P0107

Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Low

Short to ground in air pressure sensor assembly circuit.

  • Air pressure sensor assembly

  • Wire harness or connector

  • ECM

Comes on

DTC stored

P0108

Manifold Absolute Pressure / Barometric Pressure Sensor Circuit High

Short to +B in air pressure sensor assembly circuit.

  • Air pressure sensor assembly

  • Wire harness or connector

  • ECM

Comes on

MONITOR DESCRIPTION

These DTCs are stored when a malfunction is detected in the air pressure sensor assembly circuit. If there is an open or short in the air pressure sensor assembly circuit when the ignition switch is turned to ON, the ECM will illuminate the MIL and store a DTC.

PROCEDURE

  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0107 AND/OR P0108)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Trouble Codes.

    5. Check for DTCs.

      Powertrain > Engine > Trouble Codes

      DTC P0107 and/or P0108 and other DTCs are output

      B

      Tip:

      If DTC P0107 and/or P0108 and P0562, P0563 or P0658 are output simultaneously, troubleshoot for DTC P0562, P0563 or P0658 first.

  2. READ VALUE USING GTS (MEASURING OF THE INLET PRESSURE)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Data List / Measuring of the Inlet Pressure.

      Powertrain > Engine > Data List

      Idling with warm engine

      20 to 40 kPa

    Tip:
    • Standard atmospheric pressure is 101 kPa(abs) [758 mmHg(abs)]. For every 100 m (328 ft.) increase in altitude, atmospheric pressure drops by approximately 1 kPa (7.5 mmHg). The pressure also varies due to the weather (high atmospheric pressure, low atmospheric pressure).

    • Check "Atmospheric Pressure" in the Data List.

  3. CHECK HARNESS AND CONNECTOR (AIR PRESSURE SENSOR ASSEMBLY - ECM)

    1. Disconnect the air pressure sensor assembly connector.

    2. Disconnect the ECM connector.

    3. Measure the resistance according to the value(s) in the table below.
