About P0941

P0941 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 P0941 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 P0941 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 P0941 fault code is set when the control module detects intermittent signals in the hydraulic oil temperature sensor circuit. This circuit is crucial for monitoring the temperature of the hydraulic oil in systems like automatic transmissions or power steering units. An intermittent fault indicates irregular, sporadic, or inconsistent signals from the hydraulic oil temperature sensor to the control module. Such intermittent behaviour can be due to loose or corroded connections, intermittent shorts in the wiring, or issues within the sensor itself. These irregularities can lead to unpredicta...
