Code No. P0841: Abnormality in Line Pressure Sensor Function


DIAGNOSTIC FUNCTION


CVT-ECU conducts fault detection by comparing the target line pressure reading with the actual secondary pressure reading.

JUDGEMENT CRITERIA


The actual secondary pressure reading is 0.675 MPa or more, and the status over the target line pressure remains for 5 seconds.

PROBABLE CAUSES



DIAGNOSTIC PROCEDURE

STEP 1. Check other diagnosis codes.

Q. Are other diagnosis codes set?
Go to the appropriate troubleshooting.
Go to Step 2.

STEP 2. Line pressure check
Carry out "hydraulic test"(Refer to ).

Q. Is the check result normal?
Go to Step 3.
Repair according to the hydraulic pressure diagnosis table.

STEP 3. Symptom recheck after erasing diagnosis code

Q. Is the check result normal?
Intermittent malfunction
Replace CVT-ECU.
