Troubleshooting
Step
1 Was "Engine and Emission Control System Check"
performed?
2 Check CMP sensor and connector for proper installa-
tion.
Is CMP sensor installed properly and connector con-
nected securely?
3 Check Wire Harness and Connection.
1) Disconnect connector from CMP sensor.
2) Check for proper connection to CMP sensor at
"BLK/RED", "ORN" and "BLK" wire terminals.
3) If OK, turn ignition switch ON and check for volt-
age at "BLK/RED", "ORN" and "BLK" wire termi-
nals of disconnected CMP sensor connector. See
fig. 1.
Terminal "B+": 10 – 14 V
Terminal "Vout": 4 – 5 V
Terminal "GRD": 0 V
Is check result satisfactory?
