ECD SYSTEM, Diagnostic DTC:P0107, P0108

DTC Code DTC Name
P0107 Manifold Absolute Pressure / Barometric Pressure Circuit Low Input
P0108 Manifold Absolute Pressure / Barometric Pressure Circuit High Input

DESCRIPTION

B0024JOE08

The manifold absolute pressure sensor detects the intake manifold pressure. The ECM determines the basic injection volume and injection advance timing based on the voltage output by the manifold absolute pressure sensor.

The manifold absolute pressure sensor monitors the absolute pressure inside the intake manifold (default is 0 kPa [0 mmHg, 0 in.Hg]).

Tech Tips

Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


  1. READ VALUE USING GTS (MAP)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Enter the following menus: Powertrain / Engine and ECT / Data List / MAP.


      Powertrain > Engine and ECT > Data List
      Tester Display
      MAP

    4. Read the value.

      OK
      Same as the actual atmospheric pressure.

      Tech Tips


      • Standard atmospheric pressure is 101 kPa. For every 100 m increase in elevation, pressure drops by 1 kPa. This varies by weather (high atmospheric pressure, low atmospheric pressure).

      • Also, check "Atmosphere Pressure" in the Data List.
