DTC P2089

Oil control valve (OCV) circuit high

DETECTION CONDITION

• The PCM monitors the OCV voltage. If the PCM detects that the OCV control voltage (calculated from the OCV) is above the threshold voltage (calculated from battery positive voltage), the PCM determines that the OCV circuit has a malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
• PENDING CODE is available if the PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• Are any DTCs is stored in the PCM memory.

POSSIBLE CAUSE

• Poor connection at the PCM or OCV connector
• Short to power circuit in wiring between OCV terminal A and PCM terminal 2E
• OCV malfunction
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Verify related Service Information availability.
• Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service information.
If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT OCV CONNECTOR FOR POOR CONNECTION
• Turn the ignition switch off.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 7.
No
Go to the next step.
4
INSPECT OCV
• Inspect the OCV.
• Is the OCV normal?
Yes
Go to the next step.
No
Replace the OCV, then go to Step 7.
5
INSPECT PCM CONNECTOR FOR POOR CONNECTION
• Turn the ignition switch off.
• Disconnect the PCM connector.
• Inspect for poor connection at PCM terminal 2E (such as damaged, pulled-out pins, corrosion).
• Is there malfunction?
Yes
Repair the terminal, then go to Step 7.
No
Go to the next step.
6
INSPECT OCV CONTROL CIRCUIT FOR SHORT TO POWER
• Remove the OCV.
• Turn the ignition switch to the ON position (Engine off).
• Measure the voltage between PCM terminal 2E and body ground.
• Is the voltage B+?
Yes
Repair or replace the wiring harness for short to power supply, then go to the next step.
No
Go to the next step.
7
VERIFY TROUBLESHOOTING OF DTC P2089 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Turn the ignition switch off.
• Start the engine and warm it up completely.
• Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
• Perform the "AFTER REPAIR PROCEDURE".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
