I have a 2015 3.6 grand caravan with a few problems that just started happening. I plugged in my cheap reader and it says there are 8 codes. po740,po523,po305,po113,po108,po222,po123,po300. I have been wondering if it might be something came unplugged or something like that. I looked at all of the fuses , they looked good. It will start and run for a second. The tow truck guy loaded it by driving it up on the flatbed, but it was hard to keep running. Any advise on where to start much appreciated

 

The P740 code maybe the problem keeping the engine running, That is a torque converter code. Does the engine stall when you put it in gear? If it does the torque converter is in lockup. That would be a starting point.

 

Hello, thanks for the reply. It won’t run when in park. I bought the van site unseen. I went and it was in nice shape and ran for a few seconds when I first looked at it. No sounds when it ran.

 

Will it stay running in neutral?

 

I will try that tonight. Thanks I’ll let you know

 

It will run/start for a couple seconds in neutral. then stall the same as when in park.

 

So the P108 code map sensor voltage is high, P113 intake sensor is high, P123 Throttle sensor is low and P222 Throttle sensor is low. You should have 5.0volts at the sensors. You need to have the wires check for either shorts to voltage. I would recommend to test the wires before replacing any parts.
