what is the rigth way to do this, so i can check codes.
mine is a 2001 ram 1500 QC has the digital odometer.

 

turn the key from the off position to the on position (but not start) a few times.

on - off - on - off - on


there is another test for the gauge cluster.
depress and hold the odometer reset and turn the key to on. continue to hold the odometer for a few moments until it starts the test.

 

why would it show P Done on the little odometer screen and what does it mean ?
ok i got it to do the CHEC thing but i didn't get a code it just had a little line flip across the screen
then all guages moved 1/4 , then 1/2 the all the way up on tach, speedometer, fuel, temp, volt,and oil pressure
so what does this mean ?
i took pics of the P Done thing and the Chec if you need to see them

 

just tried mine - also got P Done.
i think it means that the display is complete, and there are no trouble codes.
is your check engine light on ?

 

well i went and tried it again and got code P0113.[align=left]P0113 (M) Intake Air Temp Sensor Voltage High Intake air (charge) temperature sensor input above the[/align][align=left]maximum acceptable voltage.[/align]
i have no idea what that is and where i can find it i will look in the book
and see if i can find it.
ifanyone knows where it is please give me a shout.

thanksfor the helpdhvaughan
when i have it idling it shows no check engine light

 

intake air temperature (IAT) sensor is on the intake manifold, passenger side, up near the front, just off the end of the fuel rail, and behind the alternator. since its actually easy to get to, it must have been a dodge engineering mistake.

 

thanks man i found it.
yeah a part that you can get too easily.
i can get it at an autoparts store for like 14.00












BORG-WARNER - Ambient Temperature Sensor
does that look like the correct name for it ?

 

no, that doesn't look like it.
i'm not able to get a picture on o'reileys, but here is the same description on rockauto w/pic, and that't not it. thats a heat/air sensor.

ouch !! $25-40. damn, must be gold plated.

 

should i change both of them ?

oh yeah and where is the other one located
