DESCRIPTION

Land Cruiser. Urj200, 202 Grj200 Vdj200.1Vd-Ftv Engine Control.Ecd System (W/ Dpf). Dtc P0105 Manifold Absolute Pressure / Barometric Pressure Circuit
The manifold absolute pressure sensor detects the intake manifold pressure by using its built-in sensor unit. The ECM determines the basic injection duration 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]). As a result the ECM controls the air-fuel ratio at the proper level under any driving conditions.

INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).
HINT:
  1. If DTCs relating to different systems are stored, and they share terminal E2 as their ground, check this ground circuit first.
  2. Read freeze frame data using the intelligent tester. 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.
1.READ VALUE USING INTELLIGENT TESTER (MANIFOLD ABSOLUTE PRESSURE)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

  1. Enter the following menus: Powertrain / Engine / Data List / MAP.

  1. Read the value.

    OK:
    Same value as the actual atmospheric pressure.
    HINT:
    Standard atmospheric pressure is 101 kPa. For every 100 m increase in altitude, pressure drops by 1 kPa. Varies by weather (high atmospheric pressure, low atmospheric pressure).


OK
