Note. 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.

Turn the ignition switch ON (II), and wait 2 seconds.
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 - Update the PCM if it does not have the latest software, or substitute a known-good PCM (see «PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-220945-S16531944742006022100000) ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM (see «PCM REPLACEMENT»(ref-220946-S32339521312006022100000) ).
Clear the DTC with the HDS.
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.
Test-drive under these conditions: Engine coolant temperature above 158°F (70°C) A/T in D position Throttle position between 14 degrees and 45 degrees for 2 seconds
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, system is OK at this time. If the screen indicates NOT COMPLETED, go to step 4 and recheck.
Update the PCM if it does not have the latest software, or substitute a known-good PCM (see «PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-220945-S16531944742006022100000) ).
Reset the PCM with the HDS.
Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-220951-S17680691112006022100000) ).
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 PCM, then go to step 1 . If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting. NO - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see «PCM REPLACEMENT»(ref-220946-S32339521312006022100000) ).
