Can the oil sensor cause problems with the computer. I have a 2000 deville
A bad oil pressure sensor would cause false oil pressure readings and maybe a oil light but won't make the car run bad. Actual low oil pressure could seize your engine.
Cars not running bad. When I had the oil changed I reset the oil sensor. Can it cause computer problems.
Are you talking about the maintenance reminder? No problem.
Would low oil in a 2003 Cadillac DeVille cause car to over heat ???
Yes it could but don't worry as it won't run long with oil that low.
