Famous p0172

So it seems the sensor is good, guess we need to go to the PCM.
The PCM is located behind the glovebox, if you can post a picture of your PCM connectors I can probably label the one you need to check.

 

Ok ill continue with that tomorrow. 11pm here and got work tomorrow. Ill check that in the morning thank you so much!.

 

Ok I probably won't be around much during the day, it's been crazy busy at the shop.

 

No worries i work from 7am to 6pm so should be posring around that time. After testing the cables ln the pcm what wpule be the next steps? Ir i do get reading and if i dont

 

Do note that the sensor needs to be plugged in during this test.
If we have battery voltage at the PCM I'm not exactly sure what to think, Toyota PCM's rarely fail. If we don't have power there then the wire is broken somewhere between the PCM and the sensor.

 

Okok thank you. If its not failing ill have to check all the wiring then. I do remenber this was a goverment vehicle and had cop lights and everything inside. Could it be possible that they cut one to connect something like radio signals or strobe lights. Hopefully thats the case.

 

Hello. Just got to work the tacoma. Any clue where is the pcm?

 

Behind the glovebox.

 

Ok i got it here. Where should i start testing

 

Ok so for what i read on the pic is this two. Green and black and blue right?

 

Should be the bottom connector, left column, 6th pin from the bottom, should be a Green wire.

 

So this two if im not mistaken.

 

Mine is different it has 6 connectors instead of 4

 

Something isn't right here, this is an 06 Tacoma 2.7L correct?

 

No. 2015.

 

I was going off your profile, it says 06

 

Oh shoot thats my old truck. I got this from a goverment auction and upgraded.

 

Ok so it's gona be the 2nd connector from the top, 2nd row of pins, 5th pin from the left, still a Green wire.

 

Dont see a green wire on the second row

 

Someone was here already i see a lot of wire tape and some labels. And one wire is completely covered in ductape. On the connector second row i see white blue, blue, red, brown and pink.
