Code P0796 2016 Toyota RAV4 Description

The OBD-II trouble code P0796 in a 2016 Toyota RAV4 indicates an issue with the Pressure Control Solenoid 'C' in the transmission. This solenoid is responsible for regulating the hydraulic pressure within the transmission, which is crucial for proper gear shifting and overall transmission performance. When the PCM (Powertrain Control Module) detects that the actual performance of the Pressure Control Solenoid 'C' does not match the expected parameters, it triggers this code.

Tech Notes for P0796 2016 Toyota RAV4

When a transmission solenoid malfunction, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is dirty, it's recommended to change the transmission fluid and if possible, remove the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure, and that the transmission will need to be rebuilt or replaced.
