sensor signal 2 is half of the other one ?

Awesome

Great video but i have a stupid question how did you know each pin function ?? Like when you said this is 5v and this Gnd ?? I am asking because most of the wiring diagram don't clarify that .. thanks once again keep it up

if lose ground, why signal wire didn't have 5v??

Good work man great can you use a snap on tool for next time

lo que pasa es que tengo mi vehículo, un Jetta A4 modelo 2004 STD., el detalle es que de no de acelerar, le cambiaron el cuerpo de aceleración electronico se programo y nada no jalo, mandaba que el voltaje era bajo en el escáner, se cambió el pedal electronico, y siguió igual no acelera, los voltajes ya son los correctos, pero nada, yo que soy el cliente opte por prenderlo pero con el sensor de posición de alrbom de levas desconectado y jalo, aceleró pero se siente un poco inestable una ves que aceleró y avanzó se le quita lo inestable pero se siente arranado, mi duda es si el sensor del árbol de levas influye en eso. porque sin el sensor del árbol acelera solo en las mañanas se batalla para encender y se siente faltó de potencial... ya no tengo tanta confianza en mí electrico ni en mi mecánico .

Hi Tom. A few months ago when i was driving on the road and the speed was about 100-120 km/h, I took a signal as "brake assist is defective". Do you have an idea what it would be ? Shall i replace something ?

Brother if get high voltage cricket what v can do? and make the video for high voltage cricket.

Any experiece where the cables are for AMG Mercedes. I have P2122 Circuit D Low voltage.

Buy the way could you do a full video of the factory scan tool on a car with a real fault I’m very curious how all the functions work like when you have a fault and the way the tool would help you start a diagnostic up to a pont where you find the problem including looking up the information like wireing diagram and connectors view and pin outs I look on U tube and there is no good video of someone using the factory tool that would be a very cool video to see what I use for diagnostic tool is a VCDS wireless interface and also a Autel they work great but there is no help after you have found the fault code especially on newer cars because it seems like the information is very much liked to the VAS tool

Hi there I have the same problem, can you help me please?

Hi Tom, where do you get the schematic of the sensor connection ?

Nice fix. I would be afraid an LED test light would give you a false reading though (although it didn't). A 300mv incandescent test light would still be safe to test that wouldn't it? Thanks for the videos!

Hi Tom where you getting from wiring diagrams for euro cars

So, you used the LED type test light because it is a 5V circuit..but, given that there is no switch transistor in the computer and the sensor ground simply continues to computer gnd..could you have used the regular incandescent test light?

is it safe to test ECM pins with test light. current could damage the computer

Hi Tom, Just wondering, if the apps is a potentiometer why was there no signal voltage at the connector despite having 5v ref at the connector?

2003 Toyota Tacoma I replaced my throttle position sensor and it fixed the issue for one day and then I received the code P2127 same problem with no acceleration

I'm not sure if I missed it, but why was the signal low with a missing ground at the sensor? I heard Tommy say it as well. I would expect signal high. Or am I missing something?

Excellent tutorial! Just curious what the cost to repair something like that would be? I’m guessing close to $1,000?

one smart mouse. i wonder where he got the wiring diagram to know which wires to chew?

So why it's reading 4.1 volt on ground and not 5 volt when with connector plugged?One more question , circuit low means the ground is open?

Signal wire must have been open, surely? Did you swap what you thought were ground and signal at the sensor?

When the whispering starts... I can tell you're getting close to finding something! =)

so what did you go with? butt connectors? solder? new harness?

How do we stop mice/rats doing this. It seems that’s what’s happened on my car too.

What brand is your testlight ?

Can the peddle cause a no crank/start? I replaced the throttle body and still no crank... I have the peddle to replace could changing it start my vehicle.... Code p2127

Good diagnostics, but hard to effect repairs and even harder for the owner to stop rodent encroachment.

awesome diag man, what back probe and leads are you using, is it a kit ?

Excellent diagnostics. Tom.. But i'm sure you wanted to smack Mickey for having you repair those wires in that spot..No fun

This is my exact problem :(

excellent video I want to buy testlite link me it

i change wire engine..same situation p2122 p2127 cannot repair must change the wire the cost 200dolar..huhuhu my fault use datatech managent join the standart ecu wire..

I know scanner dinner taught you , but you don't have to sound like him ! Relax be yourself .. thanks for the informative video. Lol.

Same problem with my car Fiat Patil diesel engine

Good job I keep a little tin cup under the hood for some rat poison and I know there are eating it

Basic? apart from the equipment and knowledge of circuit charts. I understood mouse ate it.

Why people leave thumbs down 👎 but not leave comment saying WHY?????

Bom

And the mystery is ... how did you know , witch wire is for what , from this wiring diagram ? :)
