Circuit Description

58X reference signal is produced by Crankshaft Position (CKP) sensor. During one crankshaft revolution, 58 crankshaft reference pulses will be produced. PCM uses 58X reference signal to calculate engine RPM and crankshaft position. PCM constantly monitors number of pulses on 58X reference circuit and compares them to number of Camshaft Position (CMP) sensor signal pulses being received. If PCM receives an incorrect number of pulses on 58X reference circuit, DTC P0336 is set.
