DIAGNOSIS PROCEDURE


STEP 1. M.U.T.-III data list



  • Data list reference table (Refer to ).

  1. Item 8: Manifold absolute pressure sensor

Q. Is the check result normal?

Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Go to Step 2.

STEP 2. Perform resistance measurement at manifold absolute pressure sensor connector.



  • Disconnect connector, and measure at harness side.
  • Resistance between terminal engine-ECU MAPE line and body earth.
OK: Continuity (2 Ω or less)

Q. Is the check result normal?

Go to Step 5.
Go to Step 3.

STEP 3. Check harness between manifold absolute pressure sensor connector terminal and engine-ECU connector terminal MAPE.



  • Check earthing line for open circuit and damage.

Q. Is the check result normal?

Go to Step 4.
Repair or replace the connector, or repair the damaged harness wire.

STEP 4. M.U.T.-III data list



  • Data list reference table (Refer to ).

  1. Item 8: Manifold absolute pressure sensor

Q. Is the check result normal?

Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Replace the engine-ECU.

STEP 5. M.U.T.-III data list



  • Data list reference table (Refer to ).

  1. Item 8: Manifold absolute pressure sensor

Q. Is the check result normal?

Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Go to Step 6.

STEP 6. Replace the manifold absolute pressure sensor



  • After replacing the manifold absolute pressure sensor, reconfirm whether the diagnosis code is stored.

Q. Is the diagnosis code stored?

Replace the engine-ECU.
Check end.
