After having my oil changed last week my oil gauge does not work properly. It nows will register above 80 when the engine is running and when the engine is turned off it stops at 40 and does not return to zero. Could they have damaged a sensor or is the gauge going out and needs to be replaced.

Check the oil pressure with a mechanical gauge if normal replace the oil pressure switch/sensor if it continous -could be the guage is out of calibration
