Hello, my name is***** the check engine light on? Is vehicle overheating? Thanks.

Customer: replied 5 months ago.
Check engine light is on because of gas cap. No it is not over heating. The temp gadgets isn't working since it started running rough and cooling fans are running constantly
Customer: replied 5 months ago.
Battery light comes on
Customer: replied 5 months ago.
Starts right up tho.
Expert:  Dan replied 5 months ago.

Ok, this would most likely mean the engine coolant temp sensor has failed. When sensor fails it causes vehicle to run rich "too much fuel" which is why you are seeing smoke. What engine do you have? I can give you replacement instructions. Thanks.

2003 Chrysler Town and Country

Ok, I need to be last to reply in meantime too. Thanks.

Ok I checked the diagnostic codes.
P 1684, P 0122, P 0118, P 0108, P 0204, P 1478 and P 1496
Expert:  Dan replied 5 months ago.

P1644 means battery has been disconnected, P0122 is related to throttle position sensor, P0108 is for map sensor, P0118 is for coolant temp sensor, P0204 is for cylinder 4 injector, P1478 is for battery temp sensor, and P1495 means 5v reference is too low. It sounds like a wiring issue, check the wiring harness from the injectors to the Powertrain Control Module (PCM). The insulation melts off the wires on the wires in the harness near the exhaust crossover. The wires need to be removed from the harness to check every injector control circuit. Also check the sub-injector wiring harness under the intake plenum for damage. Also make sure to check wiring going to map sensor. Let me know if you have questions, thanks.
