Circuit Description
The 58X reference signal is produced by the CKP sensor. During one crankshaft revolution, 58 crankshaft pulses
will be produced. The ECM uses the 58X reference signal to calculate engine rpm and CKP. The ECM constantly
monitors the number of pulses on the 58X reference circuit and compares them to the number of Camshaft
Position (CMP) signal pulses being received. If the ECM receives and incorrect number of pulses on the 58X
reference circuit, this failure code will set.
Crankshaft Position Sensor Resistance Inspection
1. Disconnect the coupling "E" of ECM while the ignition switch is in "OFF" position.
2. Measure the resistance between the coupling terminal pin No. 99 and No. 100 using a multimeter.
Specified Value
Notice: Measure the insulator resistance of the CKP sensor if out of the specified value.

Maintenance Hint
•
Monitoring the actual rpm through or
scan tool
•
Inspection the ECM pin 100, 99 about
short circuit with bad contact
•
Inspection the CKP sensor
•
Inspection the air gap between sensor
and drive plate
•
Inspection the drive plate (teeth condi-
tion)
•
Inspection the ECM
