DTC P0106 Manifold Absolute Pressure / Barometric Pressure Circuit Range / Performance Problem

DESCRIPTION

The manifold absolute pressure sensor detects the intake manifold pressure by using the 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.


Dtc P0106  Manifold Absolute Pressure / Barometric Pressure Circuit Range / Performance Problem. 2AD-FHV ENGINE CONTROL SYSTEM. Lexus IS250 IS220d GSE20 ALE20

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

INSPECTION PROCEDURE

  • HINT:
  • If DTCs P0105, P0107, and P0108 are output simultaneously, the manifold absolute pressure sensor circuit may have an open or short. Perform troubleshooting for those DTCs first.
1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0106)

Connect the intelligent tester to the DLC3.

Turn the engine switch ON (IG) and turn the intelligent tester ON.

Enter the following menus: "Powertrain / Engine / DTC".

Read DTCs.

  • Result:
  • Display (DTC output)Proceed to
    P0106A
    P0106 and other DTCsB
  • HINT:
  • If codes other than P0106 are output, perform troubleshooting for those DTCs first.
