P1341

: DTC P1341; LEFT-HAND CAMSHAFT POSITION (CMP) SENSOR CIRCUIT MALFUNCTION RANGE/PERFORMANCE

G258127t135 : CHECK THE CMP SENSOR FOR CORRECT INSTALLATION
1. Check the CMP sensor for correct installation.

- Is the CMP sensor correctly installed?

-> Yes

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

G258127t136 : 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

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

G258127t137 : CHECK THE CMP SENSOR SENSING CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.
2. Disconnect the CMP sensor electrical connector, PI56.
3. Disconnect the ECM electrical connector, PI01.
4. Measure the resistance between PI01, pin 68 (N) and PI56, pin 01 (N).

- Is the resistance greater than 5 ohms?

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

-> No

G258127t138 : CHECK THE CMP SENSOR SENSING CIRCUIT FOR SHORT TO HIGH VOLTAGE
1. Reconnect the battery negative terminal.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between PI01, pin 68 (N) and GROUND.

- Is the voltage greater than 3 volts?

-> Yes
REPAIR the short circuit to high voltage. CLEAR the DTC. TEST the system for normal operation.

-> No

G258127t139 : CHECK THE CMP SENSOR SENSING CIRCUIT FOR SHORT TO GROUND
1. Turn the ignition switch to the OFF position.
2. Measure the resistance between PI56, pin 01 (N) and GROUND.

- Is the resistance less than 10,000 ohms?

-> Yes
REPAIR the short circuit to GROUND. CLEAR the DTC. TEST the system for normal operation.

-> No
INSTALL a new CMP sensor. CLEAR the DTC. TEST the system for normal operation.
