ECD SYSTEM, Diagnostic DTC:35

DTC Code DTC Name
35 Turbo Pressure Sensor Circuit Malfunction

DESCRIPTION

The turbo pressure sensor is connected to the intake manifold. The ECM detects the intake manifold pressure as a voltage by the sensor. The ECM uses the intake manifold pressure signal for correction of injection volume control and injection timing control.

A01KGXXE01

The VSV for turbo pressure sensor switches the atmosphere applied to the turbo pressure sensor to the intake manifold pressure. The turbo pressure sensor monitors both the atmospheric pressure and intake manifold pressure and transmits the output voltage to the ECM, and the ECM uses this atmospheric pressure value for correcting the injection volume.

INSPECTION PROCEDURE

Tech Tips


  • If DTC Nos. 22, 24, 35 and 39 are output simultaneously, E2 (sensor ground) may be open.

  • Read freeze frame data using intelligent tester. Because freeze frame records the engine conditions when the malfunction is detected. When troubleshooting it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction.

  • When not using the intelligent tester go to step 12.

PROCEDURE


  1. READ VALUE OF INTELLIGENT TESTER (INTAKE MANIFOLD PRESSURE)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch ON and push the intelligent tester main switch ON.

    3. Read the value of the intake manifold pressure on the intelligent tester.

      Pressure
      Same as atmospheric pressure.
