P0340 - CAMSHAFT POSITION SENSOR A CIRCUIT INTERMITTENT (BANK 1 OR SINGLE SENSOR)
| Description: | An inactive camshaft position (CMP) signal during cranking is detectable by the powertrain control module (PCM). During engine cranking the PCM monitors the crankshaft position (CKP) signal and injection control pressure (ICP) to verify the engine is rotating. If the CMP signal is inactive during this time a DTC is set. Electrical noise may also be detected by the PCM. When the noise level is sufficient to affect engine operation, a corresponding DTC is set. | |||
| Possible Causes: |

| Diagnostic Aids: | An inactive CMP signal causes a no start condition. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
