10. Turn the ignition switch OFF.
11. Disconnect the A/F sensor (Sensor 1) 4P connector
and ECM/PCM connector A (31P).
12. Check for continuity between body ground and A/F
sensor (Sensor 1) 4P connector terminals No. 2 and
No. 1.
Repair short in the wire between the A/F
sensor (Sensor 1) and the ECM/PCM (A6 or A16).

(2004 model)
NOTE:
• Information marked with an asterisk ( ) applies to
2002-2003 models.
• Information marked with double asterisk (
) applies
to 2004 model.
1. Reset the ECM/PCM (see page 11-4).
2. Start the engine. Hold the engine speed at
3,000 rpm without load (in Park or neutral) until the
radiator fan comes on.
3. Check for a Temporary DTC with a scan tool or the
HDS.
Replace the A/F sensor (Sensor 1) (see page
11-279).
Go to step 4.
4. Test-drive in D3 position (M/T in 3rd gear). Starting
at 1,600 rpm, accelerate using wide open throttle
for at least 5 seconds. Then decelerate for at least
5 seconds with the throttle completely closed until
the readiness code or Temporary DTC P1164
comes on.
Replace the A/F sensor (Sensor 1) (see page
11-279).
Intermittent failure, system is OK at this time.
Check for poor connections or loose terminals at
C101 (located under the right side of the dash),
C401 (located under the left side of the dash), the
A/F sensor relay, the A/F sensor (Sensor 1) and the
ECM/PCM.

NOTE: If DTC P1162 is stored the same time as
DTC P1167, troubleshoot DTC P1162 first, then
troubleshoot DTC P1167 (2002 model only).
1. Reset the ECM/PCM (see page 11-4).
2. Start the engine. Wait for at least 80 seconds.
Go to step 3.
Intermittent failure, system is OK at this time.
Check for poor connections or loose terminals at
C101 (located under the right side of the dash),
C401 (located under middle of the dash), C402
(located under middle of the dash) the A/F sensor
relay, the A/F sensor (Sensor 1), and the ECM/
PCM.
3. Disconnect the A/F sensor (Sensor 1) 4P connector
and ECM/PCM connector A (31P).
4. Connect ECM/PCM connector terminals A6 and A16
to body ground with a jumper wire.
5. Check for continuity between body ground and A/F
sensor (Sensor 1) 4P connector terminals No. 1 and
No. 2 individually.
Replace the A/F sensor (Sensor 1) (see page
11-279).
Repair open in the wire between the A/F
sensor (Sensor 1) and the ECM/PCM (A6 or A16).

A/F Sensor (Sensor 1) Circuit Out
of Range High
(2005-2006 models)
1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Start the engine. Hold the engine speed at
3,000 rpm without load (in Park or neutral) until the
radiator fan comes on, then let it idle.
4. Monitor the OBD STATUS for P1172 in the DTCs
MENU with the HDS.
Go to step 5.
If the screen indicates PASSED, intermittent
failure, 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.
5. Turn the ignition switch OFF.
6. Replace the A/F sensor (Sensor 1) (see page
11-279).
7. Turn the ignition switch ON (II).
8. Reset the ECM/PCM with the HDS.
9. Do the ECM/PCM idle learn procedure (see page
11-349).
10. Start the engine. Hold the engine speed at
3,000 rpm withtout load (in Park or neutral) until the
radiator fan comes on, then let it idle.
11. Check for Temporary DTCs or DTCs with the HDS.
If DTC P1172 is indicated, check for poor
connections or loose terminals at the A/F sensor
(Sensor 1) and the ECM/PCM, then go to step 1. If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting.
Go to step 12.
12. Monitor the OBD STATUS for DTC P1172 in the
DTCs MENU with the HDS.
Troubleshooting is complete.
If the screen indicates FAILED, check for poor
connections or loose terminals at the A/F sensor
(Sensor 1) and the ECM/PCM, then go to step 1. If
the screen indicates EXECUTING, keep driving until
a result comes on. If the screen indicates OUT OF
CONDITION, go to step 10 and recheck.
