PINPOINT TEST G258127p18 : DTC P0340, P0341; RIGHT-HAND CAMSHAFT POSITION (CMP) SENSOR CIRCUIT RANGE/PERFORMANCE, CIRCUIT MALFUNCTION

G258127t67 : CHECK THE CMP SENSOR FOR CORRECT INSTALLATION
1. Turn the ignition switch to the OFF position.
2. Check the CMP sensor for correct installation.

- Is the CMP sensor correctly installed?

->YES
GO to Pinpoint Test G258127t68.

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

G258127t68 : 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 G258127t69.

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

G258127t69 : CHECK THE CMP SENSOR SENSING CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.
2. Disconnect the CMP sensor electrical connector, PI23.
3. Disconnect the ECM electrical connector, PI01.
4. Measure the resistance between PI23, pin 02 (Y) and PI01, pin 94 (Y).

- 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 G258127t69.

G258127t70 : 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 PI23, pin 02 (Y) 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
GO to Pinpoint Test G258127t71.

G258127t71 : CHECK THE CMP SENSOR SENSING CIRCUIT FOR SHORT TO GROUND
1. Turn the ignition switch to the OFF position.
2. Measure the resistance between PI23, pin 02 (Y) 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
GO to Pinpoint Test G258127t72.

G258127t72 : CHECK THE CMP SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between PI23, pin 01 (R) and PI01, pin 95 (R).

- 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.
