P250A — Engine Oil Level Sensor

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Land Rover

About P250A

P250A is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Land Rover vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P250A 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 P250A 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

DTC P250A is set by the Engine Control Module (ECM) when an electrical or plausibility fault is detected in the engine oil level sensor circuit. The oil level sensor, commonly a thermal or capacitive type mounted in the sump, reports oil level and on some applications oil temperature or condition to the ECM so it can warn the driver and protect the engine. The fault is logged when the oil level signal is outside the expected voltage range, remains fixed, or does not correlate with operating conditions such as engine run time, oil temperature, or recent oil changes. When the code is set, the dr...
