  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 inHg, 760 mmHg), or about 2.9 V at sea level indicated? YES -Go to step 3. NO -Go to step 7 .
  3. Clear the DTC with the HDS.
  4. 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.
  5. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C) Transmission in D REL TP SENSOR between 12 degrees and 20 degrees for 3 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. Update the PCM if it does not have the latest software (see «PCM Update»(ref-371341-S07894970022010091000000) ), or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-371340-S22381000502010091000000) ).

  9. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C) Transmission in D REL TP SENSOR between 12 degrees and 20 degrees for 3 seconds
  10. Check for Pending or Confirmed DTCs with the HDS. Is DTC P2227 indicated? YES -Check for poor connections or loose terminals at the PCM. If the PCM was updated, substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-371340-S22381000502010091000000) ), then Go to step 8 . If the PCM was substituted, Go to step 1 . NO -Go to step 11.
  11. Monitor the OBD STATUS for DTC P2227 in the DTCs MENU with the HDS. Does the screen indicate PASSED? YES -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see «PCM REPLACEMENT»(ref-371341-S08888649802010091000000) ). If any other Pending or Confirmed DTCs were indicated in step 10, go to the indicated DTC's troubleshooting. NO -If the screen indicates FAILED, check for poor connections or loose terminals at the PCM. If the PCM was updated, substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-371340-S22381000502010091000000) ), then Go to step 10 . If the PCM was substituted, Go to step 1 .
