DTC P0107: MAP SENSOR CIRCUIT LOW VOLTAGE

1. Turn the ignition switch ON (II).

2. Check the MAP SENSOR in the DATA LIST with the HDS.

Is about 3 kPa (26 mm Hg, 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.

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 mm Hg, 1.0 in. Hg), or 0.23 V or less indicated?

YES: Go to step 9 .

NO: Go to step 7.

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.
