I have a 2005 dodge grand caravan. 1 week ago I had a hard start error codes P0344,P0339 & egr code.took it to a mechanic replaced cam sensor and egr valve. After awhile developed P0305 code drove for two days now Starys and dies error codes P0339& p0344 came back. Is the engine bad or could it be the pcm Mechanic's Assistant: Which particular sensor are you asking about? And have any trouble codes been triggered? P0339 crankshaft sensor, yes codes P0339&P03444 Mechanic's Assistant: Are you fixing your Grand Caravan yourself? What have you tried so far? No fixing myself

Hello and welcome to just answer, my name is \*\*\*\*\* \*\*\*\*\* I will assist you today. I am sorry you are having this problem but hopefully I can help. I doubt this is a "bad" engine. Most likely a PCM or the wiring/circuit(s) between the sensor and PCM. Do you know if the mechanic replaced the sensor with OEM Mopar parts or after market parts? Chris

Do not know if they about sensor
Automotive Expert
Okay, I asked that because I have had some issues with some after market cam and crank sensors on Chrysler built vehicles. Let me look over the diagnostic procedures for those codes and get back to you asap. Chris

Which engine do you have? The 4 cylinder or the V6? Chris

Thanks. Be right back. Chris

So after looking over the diagnostic procedures I am thinking you may have a problem with the engine wiring harness. I think the 5 volt sensor reference voltage may be intermittently shorting out somewhere. Have your mechanic check the wiring next. I have the diagnostic procedures for you and your mechanic in the links below. Hopefully this will help. Chris

Is there a way to check the PCM?I am doing this myself
Automotive Expert
Basically if you follow the diag, you check everything else, then if all checks good, then the PCM is determined to be the problem and then it should be replaced. Let me send you the PCM and sensor connector pinout pictures. Chris
