•  Measure the voltage at CMP sensor terminal A (vehicle wiring harness side).
•  Is the voltage 0 V?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify if there is a common connector between CMP sensor terminal A and PCM terminal 1A.
If there is a common connector:
•  Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to power supply to determine the malfunctioning location.
•  Repair or replace the malfunctioning location.
