Yes
Goto D4

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

D4 : CHECK THE LEFT-HAND BANK CMP GROUND WIRE FOR OPEN CIRCUIT

1. Measure the resistance between the CMP sensor electrical connector EN33, pin 2 (N) and the PCM electrical connector EN16, pin 69 (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 LEFT-HAND BANK CMP SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between the CMP sensor electrical connector EN33, pin 1 (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
