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

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 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 7 .
3. Clear the DTC with the HDS.
4. 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.
5. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C) Transmission in D position REL TP SENSOR between 14deg and 28deg 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 «UPDATING THE PCM»(ref-243311-S19790429062006082300000) ), or substitute a known-good PCM (see «HOW TO SUBSTITUTE THE PCM»(ref-243311-S24543735662006082300000) ).
8. 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.
9. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C) Transmission in D position REL TP SENSOR between 14° deg and 28° deg for 3 seconds
10. Check for Temporary DTCs or 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 «HOW TO SUBSTITUTE THE PCM»(ref-243311-S24543735662006082300000) ), 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-298125-S08727755362008091500000) ). If any other Temporary DTCs or 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 «HOW TO SUBSTITUTE THE PCM»(ref-243311-S24543735662006082300000) ), then go to step 8 . If the PCM was substituted, go to step 1 . If the screen indicates NOT COMPLETED, go to step 8 .
