P0198

Engine Oil Temperature Sensor High

DTC P0198, sometimes indicated as P019800 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing engine oil temperature sensor high.

A P0198 code means that the engine oil temperature sensor is reading too high. This can be caused by a number of things, including a bad sensor, a problem with the wiring or connector, or a fault in the engine oil control system.
If you have a P0198 code, the first thing to do is to check the engine oil level and make sure that it is correct. If the oil level is correct and the code persists, then you will need to have the sensor checked to see if it is bad. If the sensor is bad, it will need to be replaced. If the wiring or connector is bad, it will need to be repaired or replaced. If there is a fault in the engine oil control system, it will need to be diagnosed and repaired.
