Hello. I was driving home last night and the check engine light came on. It was still on this morning. I bought this truck a week ago. It has 139000 miles on it. No EGR delete. No DPF delete. Seems to all be stock except for the Mopar batteries and cold air intake and coolant cap.

I stopped at Oreillys and they plugged it in and gave me these codes:
P132C-Turbocharger/Supercharger boost control A Voltage.

U0155-Lost communication with instrument panel cluster control module.
(Possible causes)-communication error.
-faulty instrument panel cluster.
-instrument panel cluster harness is open or shorted.
-instrument panel cluster circuit poor electrical connection.

B1317-Battery Voltage High

U0151-Lost communication with restraints control module(RCM).

P242B-Exhaust Gas Temperature sensor circuit, Range/Performance Bank 1 sensor 3.
(Possible causes)-Faulty EGT.
-EGT harness is open or shorted.
-EGT circuit poor electrical connection.
-Extreme changes in ambient temp soon after key ON, engine running.

P0578-Cruise Control Multi-Function Input "A" Circuit Stuck.
(Possible causes)-Faulty cruise control function switch.
-cruise control function switch harness is open or shorted.
-cruise control function switch circuit poor electrical connection.

P00-Fuel Cooler Pump Circuit Low.

The possible causes is stuff I have found on the internet today not that they are accurate. I am far from a mechanic. I have basic tools. Yet I would like to fix this issue myself. Just from the codes and some possible causes I have looked up, it seems that possibly all these codes could be electrical.

Anyone ever have these codes and figure out what to do.
Thanks in advance!!!!

 

The last code is P00 8 D. It put a face somehow.

 

that #3 egt temp sensor will leave you stranded on the side of the road....engine wont start ...computer thinks its doing you a favor .

fix is to replace the #3 temp sensor.

08's have a bad temp sensor part and later years have a different temp sensor part that less #3 temp sensor failure

sorry to say this...dont shoot the messenger...but If I were you I would want to know....you have the most problematic year for the 6.4. there is a firm ware upgrade that will prevent the DPF from flame throwing and there is even a better firmware upgrade that will monitor for excessive fuel in oil....not sure how that works...but it does and will prevent you from running the engine if too much fuel accumalates in the oil as a result of the regen process.

rocker arm tips early wear are a problem as well as lifters grenading.

 

Thanks for the advice speakerfritz. Hate to hear that I bought a troublesome vehicle, hopefully I can maintain it enough to last me.

With your response I assume that is the most troublesome code that I recieved. Anyone know about the Fuel Cooler Pump code??

 

I need any and all information about the P008 D code. What causes it and how do I fix it??

 

Don't know how to help with your problems, but I have a factory (no deletes) '08 6.4L job 1 with none of the problems mentioned by other responder. I'm right at 130K miles and am the original owner. I do need to diagnose intermittent slow cranking though.

 

have you checked the coolant level in the fuel cooler? check it with engine off. it uses the same coolant mix thats in your coolant tank.

 

After i I bought it I noticed that the fuel cooler was basically empty. I stuck my finger in there and there was hardly any moisture. I filled it up and have kept an eye on it and it is holding coolant. But the code almost instantly comes back every time I clear the code. Would it be possible to have an air lock or is something bad since it was empty? I'm clueless and can't seem to find any info on this code. Thanks
