P0107

Wiring Diagram:

CIRCUIT DESCRIPTION
Refer to MAP Sensor Operation.

Detecting Condition / Possible Cause:

NOTE: When DTC P0107, P0122 and/or P0450 are indicated together, it is possible that "P/G" circuit is open.

DTC CONFIRMATION PROCEDURE
1. Clear DTC, start engine and keep it at idle for 1 min.
2. Select "DTC" mode on scan tool and check DTC.

Inspection (Steps 1 - 4):

MAP Sensor Individual Check




1. Disconnect coupler from MAP sensor.
2. Remove MAP sensor.

3. Arrange 3 new 1.5 V batteries in series (check that total voltage is 4.5- 5.0 V) and connect its positive terminal to "Vin" terminal of sensor and negative terminal to "Ground" terminal. Then check voltage between "Vout" and "Ground".
Also, check if voltage reduces when vacuum is applied up to 400 mmHg by using vacuum pump.

Output voltage (Vin voltage 4.5-5.5 V, ambient temp. 20-30 °C, 68-86 °F)




If check result is not satisfactory, replace MAP sensor.

4. Install MAP sensor securely.
5. Connect MAP sensor coupler securely.
