Got 4.55 volts is that to low or would it be ok I got a good ground what else could it be beside pcm how can I check other wire

wilson84

Any body got any inputs

twoskinsoneman

try giving more info. No one here has a working crystal ball that I am aware
of

Lol I' was hoping someone had a crystal ball this has been an on going problem I just put the motor in and used wiring harness from New motor the po113 code came up and come to find out the wiring harness plug where it goes to pcm was different so I put the wiring harness from old motor on it the code went a way for a lil while but now it's back it's marking t run extremely lean and it's not shifting right I check the ground wire it's good and then when I check the plug for volts it's only getting 4.55 volts is there away I can check the power wire with out a live scanner

Rossco

No familiar with this generation of truck.

Is this a stand alone sensor? Two wire?

wilson84

It's a 2 wire sensor

Rossco

Does it look like this?



If so it's an RTD (Resistance Temprature Device) check the resistance across the pins.

wilson84

No that's on top of intake the iat is n the corregated tub that leads to air filter

Rossco

Yeah that's a stand alone IAT for a supercharged application. Works the same as the plastic unit.

Here check this out.

CLICKY

Reason why I asked is the 04-08 IAT is integrated into the MAF.

According to the 'CLICKY' the sensor voltage should be 5v. IDE say the supply is fine.

As I stated above I already know that I'm not getting the required 5 volts. It was there a month ago but not now I'm thinking pcm will need reflashed thanx for the inf o
