Step
3 Wire harness and connection check
1) Disconnect connector from CMP sensor.
2) Check for proper connection to CMP sensor at "BLK/
RED", "RED/YEL" and "BLK/ORN" wire terminals.
3) If OK, turn ON ignition switch and check voltage at "BLK/
RED", "RED/YEL" and "BLK/ORN" wire terminals of
disconnected CMP sensor connector.
CMP sensor voltage
Terminal "B+": 10 – 14 V
Terminal "Vout": 4 – 5 V
Terminal "GND": 0 V
Is check result satisfactory?
4 Was terminal "Vout" voltage in Step 3 within specification?
5 Ground circuit check
1) Turn ignition switch to OFF position.
2) Measure resistance between "BLK/ORN" wire terminal
of CMP sensor connector and engine ground.
Is measured resistance value less than 3
6 Was terminal "B+" voltage in Step 3 within specification?
7 CMP sensor check
1) Check CMP sensor and signal rotor tooth referring to
"Camshaft Position (CMP) Sensor Inspection in Section
1C".

power supply circuit.
If wire and connection
are OK, substitute a
known-good ECM and
recheck.
"BLK/ORN" wire is open
or high resistance
