Note. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).

  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 (in P or N) until the radiator fan comes on, then let it idle.
  4. Check under these DATA LIST parameters with the HDS: ECT SENSOR 1 above 156°F (70°C) IAT SENSOR above 32°F (0°C) VEHICLE SPEED is 0 mph (0 km/h) ST FUEL TRIM between 0.75-1.47 FSS is CLOSED
  5. Monitor the OBD STATUS for DTC P0506 in the DTCs MENU with the HDS. Does the HDS indicate FAILED? YES -Go to step 6. NO -If the HDS indicates PASSED, go to step 15 . If the HDS indicates EXECUTING, keep idling until a result comes on. If the HDS indicates OUT OF CONDITION, go to step 4 and recheck.
  6. Remove the air cleaner (see «AIR CLEANER REMOVAL/INSTALLATION»(ref-513163-S20686336082012110700000) ).
  7. Check for dirt, carbon, or damage in the throttle bore. Is there dirt, carbon, or damage in the throttle bore? YES -If there is dirt or carbon, clean the throttle body (see «THROTTLE BODY TEST»(ref-513163-S00568422612012110700000) ). Also check for damage to the air cleaner element (see «AIR CLEANER ELEMENT INSPECTION/REPLACEMENT»(ref-513163-S39791316032012110700000) ), then go to step 9 . If there is damage in the throttle bore, go to step 8. NO -Check the A/C system and the power steering system, then go to step 17 .
  8. Replace the throttle body (see «THROTTLE BODY REMOVAL/INSTALLATION»(ref-513163-S12903280352012110700000) ).
  9. Reset the PCM with the HDS.
  10. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-513173-S16164063582012110700000) ).
  11. Start the engine. Hold the engine speed at 3, 000 rpm without load (in P or N) until the radiator fan comes on, then let it idle.
  12. Check under these DATA LIST parameters with the HDS: ECT SENSOR 1 above 156°F (70°C) IAT SENSOR above 32°F (0°C) VEHICLE SPEED is 0 mph (0 km/h) ST FUEL TRIM between 0.75-1.47 FSS is CLOSED
  13. Check for Pending or Confirmed DTCs or DTCs with the HDS. Is DTC P0506 indicated? YES -Check the A/C system and/or the power steering system, then go to step 1 . NO -Go to step 14.
  14. Monitor the OBD STATUS for DTC P0506 in the DTCs MENU with the HDS. Does the HDS indicate PASSED? YES -Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated in step 13 , go to the indicated «DTC'S TROUBLESHOOTING»(ref-513173-S01024518172012110700000) . NO -If the HDS indicates FAILED, check the A/C system and/or the power steering system, then go to step 1 . If the HDS indicates EXECUTING, keep idling until a result comes on. If the HDS indicates OUT OF CONDITION, go to step 11 .
  15. Remove the air cleaner (see «AIR CLEANER REMOVAL/INSTALLATION»(ref-513163-S20686336082012110700000) ).
  16. Check for dirt, carbon, or damage in the throttle bore. Is there dirt, carbon, or damage in the throttle bore? YES -If there is dirt or carbon, clean the throttle body (see «THROTTLE BODY TEST»(ref-513163-S00568422612012110700000) ). Also check for damage to the air cleaner element (see «AIR CLEANER ELEMENT INSPECTION/REPLACEMENT»(ref-513163-S39791316032012110700000) ), then go to step 9 . If there is damage in the throttle bore, go to step 8 . NO -Go to step 17.
  17. Recheck with different load conditions (turn on the headlights, the blower motor, the rear window defogger, and/or the A/C, change the gear position, etc.).
  18. Monitor the OBD STATUS for DTC P0506 in the DTCs MENU with the HDS. Does the HDS indicate PASSED? YES -Intermittent failure, the system is OK at this time. NO -If the HDS indicates FAILED, check the A/C system and/or power steering system, then go to step 1 and recheck. If the HDS indicates EXECUTING, keep idling until a result comes on. If the HDS indicates OUT OF CONDITION, go to step 11 .

Note. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).

  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 (in P or N) until the radiator fan comes on, then let it idle for at least 20 seconds.
  4. Monitor the OBD STATUS for DTC P0507 in the DTCs MENU with the HDS. Does the HDS indicate FAILED? YES -Go to step 5. NO -If the HDS indicates PASSED, intermittent failure, the system is OK at this time. If the HDS indicates EXECUTING, keep idling until a result comes on.
