P0301 - CYLINDER 1 MISFIRE DETECTED
| Description: The powertrain control module (PCM) continuously monitors the crankshaft speed and acceleration for each cylinder event. When the deceleration is detected the PCM uses the crankshaft position (CKP) and the camshaft position (CMP) signal information to determine which cylinder misfired. The DTC is set when the misfire event occurred in the cylinder due to a poor cylinder compression, fuel delivery concern or mechanical engine concern. | |||
