What does a bad oil pressure sensor look like?
The Oil Pressure Light is on If the Low Oil Light comes on, but you check the oil in the engine and it’s at a good level, then a faulty oil pressure sensor may be to blame. When this sensor goes bad, it will start to give inaccurate readings. After the readings fall out of specification, a warning light is set.
