DTC P1172:
11-15911-159
20. Monitor the OBD STATUS for DTC P1157 in the
DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 19,
go to the indicated DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the A/F sensor
(Sensor1)andtheECM/PCM,thengotostep1.If
the screen indicates NOT COMPLETED, keep idling
until a result comes on.
21. 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).
22. Start the engine, and let it idle.
23. 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 go to
step 22. If the ECM/PCM was substituted, go to step
1.
Go to step 24.
24. Monitor the OBD STATUS for DTC P1157 in the DTCs MENU with the HDS.
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 were indicated in step 23, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, go to step 1. If
the ECM/PCM was updated, substitute a known-
good ECM/PCM (see page 11-7), then go to step 22.
If the ECM/PCM was substituted, go to step 1. If the
screen indicates NOT COMPLETED, keep idling
until a result comes on. 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. Monitor the OBD STATUS for DTC P1172 in the DTCs MENU with the HDS.
Go to step 5.
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 idling until a result
comes on. If the screen indicates OUT OF
CONDITION, go to step 3 and recheck.
5. Turn the ignition switch to LOCK (0).
6. Replace the A/F sensor (Sensor 1) (see page 11-221).
7. Turn the ignition switch to ON (II).
8. Reset the ECM/PCM with the HDS.
9. Do the ECM/PCM idle learn procedure (see page 11-310).
10. 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.
