Testing & Diagnostics ~420 words

Note. If DTC P0122, P0123, P1121, P1122, P0107, P0108, P1128, and/or P1129 are stored at the same time as DTC P2227, troubleshoot those DTCs first, then recheck for DTC P2227. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).

  1. Inspect the air cleaner element (see «AIR CLEANER REMOVAL/INSTALLATION»(ref-220574-S38222144532006022000000) ). Is there damage or clogging? YES- Replace the air cleaner element (see «AIR CLEANER ELEMENT INSPECTION/REPLACEMENT»(ref-220574-S16018447302006022000000) ). Clear the DTC with the HDS, then go to step 10 . NO- Go to step 2 .
  2. Turn the ignition switch ON (II), and wait 2 seconds.
  3. Check the BARO SENSOR in the DATA LIST with the HDS. Is it about 101 kPa (29.9 in.Hg, 760 mmHg), or about 2.9 V at sea level? YES- Go to step 4 . NO- Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM (see «ECM/PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-220569-S23624043112006022000000) ), then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM (see «MAP SENSOR REPLACEMENT»(ref-220570-S17955277902006022000000) ).
  4. Clear the DTC with the HDS.
  5. 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.
  6. Test-drive under these conditions: ECT SENSOR above 176°F (80°C) A/T in D position (M/T in 4th gear) TP SENSOR between 15° and 33° For 3 seconds
  7. Monitor the OBD STATUS for DTC P2227 in the DTCs MENU with the HDS. Does the screen indicate FAILED? YES- Go to step 8 . NO- If the screen indicates PASSED, intermittent failure, system is OK at this time. If the screen indicates NOT COMPLETED, go to step 5 and recheck.
  8. Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM (see «ECM/PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-220569-S23624043112006022000000) ).
  9. Reset the ECM/PCM with the HDS.
  10. Do the ECM/PCM idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(ref-220572-S08440202922006022000000) ).
  11. Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES- 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 . NO- If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see «MAP SENSOR REPLACEMENT»(ref-220570-S17955277902006022000000) ).
