DTC P2195: A/F Sensor (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 GENERAL TROUBLESHOOTING INFORMATION ).
  • If the vehicle was out of fuel and the engine stalled before this DTC was stored, refuel, then clear the DTC with the HDS.
  • If DTC P2101, P2118, P2135, P2138, P2176, or a combination of P2122 and P2127, P2122, and P2138, or P2127 and P2138 are stored at the same time, troubleshoot them first, then recheck for DTC P2195.
  1. Check the installation of the A/F sensor (Sensor 1).

    Is the A/F sensor loose or disconnected from the exhaust pipe? 

    YES  -Go to step  6.

    NO  -Go to step 2.

  2. Turn the ignition switch to ON (II).
  3. Clear the DTC with the HDS.
  4. Start the engine, and let it idle for 2 minutes.
  5. Check for Temporary DTCs or DTCs with the HDS.

    Is DTC P2195 indicated? 

    YES  -Check for poor connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM, then go to step  13.

    NO  -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 any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.

  6. Turn the ignition switch to LOCK (0).
  7. Reinstall the A/F sensor (Sensor 1) (see A/F SENSOR REPLACEMENT ).
  8. Turn the ignition switch to ON (II).
  9. Reset the ECM/PCM with the HDS.
  10. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).
  11. Check for Temporary DTCs or DTCs with the HDS.

    Is DTC P2195 indicated? 

    YES  -Check for poor connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM, then go to step  1.

    NO  -Go to step 12.

  12. Monitor the OBD STATUS for DTC P2195 in the DTCs MENU with the HDS.

    Does the screen indicate PASSED? 

    YES  -Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step  11, go to the indicated DTCs troubleshooting.

    NO  -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 indicated NOT COMPLETED, keep idling until a result comes on.

  13. Update the ECM/PCM if it does not have the latest software (see ECM/PCM UPDATE ), or substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).
  14. Start the engine, and let it idle for 2 minutes.
  15. Check for Temporary DTCs or DTCs with the HDS.

    Is DTC P2195 indicated? 

    YES  -Check for poor connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step  14. If the ECM/PCM was substituted, go to step  1.

    NO  -Go to step 16.

  16. Monitor the OBD STATUS for DTC P2195 in the DTCs MENU with the HDS.

    Does the screen indicate PASSED? 

    YES  -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or DTCs were indicated in step  15, go to the indicated DTCs troubleshooting.

    NO  -If the screen indicates FAILED, check for poor connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step  14. If the ECM/PCM was substituted, go to step  1. If the screen indicates NOT COMPLETED, keep idling until a result comes on.
