CKP Sensor Status

The scan tool displays Angle, Time A, or Time B. This parameter indicates the engine position sensing mode. With both CKP sensors A and B working properly, this parameter should display Angle. If the PCM detects an incorrect condition with CKP sensor A, the PCM will command TIME B mode. If the PCM detects an incorrect condition with CKP sensor B, the PCM will command Time A mode.
