I took my car to a mechanic who wanted to charge 1,200 for replacing a head gasket, water pump, radiator, radiator motor. I decided to fix it all myself which I did. It starts but now after awhile it dies or it sounds like its flooded. I have the car manual and did the repairs correctly.

DTC P0336: CRANKSHAFT POSITION (CKP) SENSOR PERFORMANCE (2.2L - GASOLINE)

Description
Crankshaft Position (CKP) sensor signal indicates crankshaft speed and position. CKP sensor is connected directly to PCM.

"� An intermittent can also be the result of a defective reluctor wheel. Remove crankshaft sensor and inspect reluctor wheel through hole.

DTC P0341: CAMSHAFT POSITION SENSOR CIRCUIT PERFORMANCE

Description
Camshaft Position (CMP) sensor indicates camshaft position so PCM can determine which cylinder is misfiring when a misfire is present. Whenever PCM receives an intermittent signal from CMP, CMP resync counter will increment.

Code Enable Criteria

"� Engine is running.

DTC sets when PCM sees more than 15 CMP sensor re-syncs in 256 seconds (4 minutes 16 seconds).

Diagnostic Procedures

1. Perform powertrain diagnostic system check. After performing powertrain diagnostic system check, go to next step.

2. Turn ignition on, engine off. Connect scan tool. If no other DTCs are set, go to next step.

3. Start engine. Allow engine to idle. Observe CMP RESYNC COUNTER with scan tool. If CMP RESYNC COUNTER is incrementing, go to next step. If CMP RESYNC COUNTER is not incrementing, see DIAGNOSTIC AIDS .

4. Turn ignition off. Disconnect CMP sensor connector. See Fig. 6. Start engine. Observe CMP Resync on scan tool. If CMP resync counter stopped incrementing, go to next step. If CMP resync counter did not stop incrementing, go to step 7 .

5. Turn ignition off. Check CMP connector for poor connections. If problem was found, repair as necessary. After repair, go to step 9 . If problem was not found, go to next step.

6. Replace CMP sensor. After repairs, go to step 9 .

7. Disconnect PCM connectors. Check PCM connectors for poor connections. If problem was found, repair as necessary. After repairs, go to step 9 . If problem was not found, go to next step.

8. Replace PCM. After repairs, go to next step.

9. Using scan tool, clear DTCs. Turn ignition off for 30 seconds. Start engine. Operate vehicle within code enable criteria. If scan tool indicates diagnostic ran and passed, go to next step.

10. Using scan tool, observe stored information.

Diagnostic Aids

If PCM sees less than 15 re-syncs in 256 seconds, the counter is reset to zero. When a faulty
electrical connection is present, CMP reference activity counter will stop incrementing and CMP
Resync Counter will increment.
