Testing & Diagnostics ~523 words

Note. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ). 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 to ON (II), and wait 2 seconds.
  2. Check the BARO SENSOR in the DATA LIST with the HDS. Is about 101 kPa (29.9 in.Hg, 760 mmHg), or about 2.9 V at sea level indicated? YES -Go to step 3. NO -Go to step 8 .
  3. Clear the DTC with the HDS.
  4. Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in neutral) until the radiator fan comes on, then let it idle.
  5. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C) A/T in D, M/T in 4th REL TP SENSOR between 12 deg and 20 deg for 5 seconds
  6. Monitor the OBD STATUS for DTC P2227 in the DTCs MENU with the HDS. Does the screen indicate FAILED? YES -Go to step 7. NO -If the screen indicates PASSED, intermittent failure, the system is OK at this time. If the screen indicates NOT COMPLETED, go to step 4 and recheck.
  7. Check the intake air system for clogging or restrictions (foreign material, dirty air cleaner element,etc.) Is the intake air system clogged or restricted? YES -Remove the clog or restriction,then go to step 9. NO -Go to step 8.
  8. Update the ECM/PCM if it does not have the latest software (see «ECM/PCM UPDATE»(ref-355126-S21746322412010012000000) ), or substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-379879-S00676494072010121600000) ).
  9. Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in neutral) until the radiator fan comes on, then let it idle.
  10. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C) A/T in D, M/T in 4th REL TP SENSOR between 12 deg and 20 deg for 5 seconds
  11. Check for Pending or Confirmed DTCs with the HDS. Is DTC P2227 indicated? YES -Check for poor connections or loose terminals at the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-379879-S00676494072010121600000) ), then go to step 9 . If the ECM/PCM was substituted, go to step 1 . NO -Go to step 12.
  12. Monitor the OBD STATUS for DTC P2227 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»(ref-355126-S35548339322010012000000) ). If any other Pending or Confirmed DTCs were indicated in step 11 , go to the «INDICATED DTC'S TROUBLESHOOTING»(ref-355126-S38482784232010012000000) . NO -If the screen indicates FAILED, check for poor connections or loose terminals at the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-379879-S00676494072010121600000) ), then go to step 9 . If the ECM/PCM was substituted, go to step 1 . If the screen indicates NOT COMPLETED, go to step 9 .
