About P0907

P0907 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 P0907 is stored, the module has detected a signal or supply voltage higher than the expected operating range.

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 P0907 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 P0907 fault code is set when the transmission control module (TCM) detects a high voltage condition in the gate select position circuit. This circuit is tasked with monitoring the lateral (left/right) position of the gear selector in vehicles with manual or semi-automatic transmissions. A high voltage condition in this circuit suggests an electrical issue where the voltage level exceeds the normal operating range. This can lead to inaccurate or inconsistent readings of the gear selector's position, potentially affecting the vehicle's gear selection process and overall transmission performa...
