About P0937

P0937 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 P0937 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

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 P0937 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 P0937 fault code is set when the control module detects an issue within the hydraulic oil temperature sensor circuit. This circuit is responsible for monitoring the temperature of the hydraulic oil in systems such as the transmission or power steering. The fault typically indicates a problem with the signal from the hydraulic oil temperature sensor, which could be due to sensor malfunction, wiring issues, or problems with the control module itself. Accurate temperature readings are crucial for the optimal operation of hydraulic systems, as temperature can significantly affect the viscosity...
