42. Determine which cylinder had the misfire.

Replace the faulty injector.

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).

46. Measure voltage between injector 2P connector

ground.

Go to step 47.

Repair open in the wire between the injector

and the PGM-FI main relay.

47. Turn the ignition switch OFF.

48. Check for continuity between body ground and the

PCM connector terminal (see table).

Replace the injector, then recheck.

Repair open in the wire between the PCM and

the injector.

1. Remove the intake manifold cover and the ignition

2. After checking and recording the freeze data, reset

the PCM (see page 11-4). If there is no freeze data of
misfiring, just clear the DTC.

3. Start the engine, and listen for a clicking sound

from the injector in the problem cylinder.

Go to step 4.

Go to step 31.

4. Turn the ignition switch OFF.

5. Exchange the ignition coil from the problem

cylinder with one from another cylinder.

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

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

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

tool or the HDS.

Go to step 8.

Intermittent misfire due to ignition coil fouling,

etc. (no misfire at this time).

Go to step 9.

9. Turn the ignition switch OFF.

10. Exchange the spark plug from the problem cylinder

with one from another cylinder.

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

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

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

etc. (no misfire at this time).

13. Determine which cylinder had the misfire.

Replace the faulty spark plug.

Go to step 14.

14. Turn the ignition switch OFF.

15. Exchange the injector from the problem cylinder

16. Let the engine idle for 2 minutes.

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

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

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

tool or the HDS.

Go to step 19.

Intermittent misfire due to bad contact in the

injector connector (no misfire at this time). Check
for poor connections or loose terminals at the
injector.

19. Determine which cylinder had the misfire.
