nector and ECM 33P connectors, then recheck
the DTC.
1. CMP Sensor Peak Voltage Inspection
Turn the ignition switch OFF.
Disconnect the CMP sensor 2P (Natural) connec-
tor.
Turn the ignition switch ON and engine stop
switch " ".

Connection: Gray (+) – Black (–)
TOOL:
Imrie diagnosis tester (model 625) or
Peak voltage adaptor
with commercially available digital multimeter
(impedance 10 MΩ/DCV minimum)
Is the voltage more than 0.7 V (20 ° C/68 ° F)?
YES
NO
2. CMP Sensor Circuit Inspection
Turn the ignition switch OFF.
Disconnect the ECM 33P connectors.
Check for continuity between the CMP sensor 2P
