D : DTC P0345, P0346, P1340, P1341: LH Camshaft Position (CMP) Sensor

D1 : CHECK THE LH 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
Goto D2

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

D2 : CHECK THE LH CMP SENSOR FOR FOREIGN DEBRIS
1. Remove the CMP sensor and inspect for foreign debris.

Is the CMP sensor free of foreign debris?

Yes
Goto D3

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

D3 : CHECK THE LH CMP SENSOR RESISTANCE
1. Measure the resistance between pins 1 and 2 of the LH Camshaft position sensor.

Is the resistance 450 to 650 ohms?

Yes
Goto D4

No
INSTALL a new CMP sensor. CLEAR the DTCs. TEST the system for normal operation.

D4 : CHECK THE LH CMP SENSOR SIGNAL WIRE FOR OPEN CIRCUIT
1. Disconnect the PCM electrical connector PI01.
2. Disconnect the CMP sensor electrical connector PI22.
3. Measure the resistance between the CMP sensor electrical connector PI22, pin 1 (N) and the PCM electrical connector PI01, pin 68 (N).

Is the resistance less than 5 ohms?

Yes
Goto D5

No
REPAIR the circuit. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

D5 : CHECK THE LH CMP GROUND WIRE FOR OPEN CIRCUIT
1. Measure the resistance between the CMP sensor electrical connector PI22, pin 2 (G) and the PCM electrical connector PI01, pin 69 (G).

Is the resistance less than 5 ohms?

Yes
Goto D6

No
REPAIR the circuit. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

D6 : CHECK THE LH CMP SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND
1. Measure the resistance between the CMP sensor electrical connector PI22, pin 1 (N) and GROUND.

Is the resistance less than 10,000 ohms?

Yes
REPAIR the short to GROUND. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
Goto D7

D7 : CHECK THE LH CMP SENSOR GROUND CIRCUIT FOR A SHORT TO GROUND
1. Disconnect the PCM electrical connector, PI01.
2. Measure the resistance between the CMP sensor electrical connector PI22, pin 2 (G) and GROUND.

Is the resistance less than 10,000 ohms?

Yes
REPAIR the short to GROUND. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
Goto D8

D8 : CHECK THE LH CMP SENSOR SIGNAL CIRCUIT FOR A SHORT TO BATTERY POSITIVE
1. Turn the ignition switch to the ON position.
2. Measure the voltage between the CMP sensor electrical connector PI22, pin 1 (N) and GROUND.

Is the voltage greater than 5 volts?

Yes
REPAIR the short to battery positive. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
Goto D9

D9 : CHECK THE LH CMP SENSOR GROUND CIRCUIT FOR A SHORT TO BATTERY POSITIVE
1. Turn the ignition switch to the ON position.
2. Measure the voltage between the CMP sensor electrical connector PI22, pin 2 (G) and GROUND.

Is the voltage greater than 5 volts?

Yes
REPAIR the short to battery positive. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
INSTALL a new CMP sensor. CLEAR the DTCs. TEST the system for normal operation. If the DTC is repeated, INSTALL a new PCM.
