About P0795

P0795 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0795 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0795 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The fault code P0795 is set when the transmission control module (TCM) or the engine control module (ECM) in vehicles with integrated control systems detects an open circuit in the pressure control solenoid 'C'. This solenoid is responsible for regulating the hydraulic pressure used in the operation of the transmission, particularly for controlling gear shifts. An open circuit means there is a break in the electrical path required for the solenoid’s operation, which can lead to a lack of control over transmission pressure, potentially causing issues such as erratic shifting, slipping gears, ...
