P0765

TECHNICAL DESCRIPTION
- When a malfunction of the shift solenoid D (overdrive solenoid) is detected, the transaxle control CPU inside the powertrain control module (PCM) outputs a malfunction signal to the engine control CPU in the PCM.

DTC SET CONDITIONS

Check Conditions, Judgment Criteria
- Overdrive solenoid failure signal is input to the engine control CPU from the transaxle control CPU.

TROUBLESHOOTING HINTS
The most likely causes for this code to be set are:
- Overdrive solenoid failed.
- Open or shorted overdrive solenoid circuit, or loose connector.
- PCM failed.

DIAGNOSIS
Required Special Tool:
MB991502: Scan Tool (MUT-II)

CAUTION: To prevent damage to scan tool MB991502, always turn the ignition switch to "LOCK" (OFF) position before connecting or disconnecting scan tool MB991502.




STEP 1. Using scan tool MB991502, read the A/T diagnostic trouble code (DTC).
1. Connect scan tool MB991502 to the data link connector.
2. Turn the ignition switch to "ON" position.
3. Read the A/T DTC.

If the A/T-DTC is displayed, refer to Automatic Transaxle Diagnosis - Trouble Code Descriptions Chart. Testing and Inspection

If the A/T-DTC is not displayed, it is suspected that an MFI-DTC has not been erased after repairing the A/T component.

If DTC P0765 is displayed again after the MFI-DTC has been erased, replace the PCM.

Then check that the DTC P0765 does not reset.
