DESCRIPTION

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, and fuel control accuracy is not influenced by fluctuations in the atmospheric pressure due to factors such as high altitude, etc.

DTC No.

INSPECTION PROCEDURE

ПРИМЕЧАНИЕ:
After replacing the ECM, the new ECM needs registration (see page RAV4_ACA30 RM000000TJ400AX.html) and initialization (see page RAV4_ACA30 RM000000TIN009X.html).
УКАЗАНИЕ:
If DTCs relating to different systems are output, and they share terminal E2 as their ground, check this ground circuit first.
1.READ VALUE OF MANIFOLD ABSOLUTE PRESSURE SENSOR

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG) and turn the tester ON.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / MAP and Atmosphere Pressure.

  1. Read the value.

    OK:
    Condition
    		MAP Value
    No pressure applied
    		Same as atmospheric pressure
    Vacuum applied
    		Becomes vacuum
    Pressure applied
    		Becomes pressurized
