What are the common causes of P0779 ?

Several problems may cause a P0779 code including:

• Low transmission fluid
• Dirty or contaminated transmission fluid
• Damaged or defective electronic pressure control solenoid
• Hydraulic blockage inside transmission fluid passages
• Transmission failure
• Damaged or defective transmission control module
• Damaged or defective ECM (rare)

How do you troubleshoot P0779 ?

Replace the oxygen sensor that is downstream from the catalytic converter on the side of the engine that does not contain cylinder #1. Also, if a oxygen sensor code stating "heater circuit malfunction" the sensor has most probably failed. With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground. Look for rubbing, scraping, bare wires, worn spots or melted plastic connectors. Pull the connectors apart and carefully look at the terminals (the metal parts) inside the connectors.
