DTC P2227: BARO Sensor Circuit Range/Performance Problem Honda Crosstour I

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, P0121 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 HAS. Is about 101 kPa (29.9 inHg, 760 mmHg), or about 2.9 V at sea level indicated? YES -Go to next step. NO -Go to step 7 .
  3. Clear the DTC with the HAS.
  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 Throttle position between 14 and 29 degrees for at least 3 seconds
  6. Monitor the OBD STATUS for DTC P2227 in the DTCs MENU with the HAS. Does the HAS indicate FAILED? YES -Go to next step. NO -If the HAS indicates PASSED, intermittent failure, the system is OK at this time. If the HAS 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 next step.
  8. Update the PCM if it does not have the latest software (see «PCM UPDATE»(ref-360080-S11980508702010042600000) (+) or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-360056-S32194616542010042600000) (+).
  9. 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.
  10. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C) Transmission in D Throttle position between 14 and 29 degrees for at least 3 seconds
  11. Check for Pending or Confirmed DTCs with the HAS. 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-360056-S32194616542010042600000) (+) then go to step 9 . If the PCM was substituted, go to step 1 . NO -Go to next step.
  12. Monitor the OBD STATUS for DTC P2227 in the DTCs MENU with the HAS. Does the HAS indicate PASSED? YES -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see «PCM REPLACEMENT»(ref-360080-S27881728262010042600000) (+). If any other Pending or Confirmed DTCs were indicated in step 11 , go to the indicated DTC's troubleshooting. NO -If the HAS 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-360056-S32194616542010042600000) (+) then go to step 9 . If the PCM was substituted, go to step 1 . If the HAS indicates NOT COMPLETED, go to step 9 .
