My Daughter bought a 2004 Dodge stratus It has a P0344 code but runs fine at 2000 rpm or lower above 2000rpm it bucks. Replaced cam Sensor with no success. can not get MIL light to go out. reset codes

Camshaft sensor,could be bad and check crankshaft sensor too.

you have to clear the codes after repair

First check the easy thing. Have your battery tested. Sensors very sensitive to failing battery. If the battery tests fine then you will need to change the Cam sensor probably a $30 part. On your truck remove the air filter housing & the cam sensor should be easily accessible at the front of the cyl head. Hope this works for you. Based on your P codes it should.

in my code book gave me intermittent loss of cmp or cpk
for 2.0 L are you having any back firing problems ?? iif so timing belt may have jumped one tooth . just trying to help hope this gives you some other things to look at ,good luck
oh look up code p1390 just found it . explains more what i was saying.

Did you check your camshaft position sensor circuits to see if they were working correctly or test the sensor itself before going out and replacing the sensor?....Didn't think so....

Lesson learned here? Diagnostic Test Codes (DTCs) DO NOT tell you what parts to replace. They only tell you which systems or circuits in your vehicle are not working as they should be. Then it is up to the person diagnosing the car to determine what is actually CAUSING the system or circuit to malfunction......Of coarse, this requires that you must first understand how the system is supposed to work...

Anyway, with some proper diagnosis, I think you will probably find that your cam sensor code (P0344) is being caused by a timing belt that has skipped a tooth (most likely).

Bad wires or connectors in the wiring harness that is losing contact at times can also cause that code. This can be verified by watching the cam sensor signal to the PCM with a lab scope and wiggle-testing the wiring harness to see if the signal drops out.

The cam/crank sync needs to be checked with a scan tool. If the sync PID is switching back and forth between YES and NO, then it is most likely a skipped timing belt. This is usually CAUSED by a bad timing belt tentioner pulley assembly.

Yup! they DO tend to buck a little when the valve timing is not correct!

P0344 OBD II Trouble Code Camshaft Position Sensor Circuit Intermittent...

code p 16 refers to crankshaft position/cam shaft position bank 1 sensor A--correlation====causes ---wiring---CKP sensor ( crankshaft position sensor )---mechanical fault

code p 0340 refers to -camshaft (CMP) sensor A bank 1 circuit malfunction ===causes wiring--CMP sensor--ECM
cosrs nothing to check the timing belt , just remove the oil filler cap and see if the rockers are moving when turning it over
the clue here may be bewteen the 2 codes , the word correlation and circuit malfunction so check the wiring, harness connections for pin corrosion and then substitute the ECM with a know good unit as the correlarion and circuit malfunction could be in the ECM
if the ECM program is not getting good reports for both sensors then it reasons that the piston and cam shaft are not timed properly and so will not allow it to start

it went from a hard cam sensor failure to an intermittent theres no magnet just a raised portion on cam.i think you got a loose terminal in the connector or a wire shorting or partly open from the sensor to the pcm

Have the exact problem. Replaced cam sensor and timing belt. Still happens intermittently. code is p0344.

you bypassed the wires that connect to the sensors? that would have been my first guess the harness that plugs into the sensor. after that i would check the ground connection from the ecm. wouldn't hurt to check the battery posts too. if the battery posts are oxidized you can have all kinds of goofy electrical problems. hope that helps.
