PINPOINT TEST G531332p18 : RIGHT-HAND CAMSHAFT POSITION (CMP) SENSOR CIRCUIT RANGE/PERFORMANCE, CIRCUIT MALFUNCTION

G531332t67 : CHECK THE CMP SENSOR FOR CORRECT INSTALLATION
1. Key off.
2. Check the CMP sensor for correct installation.

- Is the CMP sensor correctly installed?

-> YES
GO to Pinpoint Test G531332t68.

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

G531332t68 : CHECK THE CMP SENSOR FOR FOREIGN DEBRIS
1. Remove the CMP sensor and inspect for foreign debris.

- Is the CMP sensor free of foreign debris?

-> YES
GO to Pinpoint Test G531332t69.

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

G531332t69 : CHECK THE CMP SENSOR SENSING CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the CMP sensor electrical connector, PI23.
2. Disconnect the ECM electrical connector, PI300.
3. Measure the resistance between:

CMP sensor connector ECM connector PI300,
PI23, harness side harness side
Pin 02 Pin 34

- 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 G531332t69.

G531332t70 : CHECK THE CMP SENSOR SENSING CIRCUIT FOR SHORT CIRCUIT TO POWER
1. Key on, engine off.
2. Measure the voltage between:

CMP sensor connector Battery
PI23, 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 G531332t71.

G531332t71 : CHECK THE CMP SENSOR SENSING CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. Key off.
2. Measure the resistance between:

CMP sensor connector Battery
PI23, 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 G531332t72.

G531332t72 : CHECK THE CMP SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between:

CMP sensor connector ECM connector PI300,
PI23, harness side harness side
Pin 01 Pin 07

- 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 CMP sensor. CLEAR the DTC. TEST the system for normal operation.
