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. Resistance measurement at manifold absolute pressure sensor connector (MAPE line).


(1)Disconnect the connector, and measure at the wiring harness side.
(2)Check the resistance between the manifold absolute pressure sensor connector (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 of open circuit in MAPE line between manifold absolute pressure sensor connector and engine-ECU connector.


Q. Is the check result normal?

Go to Step 4.
Repair the connector(s) or wiring harness.

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 diagnosis code



  • Reconfirmation of diagnosis code.

Q. Is the diagnosis code stored?

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

STEP 6. Replace the manifold absolute pressure sensor



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

Q. Is diagnosis code stored?

Replace the engine-ECU.
Check end.
