PINPOINT TEST G531332p17 : CRANKSHAFT POSITION (CKP) SENSOR CIRCUIT RANGE/PERFORMANCE, CIRCUIT MALFUNCTION

G531332t61 : CHECK THE CKP SENSOR FOR CORRECT INSTALLATION
1. Key off.
2. Check the CKP sensor for correct installation.

- Is the CKP sensor correctly installed?

-> YES
GO to Pinpoint Test G531332t62.

-> NO
INSTALL the CKP sensor correctly. Reconnect the sensor. CLEAR the DTCs. TEST the system for normal operation.

G531332t62 : CHECK THE CKP SENSOR FOR DEBRIS
1. Remove the CKP sensor and inspect for debris.

- Is the CKP sensor free of debris?

-> YES
GO to Pinpoint Test G531332t63.

-> NO
CLEAN the sensor and wheel. INSTALL the sensor. Reconnect the sensor. CLEAR the DTCs. TEST the system for normal operation.

G531332t63 : CHECK THE CKP SENSOR SENSING CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the ECM electrical connector, PI300.
2. Disconnect the CKP sensor electrical connector, PI21.
3. Measure the resistance between:

CKP sensor connector ECM connector PI300,
PI21, harness side harness side
Pin 02 Pin 30

- Is the resistance greater than 5 ohms?

-> YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G531332t64.

G531332t64 : CHECK THE CKP SENSOR SENSING CIRCUIT FOR SHORT CIRCUIT TO POWER
1. Key on, engine off.
2. Measure the voltage between:

CKP sensor connector Battery
PI21, harness side
Pin 02 Negative terminal

- Is the voltage greater than 3 volts?

-> YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G531332t65.

G531332t65 : CHECK THE CKP SENSOR SENSING CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. Key off.
2. Measure the resistance between:

CKP sensor connector Battery
PI21, harness side
Pin 02 Negative terminal

- Is the resistance less than 10,000 ohms?

-> YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G531332t66.

G531332t66 : CHECK THE CKP SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between:

CKP sensor connector ECM connector PI300,
PI21, harness side harness side
Pin 01 Pin 06

- Is the resistance greater than 5 ohms?

-> YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
INSTALL a new CKP sensor. CLEAR the DTC. TEST the system for normal operation.
