The oil in my vehicle was changed a few weeks ago now the sensor gage is showing extremly high. I wonder if the sensor is bad due to the car has been running just fine since the oil was changed.

    After changing oil its common to have higher pressure because old oil gets diluted with gas and can get very thin, then with the oil change you have thick new oil = higher pressure but if you want to change the oil pressure sending unit its about $50 at the dealer
