P252BEngine Oil Quality Sensor Circuit Range/Performance
The oil quality sensor is electrically intact, but the readings do not match the model — for example permittivity that does not change after an oil change, or shifts inconsistent with km/h driven. Often a contaminated electrode or oil that does not fit the sensor calibration.
