NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Check for Temporary DTCs or DTCs with the HDS.
Go to step 4.
Intermittent failure, the system is OK at this
time.
4. Update the ECM/PCM if it does not have the latest software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
5. Check for Temporary DTCs or DTCs with the HDS.
If the ECM/PCM was updated, substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the ECM/PCM was substituted, go to
step 1.
If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting. NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, then let it
idle.
4. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1)above70°C(158°F)
A/TinD,M/Tin3rd
Vehicle speed between 44 88 km/h (22 55 mph) for 5 minutes
Drive at a steady speed between 88 120 km/h (55 75 mph) for 10 seconds, then decelerate
(with the throttle fully closed) for 5 seconds
5. Monitor the OBD STATUS for DTC P2A00 in the DTCs MENU with the HDS.
Go to step 6.
If the screen indicates PASSED, intermittent
failure, the system is OK at this time. Check for
poor connections or loose terminals at the A/F
sensor (Sensor 1) and the ECM/PCM. If the screen
indicates EXECUTING, keep driving until a result
comes on. If the screen indicates OUT OF
CONDITION, go to step 3 and recheck.
6. Turn the ignition switch to LOCK (0).
7. Replace the A/F sensor (Sensor 1) (see page 11-221).
8. Turn the ignition switch to ON (II).
9. Reset the ECM/PCM with the HDS.
