DTC Troubleshooting (cont’d)

A/F Sensor (Sensor 1) Signal

Stuck Lean
(2005-2006 models)

NOTE: If the vehicle was out of fuel and the engine
stalled before this DTC was stored, refuel and clear the
DTC with the HDS.

1. Inspect the condition of the A/F sensor (Sensor 1).

Go to step 2.

Go to step 4.

2. Turn the ignition switch OFF.

3. Reinstall the A/F sensor (Sensor 1) (see page

11-279).

4. Turn the ignition switch ON (II).

5. Reset the ECM/PCM with the HDS.

6. Do the ECM/PCM idle learn procedure (see page

11-349).

7. Check for Temporary DTCs or DTCs with the HDS.

If DTC P2195 is indicated, check for poor

connections or loose terminals at the A/F sensor
(Sensor 1) and the ECM/PCM. If the connection and
terminal fits are OK, go to step 8. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

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.

8. Monitor the OBD STATUS for DTC P2195 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 2. If
the screen indicates NOT COMPLETED, go to step 5
and recheck.

Is it loose in the exhaust pipe?

Ar e any T empor ar y DT Cs or DT Cs indicated?

Does the scr een indicate PASSED?

BARO Sensor Circuit Range/

Performance Problem
(2005-2006 models)

NOTE: If DTC P0107, P0108, P1128 and/or P1129 are
stored at the same time as DTC P2227, troubleshoot
those DTCs first, then recheck for DTC P2227.

1. Turn the ignition switch ON (II), and wait 2 seconds.

2. Check the BARO SENSOR in the DATA LIST with

the HDS.

Go to step 3.

Update the ECM/PCM if it does not have the

latest software, or substitute a known-good ECM/
PCM (see page 11-6), then recheck. If the symptom/
indication goes away with a known-good ECM/PCM,
replace the original ECM/PCM (see page 11-284).

3. Clear the DTC with the HDS.

4. 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.

5. Test-drive under these conditions, then connect the

HDS.

• Engine coolant temperature above 158 °F (70 °C)
• A/T in D position (M/T in 4th gear)
• Throttle position between 12 degrees and

20 degrees for 2 seconds

6. Monitor the OBD STATUS for DTC P2227 in the

DTCs MENU with the HDS.

Go to step 7.

If the screen indicates PASSED, intermittent

failure, system is OK at this time. If the screen
indicates NOT COMPLETED, go to step 4 and
recheck.

7. Update the ECM/PCM if it does not have the latest

software, or substitute a known-good ECM/PCM
(see page 11-6).

8. Reset the ECM/PCM with the HDS.

9. Do the ECM/PCM idle learn procedure (see page

11-349).

10. Check for Temporary DTCs or DTCs with the HDS.

If DTC P2227 is indicated, check for poor

connections or loose terminals at the ECM/PCM,
then go to step 1. If any other Temporary DTCs or
DTCs are indicated, go to the indicated DTC’s
troubleshooting.

If the ECM/PCM was updated, troubleshooting

is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-284).

Is about 101 kPa ( 29.9 in.Hg, 7 60 mmHg), or about
2.9 V at sea level indicated?

Does the scr een indicate F AILED?

Ar e any T empor ar y DT Cs or DT Cs indicated?
