Camshaft position sensor

Engine is 2.4L 16 valve DOHC. Had mechanic replace timing belt due to failure. Went to pick up car and check engine light on. Had mechanic use code reader to find the problem. Code states camshaft position sensor failure. Replaced sensor and car will not start, however if I disconnect the sensor the car will start. Any suggestions?

Had similar problems occur on various Chrysler products manufactured since 1986. What I did was remove the computer from the car and then take a Dremel tool with wire brush attachment and lightly buff all the pins of the computer--tops, sides and backs. After this I then take a jewelers round file and insert the tip into each connector pin hole and very lightly file it to remove any corrision. When I reassembling the connector plug to the computer I placed a good size dab of silicon grease on the plug in the center (acts as a seal when seated). This has eliminated the problem on four different vehicles.

the computer may need to be reflashed. if it is running then it is not a bad sensor. either of those being bad would cause it not to run.

actually there is a magnet. Its right behind the cam sensor. Had to replace it myself. just make sure you get the sensor from the dealer as well. You wont find the magnet anywhere but the dealer so you mine as well buy both at once.

2006 Dodge Caravan 2.4, V4. It has code P0340.

The P0340 code indicates a problem with the camshaft position sensor circuit. However, given the additional symptoms you've described, it's possible that there may be multiple issues contributing to the no-start condition. Here are a few things you may want to check:

Check the wiring and connector for the camshaft position sensor. Make sure the wiring is not damaged and the connector is securely attached.
Check the timing belt or chain. A broken or worn timing belt or chain can cause the camshaft position sensor to fail and can also result in a no-start condition.
Check the crankshaft position sensor. A failed crankshaft position sensor can also cause a no-start condition.
Check the fuel pressure. While you can hear the fuel pump activate, it's possible that it's not delivering the proper pressure to the fuel injectors.
Check the ignition system. Check for spark at the spark plugs and make sure the ignition system is functioning properly.
Check for vacuum leaks. A vacuum leak can cause a rough idle or a no-start condition.

It's also possible that the excessive oil on the spark plugs may be related to a separate issue such as a failed piston ring or valve seal.
If you've checked all of these components and are still unable to diagnose the issue, I would recommend taking your vehicle to a qualified mechanic who can perform additional diagnostics to pinpoint the cause of the no-start condition.

2001 dodge stratus will the coil pack spark if the vavles are bent

if your valves are bent ,then i take it your timing belt has snapped .which means your camshaft can not turn ., so you can not get a spark at the plugs.if it was the old distributor you would have been able to check the coil with a spark plug tester the trouble is with a coil pack it is controlled by both sensors and your ECU but due to the camshaft not turning so your camshaft position sensor can not tell the ECU to fire the coil pack.

- Faulty Intake Camshaft Position sensor
- Faulty Camshaft Position Solenoid Valve
- Engine mechanical condition - Valve timing off
- Intake Camshaft Position sensor harness is open or shorted
- Intake Camshaft Position sensor circuit poor electrical connection

05 Chevy Aveo Sedan sputters, jerks, check engine light goes off & on?

Depending on what engine you have, I know the 1.6 DOHC engine has the cam sensor right at the top front of the motor. You must make sure you have your timing belt serviced at the suggested intervals or you will have a large repair that you can't afford. The recommended service interval is 72,000 miles. If you do not have your belt changed at the service interval it will cost you upwards of 1,200 bucks to have it fixed after the valves are bent and need replacing.

Dohc focus overheating

You need to take off the timing belt (or chain) cover and see why the one camshaft is not turning. Maybe the belt for that cam broke or the cam has seized from a bad cam bearing. One camshaft should be for the intake valves, the other cam is for the exhaust valves.

2004 chrysler sebring 2.4l dohc.

Have you ever replaced the timing belt?? If not the problem is likely to be a loose worn out timing belt. A floppy belt will play havoc with the sensor signals and trigger a check engine light and a camshaft sensor code.

Removing Camshaft pulley on 2.5 Dohc forester motor

To replace the timing belt back guard you will have to remove both pulleys.There is a small bolt under each pulley holding the belt guard Use a large socket to hold the pulley while you break the bolt loose with a 17mm socket. I have just done this while replacing my head gaskets due to coolant boiling from the gasket leak.
