Anybody know what this code is for on a 2001 three quarter ton?

 

Battery temp sensor performance. There is a flash for it, TSB# 18-011-01.

 

Whats a flash? Could it be the code for Ambient Air Intake Temperature Sensor?

 

It's a software update for the ECM. The codes is listed as Ambient/battery temp sensor performance under service info but when you read the TSB it specifically says the code is for battery temp sensor.

 

I looked up the flash on Dodge.com, it says that the code is for gas engines, this p/u is a deisel. Does it still apply?

 

OOps, you are correct. I must have selected the 5.9 gas when checking. In that case, you are looking for a bad battery temp sensor or wiring. It is located under the battery in driver side battery tray.

 

Thanks Warlock, in the future how do I know about the codes without havin ta come here?

Is there a chance the code could be for Ambiant Intake Air Temp? I had some other guys tell me thats what it was.

 

I am a DC tech so I get my info directly from printed or online service manual. I believe the intake temp codes are P0112 and P0113. If you have an ambient temp sensor, it would only be an input to overhead consol, not ECM.

 

Thankyou Warlock, you have helped tremendously!
