DTC P0962: Line Pressure Linear Solenoid Valve System (Short circuit); DTC P0963: Line Pressure Linear Solenoid Valve System (Open circuit): Diagnosis
WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
- STEP 1. Check the TCM terminal voltage.
[TCM connector (harness side, connected)]
Measure the voltage between the PLLS terminal and body ground.
- While driving: 300 Hz
- Other than above: 0 V
Q: Is the check result normal?
- YES: Go to Step 5.
- NO: Go to Step 2.
- STEP 2. Check for continuity in PLLS line between the TCM connector and A/T control solenoid valve assembly connector.
When the continuity check result is OK, check that the wiring harness is not shorted to the body and other wiring harness.
Q: Is the check result normal?
- YES: Go to Step 3.
- NO: Repair the connector(s) or wiring harness.
- STEP 3. Check the line pressure linear solenoid.
Refer to A/T CONTROL RELAY CHECK .
Q: Is the check result normal?
- YES: Go to Step 6.
- NO: Go to Step 4.
- STEP 4. Check for continuity in signal line between the A/T control solenoid valve assembly connector and the line pressure linear solenoid valve connector.
Q: Is the check result satisfactory?
- YES: Replace the valve body assembly.
- NO: Repair the connector(s) or wiring harness.
- STEP 5. Check the TCMU and A/T control solenoid valve assembly connector pin terminals and the connection status.
Q: Is the check result normal?
- YES: Go to Step 7.
- NO: Repair or replace the failure section.
- STEP 6. Check the TCM and A/T control solenoid valve assembly connector pin terminals and the connection status.
Q: Is the check result normal?
- YES: Replace the TCM.
- NO: Repair or replace the failure section.
- STEP 7. Erase the DTC, and drive the vehicle for a while.
Check that the normal code is displayed.
Q: Is the check result normal?
- YES: The procedure is complete.
- NO: Return to Step 1.
