Go to step 30.

Repair open in the wire between the PCM and

the ignition coil.

30. Check the engine compression (see page 6-11).

Substitute a known-good PCM and recheck

(see page 11-5). If the symptom/indication goes
away, replace the original PCM.

Repair the engine.

31. Turn the ignition switch OFF.

32. Disconnect PCM connector B (24P).

37. Measure resistance between injector 2P connector

terminals No. 1 and No. 2.

Go to step 38.

Replace the injector (see page 11-177).

38. Exchange the injector from the problem cylinder

with one from another cylinder.

39. Let the engine idle for 2 minutes.

40. Test-drive the vehicle several times in the range of

the freeze data or under various conditions if there
was no freeze data.

41. Check for a DTC or a Temporary DTC with the scan

tool or the HDS.

Go to step 42.

Intermittent misfire due to injector fouling, etc.

Make sure the injector connections are secure.
Check for poor connections or loose terminals at
the injector connectors.

42. Determine which cylinder had the misfire.

Replace the faulty injector

(see page 11-177).

Substitute a known-good PCM and recheck

(see page 11-5). If the symptom/indication goes
away, replace the original PCM.

43. Turn the ignition switch OFF.

44. Disconnect the injector 2P connector from the

problem cylinder.

45. Turn the ignition switch ON (II).

Sensor Circuit 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 C22 and body ground.

Repair short in the wire between the PCM

(C22) 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 C22 and body ground.

Go to step 9.

Repair open in the wire between the PCM

(C22) 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.
