DTC Troubleshooting: P0107 (3)

DTC P0107: MAP Sensor Circuit Low Voltage Turn the ignition switch ON (II). Check the MAP SENSOR in the DATA LIST with the HDS. Is about 3 kPa (26 mmHg, 1.0 in.Hg), or 0.23 V or less indicated?
YES | - | Go to Step 3 .
NO | - | Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the MAP sensor and the ECM/PCM.■
Turn the ignition switch OFF. Disconnect the MAP sensor 3P connector. Turn the ignition switch ON (II). Check the MAP SENSOR in the DATA LIST with the HDS. Is about 3 kPa (26 mmHg, 1.0 in.Hg), or 0.23 V or less indicated?
YES | - | Go to Step 9 .
NO | - | Go to Step 7 .
Measure voltage between MAP sensor 3P connector terminals No. 1 and No. 3. Is there about 5 V?
YES | - | Go to Step 13 .
NO | - | Go to Step 8 .

Measure voltage between ECM/PCM connector terminals A21 and A24. Is there about 5 V?
YES | - | Repair open in the wire between the ECM/PCM (A21) and the MAP sensor, then go to Step 15 .
NO | - | Go to Step 19 .
Turn the ignition switch OFF. Jump the SCS line with the HDS. Disconnect ECM/PCM connector A (31P). |

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 ECM/PCM (A30) and the MAP sensor, then go to Step 15 .
NO | - | Go to Step 19 .
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 in the DTCs MENU with the HDS. Are any Temporary DTCs or DTCs indicated?
YES | - | If DTC P0107 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 in the DTCs MENU with the HDS. Are any Temporary DTCs or DTCs indicated?
YES | - | If DTC P0107 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. ■
