- Turn the ignition switch to ON (II).
- Check the MAP SENSOR in the DATA LIST with the HDS. Is about 3 kPa (1.0in. Hg, 26 mmHg), or 0.23 V or less indicated? YES -Go to step 3. NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the MAP sensor and the PCM.
- Turn the ignition switch to LOCK (0).
- Disconnect the MAP sensor 3P connector.
- Turn the ignition switch to ON (II).
- Check the MAP SENSOR in the DATA LIST with the HDS. Is about 3 kPa (1.0 in.Hg, 26 mmHg), or 0.23 V or less indicated? YES -Go to step 12 . NO -Go to step 7.
- Measure the voltage between MAP sensor 3P connector terminals No. 1 and No. 3. Is there about 5 V? YES -Go to step 16 . NO -Go to step 8.
- Turn the ignition switch to LOCK (0).
- Jump the SCS line with the HDS.
- Disconnect PCM connector B (49P).
- Check for continuity between PCM connector terminal B36 and MAP sensor 3P connector terminal No. 1. Is there continuity? YES -Go to step 23 . NO -Repair open in the wire between the PCM (B36) and the MAP sensor, then Go to step 18 .
- Turn the ignition switch to LOCK (0).
- Jump the SCS line with the HDS.
- Disconnect PCM connector B (49P).
- Check for continuity between MAP sensor 3P connector terminal No. 2 and body ground. Is there continuity? YES -Repair short in the wire between the PCM (B35) and the MAP sensor, then Go to step 18 . NO -Go to step 23 .
- Turn the ignition switch to LOCK (0).
- Replace the MAP sensor (see «MAF SENSOR/IAT SENSOR REPLACEMENT»(ref-336453-S25816260512009072700000) ).
- Reconnect all connectors.
- Turn the ignition switch to ON (II).
- Reset the PCM with the HDS.
- Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-336473-S09468920992009072700000) ).
- Check for Pending DTCs or Confirmed DTCs with the HDS. Is DTC P0107 indicated? YES -Check for poor connections or loose terminals at the MAP sensor and the PCM, then Go to step 1 . NO -Troubleshooting is complete. If any other Pending DTCs or Confirmed DTCs are indicated, Go to the indicated DTC's troubleshooting.
- Reconnect all connectors.
- Update the PCM if it does not have the latest software (see «PCM UPDATE»(ref-336453-S09500398002009072700000) ), or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-336452-S17145915352009072700000) ).
- Check for Pending DTCs or Confirmed DTCs with the HDS. Is DTC P0107 indicated? YES -Check for poor connections or loose terminals at the MAP sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-336452-S17145915352009072700000) ), then recheck. If the PCM was substituted, Go to step 1 . NO -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see «PCM REPLACEMENT»(ref-336453-S28620960052009072700000) ). If any other Pending DTCs or Confirmed DTCs are indicated, Go to the indicated DTC's troubleshooting.
