Sensor 1) Signal Stuck Lean

NOTE:

• Before you troubleshoot, record all freeze data and

any on-board snapshot, and review the general
troubleshooting information (see page 11-3).

• Information marked with an asterisk ( ) applies to the

front bank (Bank 2).

• If the vehicle was out of fuel and the engine stalled

before this DTC was stored, refuel, and clear the DTC
with the HDS.

• If DTC P2101, P2108, P2118, P2135, P2176, U0107, or

a combination of P2122 and P2127, P2122 and P2138
or P2127 and P2138 is stored at the same time as DTC
P2195 (P2197) , troubleshoot those DTCs first, then
recheck for DTC P2195 (P2197) .

1. Check the installation of the A/F sensor (Sensor 1).

Go to step 6.

Go to step 2.

2. Turn the ignition switch ON (II).

3. Clear the DTC with the HDS.

4. Start the engine, then let it idle.

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

Check for poor connections or loose

terminals at the A/F sensor (Sensor 1) and the PCM,
then go to step 13.

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 PCM. If any
other Temporary DTCs or DTCs are indicated, go to
the indicated DTC’s troubleshooting.

6. Turn the ignition switch OFF.

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

11-199).

8. Turn the ignition switch ON (II).

9. Reset the PCM with the HDS.

10. Do the PCM idle learn procedure (see page 11-273).

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

Check for poor connections or loose

terminals at the A/F sensor (Sensor 1) and the PCM,
then go to step 1.

Go to step 12.

12. Monitor the OBD STATUS for DTC P2195 and/or

P2197 in the DTCs MENU with the HDS.

Troubleshooting is complete. If any other

Temporary DTCs or DTCs were indicated in step 11,
go to the indicated DTC’s troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at A/F sensor
(Sensor 1) and the PCM, then go to step 1. If the
screen indicates NOT COMPLETED, keep idling
until a result comes on.
