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.
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
condition)

Crankshaft Position Sensor Output
Wave Inspection
1. Measure the output wave between the ECM terminals
No. 99 and No. 100 using the scan tool or the oscilloscope
while engine cranking (start motor activated).
Notice
Check the segment or crankshaft position sensor and
air gap if cannot get the output wave as shown in the
figure.
Crankshaft Position Sensor
Insulator Resistance Inspection
1. Disconnect the coupling from ECM while the ignition
switch is in “OFF” position.
2. Measure the resistance between the coupling terminal
pin No. 100 and No. 69 using a multimeter.
Notice
Measure the check and ground terminal of the CKP
sensor if out of the specified value.

CAMSHAFT POSITION (CMP) SENSOR
The Camshaft Position (CMP) sensor sends a CMP signal to the Engine Control Module (ECM). The ECM uses this
signal as a “synchronized pulse” to trigger the injectors in the proper sequence. The ECM uses the CMP signal to
indicate the position of the #1 piston during its power stroke. This allows the ECM to calculate true sequential fuel
injection mode of operation.

Circuit Description
The CMP sensor sends a cam position signal to the ECM. If the cam position signal is lost while the engine is running,
the fuel injection system shifts to a calculated sequential fuel injection mode based on the last fuel injection pulse, and
the engine continuous to run.
Camshaft Position Sensor Signal Voltage Inspection
1. Measure the voltage between the ECM terminal No. 11 and No. 106 while the engine speed is at idle.
Notice
The signal voltage will be changed in the range of 1.2 ~ 1.7V.
Specified value
1.2 ~ 1.7V
