C : DTC P0340, P0341: RH Camshaft Position (CMP) Sensor

C1 : CHECK THE RH 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 C2

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

C2 : CHECK THE RH 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 C3

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

C3 : CHECK THE RH CMP SENSOR RESISTANCE
1. Measure the resistance between pins 1 and 2 of the RH Camshaft position sensor.

Is the resistance 450 to 650 ohms?

Yes
Goto C4

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

C4 : CHECK THE RH CMP SENSOR SIGNAL WIRE FOR OPEN CIRCUIT
1. Disconnect the PCM electrical connector PI01.
2. Disconnect the CMP sensor electrical connector PI23.
3. Measure the resistance between the CMP sensor electrical connector PI23, pin 1 (Y) and the PCM electrical connector PI01, pin 94 (Y).

Is the resistance less than 5 ohms?

Yes
Goto C5

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

C5 : CHECK THE RH CMP GROUND WIRE FOR OPEN CIRCUIT
1. Measure the resistance between the CMP sensor electrical connector PI23, pin 2 (R) and the PCM electrical connector PI01, pin 95 (R).

Is the resistance less than 5 ohms?

Yes
Goto C6

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

C6 : CHECK THE RH CMP SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND
1. Measure the resistance between the CMP sensor electrical connector PI23, pin 1 (Y) 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 C7

C7 : CHECK THE RH CMP SENSOR GROUND CIRCUIT FOR A SHORT TO GROUND
1. Measure the resistance between the CMP sensor electrical connector PI23, pin 2 (R) 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 C8

C8 : CHECK THE RH CMP SENSOR SIGNAL CIRCUIT FOR A SHORT TO BATTERY POSITIVE
1. Measure the voltage between the CMP sensor electrical connector PI23, pin 1 (Y) and GROUND.

Is the voltage greater than 5 volt?

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 C9

C9 : CHECK THE RH CMP SENSOR GROUND CIRCUIT FOR A SHORT TO BATTERY POSITIVE
1. Turn the ignition switch to the RUN position.
2. Measure the voltage between the CMP sensor electrical connector PI23, pin 2 (R) and GROUND.

Is the voltage greater than 5 volt?

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 DTCs. TEST the system for normal operation. If the DTC is repeated, INSTALL a new PCM.
