Detection Condition

DTC P0320 indicates 2 successive erratic Profile Ignition Pickup (PIP) pulses occurred resulting in possible engine miss or stall. Crankshaft Position (CKP) sensor is mounted on engine block adjacent to a pulse wheel located on crankshaft. CKP sensor monitors crankshaft mounted pulse wheel. Pulse wheel has 35 teeth spaced 10 degrees apart with one empty space. CKP sensor indicates crankshaft position and speed information to PCM by monitoring pulse wheel. CKP sensor identifies piston travel by monitoring the missing tooth in order to synchronize ignition system and provide a way of tracking angular position of crankshaft relative to a fixed reference for CKP sensor configuration. PCM also uses CKP sensor signal to determine if a misfire has occurred by measuring rapid deceleration between pulse wheel teeth.
