When is the P1346 BUICK code detected?The Powertrain Control Module (PCM) detected the actual cam timing and the target cam timing did not agree
P1346 BUICK Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine difficult to start
P1346 BUICK MeaningThe Camshaft Position (CMP) sensor input is used to detect an engine misfire. The Powertrain Control Module (PCM) also uses the CMP sensor signal as an input for modifying the fuel injection timing and for modifying the ignition timing.
The PCM receives information on the engine status from various engine sensors and then selects the most appropriate ignition timing settings from within the PCM's programming. The following are the most important inputs for determining ignition timing requirements:
- The engine speed
- The throttle position (TP)
- The intake air volume
- The engine coolant temperature (ECT)
- The knock sensor (KS) input
