DTC Troubleshooting: P0107 (3)

DTC P0107:  MAP Sensor Circuit Low Voltage


NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.

1.Turn the ignition switch ON (II).

2.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 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.n


3.Turn the ignition switch OFF.

4.Disconnect the MAP sensor 3P connector.

5.Turn the ignition switch ON (II).

6.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 12.


NO - Go to 7.


7.Measure voltage between MAP sensor 3P connector terminals No. 1 and No. 3.

 

Is there about 5 V?


YES - Go to 16.


NO - Go to 8.


8.Turn the ignition switch OFF.

9.Jump the SCS line with the HDS.

10.Disconnect ECM/PCM connector C (44P).

11.Check for continuity between ECM/PCM connector terminal C13 and MAP sensor 3P connector terminal No. 1.

 

Is there continuity?


YES - Go to 23.


NO - Repair open in the wire between the ECM/PCM (C13) and the MAP sensor, then go to 18.

12.Turn the ignition switch OFF.

13.Jump the SCS line with the HDS.

14.Disconnect ECM/PCM connector C (44P).

15.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 (C11) and the MAP sensor, then go to 18.


NO - Go to 23.

16.Turn the ignition switch OFF.

17.Replace the MAP sensor.

18.Reconnect all connectors.

19.Turn the ignition switch ON (II).

20.Reset the ECM/PCM with the HDS.

21.Do the ECM/PCM idle learn procedure.

22.Check for Temporary DTCs or DTCs 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 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.


NO - Troubleshooting is complete.n


23.Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM.

24.Check for Temporary DTCs or DTCs 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 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.n
