The P0785 fault code refers to a malfunction in the ShiftTiming Solenoid. This solenoid is responsible for controlling the 3-2 downshift in the transmission. It is a normally-closed, onoff device that attaches to the control valve body.

The solenoid receives ignition voltage and is controlled by the Powertrain Control Module (PCM) through a ground path. When the PCM detects a continuous open, short to ground, or short to power in the circuit of the 3-2 Shift Solenoid valve assembly, it triggers the P0785 fault code. This code indicates a problem with the solenoid’s operation, which can affect the timing of the 3-2 downshift.

The timing between the release of the 3-4 clutch and the application of the 2-4 band is adjusted by the PCM based on vehicle speed and throttle position.

What are the possible causes of the automobile fault code p0785?

If you’re seeing the fault code P0785 on your automobile, it’s important to address it promptly. This code is often accompanied by the engine light being on and the transmission not shifting to the next gear.
