STEP
Is CMP sensor installed properly and coupler
1
connected securely?
1) Disconnect coupler from CMP sensor.
2) Check for proper connection to CMP sensor at
each terminal.
3) If OK, turn ignition switch ON and check for
voltage at each terminal of sensor coupler

disconnected.
Terminal "B)" : 10 – 14V
Terminal "Vout" : 4 – 5V
Terminal "GND" :
Is check result satisfactory?
Was terminal "Vout" voltage out of specification in
Step 2 check?

1) Turn ignition switch OFF.
2) Disconnect couplers from ECM (PCM).
4 3) Check for continuity between "Vout" terminal of
CMP sensor coupler and engine ground.
Is continuity indicated?
