I have a 1997 dodge neon that quits unpredictably, can anyone help?

Question

I have a 97 dodge neon that will just die out. We have check the cam sensor, and the crank sensor but both seem to be good and working using a voltage check. The code that came up is loss of cam sensor but it still runs a little rought but it runs. The last bit of info i have is that it is was bought back by the manufacturer due to warrenty. So in other words the dealer couldnt figure it out so the had to by it back, thus leading me to beleive that maybe the PCM is bad thus causing a faulty reading. does Anybody have any info that might be helpful.

I have a 97 dodge neon. Its spits and spuders and then will just die out. Sometimes it starts right back up and will be fine and other times it takes awhile to start up and once started it runs really rough. We have had a code 54 come up all of the time, and code 11 come up sometimes. We have check the cam sensor, and the crank sensor but both seem to have the correct voltage. Leading me to beleive that the PCM is bad thus causing a faulty reading. Does Anybody have any info that might be helpful.

Answer 1

I have a Neon and have had numberous problems with electrics causing engine codes and the car to stop working.

Most of my issues actually went away with a new battery as weird as it sounds! Have you checked the wires for the sensor all the way to the other end to find where it might be shorting out?

Neons like it when you replace the spark plugs, wires and coil pack. But only use the cheap spark plugs.

Your issue most likely is NOT the PCM. They RARELY fail.
There is a TSB concerning intermittent stalls. The Cam and Crank sensors are listed, as are several other possibilities.
Chrysler uses an odd strategy with their cam/crank sensor signals.
There is a condition called "Sync", and if the compute loses "sync" it will die. There are several things that can cause it to lose sync, including the sensors themselves, a cracked or flexing flex-plate and damaged connections or wiring harnesses.
Without getting too "techy", the best thing you can do at this time is to take the car to a reputable repair shop who employs ASE certified techs. Ask that they read the Diagnostic Trouble Codes stored in the PCM. ans also that they read and interpret thee "freeze frame" that is stored with the code(s).
NOTE-->The freeze frame will only apply to the last code set. It may take a couple of attempts to dial into the cause of failure.

Good Luck and Merry Christmas

HERE IS A REPORT ON THOSE
Periodic problems on this vehicle are failures of the Engine Head Gasket, the Oxygen Sensors, the Vehicle Speed Sensor, and the Spark Plug Wires. Failure of the Vehicle Speed Sensor may prevent the vehicle from starting.
