―  CKP sensor terminal A
―  CKP sensor terminal C
•  Is there continuity?
Yes
If the short to ground circuit could be detected in the wiring harness:
•  Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
―  CKP sensor terminal A—PCM terminal 1J
―  CKP sensor terminal C—PCM terminal 1E
If there is a common connector:
―  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
―  Repair or replace the malfunctioning part.
If there is no common connector:
―  Repair or replace the wiring harness which has a short to ground.
If the short to ground circuit could not be detected in the wiring harness:
•  Replace the PCM (short to ground in the PCM internal circuit).
Go to Step 11.
No
Go to the next step.
6
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 11.
No
Go to the next step.
7
INSPECT CKP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Verify that the CKP sensor and PCM connectors are disconnected.
•  Switch the ignition ON (engine off).
•  Measure the voltage at the CKP sensor terminal C (wiring harness-side).
•  Is the voltage 0 V?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between CKP sensor terminal C and PCM terminal 1E.
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.

If there is no common connector:
•  Repair or replace the wiring harness which has a short to power supply.
Go to Step 11.
8
INSPECT CKP SENSOR CIRCUITS FOR SHORT TO EACH OTHER
