Codes

Hi guys I have a paccar mx and I have a code P1652. Anybody can help me with that code

 

Hello everyone. I need help. I have a paccar mx13, and I also have a code p1652. Somone can help me to understand this code. Thanks

 

According to Google it's high voltage to the ECM

 

Google can be your friend. I found that code. But can’t download it.

 

It says it’s either over charging and or a short circuit and it can Fry your ECM. It could be a faulty harness etc. It warns not to drive it until it’s checked out.

 

I'm working on it, when I put the ignition on the ECM sey the voltage is 12.7 but when started it going low 2.5 and don't accelerated more than 13 rpm I don't know what's the problem

 

Did you check the battery connectors ?

 

Yes and check the batterys too

 

Also sey the voltage control sensor is bad but I don't know where is located in my truck
