Malfunction
1. Reset the PCM (see page 11-4).
2. Start the engine. Hold the engine at 3,000 rpm with
no load (in Park or neutral) until the radiator fan
comes on, then let it idle.
3. Hold the engine at 3,000
4,000 rpm for at least 60
seconds.
Go to step 4.
Intermittent failure, system is OK at this time.
Check for poor connections or loose terminals at
the knock sensor and the PCM.
4. Turn the ignition switch OFF.
5. Disconnect the C103 knock sensor connector.
6. Check for continuity between PCM connector
terminal A9 and body ground.
Repair short in the wire between the PCM
(A9) and the C103 knock sensor connector.
Go to step 7.
7. Connect C103 knock sensor connector terminal
No. 1 to body ground with a jumper wire.
8. Check for continuity between PCM connector
terminal A9 and body ground.
Go to step 9.
Repair open in the wire between the PCM (A9)
and the C103 knock sensor connector.
9. Check the knock sensor subharness between C103
and the knock sensor for an open or short. If it’s OK,
substitute a known-good knock sensor and recheck.
Substitute a known-good PCM and recheck
(see page 11-5). If the symptom/indication goes
away, replace the original PCM.
Replace the original knock sensor and/or
knock sensor subharness.

Intermittent failure, system is OK at this time.
Check for poor connections or loose terminals at
the CKP sensor and the PCM.
3. Turn the ignition switch OFF.
4. Disconnect the CKP sensor 2P connector.
5. Measure resistance between CKP sensor 2P
connector terminals No. 1 and No. 2.
Go to step 6.
Replace the CKP sensor (see page 6-61).
6. Check for continuity between body ground and CKP
sensor 2P connector terminals No. 1 and No. 2
individually.
Replace the CKP sensor (see page 6-61).
Go to step 7.
7. Reconnect the CKP sensor 2P connector.
8. Disconnect PCM connector C (31P).
9. Measure resistance between PCM connector
terminals C8 and C9.
Go to step 10.
Repair open in the wire between the PCM
(C8, C9) and the CKP sensor.
