Default P0340?

I replaced the cam sensor and still cant get the car to start. It will crank but will not start. Does anyone have any other suggestions?

Did you replace the sensor with a Chrysler part? Some aftermarket parts don't work well. Other than that, with a 2002, you could have a broken timing belt. That will bring you to a screeching halt and you can crank forever and not start.

When the timing belt breaks, most times, you'll either see a code between P0336-P0339 for the Crankshaft Sensor or between P0340-P0344 for the Camshaft sensor. Both sensors need to have input to the computer to run the engine and both stop sending those needed signal when the timing belt breaks.

Now, after saying all that, it could be a matter of either one of those sensors going bad, so if you check the timing belt and it's still good, the next step it just to replace the Camshaft sensor. Only use a Chrysler part if you do replace it.

Has the timing belt been changed? If not it has been on borrowed time.

Chances are it wasn't which was why the guy was selling it before he had to do it. It might not have went but I hate to say it, it sure as hell wouldn't be surprising if it did. It's a big job and if you do it you also should change the water pump, it may not be bad but it should be done. If you want more info do a search on timing belt and you will get a ton of information.

Thumbs up Re: P0340?

Thanks for all your help guys. The timing belt did slip. My uncle came by last night (25Yr. mechanic) and did all the diagnostics. You guys were absolutely correct on the fact that the 0340 code will show for cam, crank and the timing belt. My uncle has all the equipment to do the job so I got kinda lucky on this one. Thanks again for the help, It really came in handy.
