P250DEngine Oil Level Sensor Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P250D is stored when the oil level sensor line rises above its valid range. The usual explanation is contact with a positive conductor; with pull-up inputs an interrupted line or missing sensor ground can also drive the signal high. Deutz gives the clearest definition: its EMR controller files P250D-00 as the level sensor shorted to battery. Ford lists P250D in the 2014 BOSS 302S engine code table. No passenger-car maker has published thresholds or a service bulletin for this code. A reading stuck high can mimic a full sump, so a real oil loss might go unreported until P250F logic or the oil pressure switch reacts. The low counterpart is P250C, the erratic one P250E, the generic circuit code P250A.
