30. Disconnect the jumper wire from the EGR valve 6P
connector.
31. Check for continuity between EGR valve 6P
connector terminal No. 6 and body ground.
Substitute a known-good PCM and recheck
(see page 11-5). If the symptom/indication goes
away, replace the original PCM.
Repair open in the wire between the EGR
valve and G101.

1. Reset the PCM (see page 11-4).
2. Start the engine.
Go to step 3.
Intermittent failure, system is OK at this time.
Check for poor connections or loose terminals at
the EGR valve and the PCM.
3. Turn the ignition switch OFF.
4. Disconnect the EGR valve 6P connector.
5. Turn the ignition switch ON (II).
6. Measure voltage between EGR valve 6P connector
terminals No. 2 and No. 3.
Replace the EGR valve.
Go to step 7.
7. Measure voltage between the PCM connector
terminals C18 and C28.
Repair open in the wire between the EGR
valve and the PCM (C18).
Substitute a known-good PCM and recheck
(see page 11-5). If the symptom/indication goes
away, replace the original PCM.

1. Remove the intake manifold cover and the rear
ignition coil cover (see page 9-4).
2. Check the PCV valve (A), hoses (B), and
connections for leaks or restrictions.
3. At idle, make sure there is a clicking sound from the
PCV valve when the hose between the PCV valve
and intake manifold is lightly pinched (A) with your
fingers or pliers.
If there is no clicking sound, check the PCV valve
grommet for cracks or damage. If the grommet is
OK, replace the PCV valve and recheck.
