ECD SYSTEM, Diagnostic DTC:35

DTC Code DTC Name
35 Manifold Absolute Pressure / Barometric Pressure Circuit Malfunction

DESCRIPTION

The manifold absolute pressure sensor generates voltage by the vacuum value as shown in the illustration. This voltage of the manifold absolute pressure sensor is one of the factors to decide the injection volume and injection timing.

INSPECTION PROCEDURE

Tech Tips


  • If different DTCs that are related to different systems are output simultaneously while terminal E2 is used as a ground terminal, terminal E2 may be open.

  • Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air/fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

When using intelligent tester:

PROCEDURE


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


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch ON.

    3. Select the item "Powertrain/Engine and ECT/Data List/PIM" and read its value displayed on the intelligent tester.

      OK
      The same as atmospheric pressure.

      Tech Tips

      When DTC 35 is present, check the manifold absolute pressure by selecting "Powertrain/Engine and ECT/ Data List/PIM" on the intelligent tester.

  2. CHECK CONNECTION OF VACUUM HOSE


    1. Check that the vacuum hose is securely connected and no leaks from the connection.

      OK
      The vacuum hose is securely connected and there are no leaks from the connection.

    NG

    REPAIR OR REPLACE VACUUM HOSE

    OK
