Connect ECM/PCM connector terminals A24 and A30 with a jumper wire. Turn the ignition switch ON (II). Check the MAP SENSOR in the DATA LIST with the HDS. Is 160 kPa (1,197 mmHg, 47.1 in.Hg), 4.49 V or more indicated?
YES | - | Go to Step 26 .
NO | - | Repair open in the wire between the ECM/PCM (A30) and the MAP sensor, then go to Step 21 .
Turn the ignition switch OFF. Replace the MAP sensor. Reconnect all connectors. Turn the ignition switch ON (II). Reset the ECM/PCM with the HDS. Do the ECM/PCM idle learn procedure. Check for Temporary DTCs or DTCs with HDS. Are any Temporary DTCs or DTCs indicated?
YES | - | If DTC P0108 is indicated, check for poor connections or loose terminals at the MAP sensor and the ECM/PCM, then go to Step 1 . If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
NO | - | Troubleshooting is complete.■
Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM. Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated?
YES | - | If DTC P0108 is indicated, check for poor connections or loose terminals at the MAP sensor and the ECM/PCM, then go to Step 1 . If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
NO | - | If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM. ■
