Lower oil pressure.

The oem type oil pressure gauge can go bad over time and read a lesser oil pressure to the point where the check engine light will go off. Usually another sensor will correct it. I have gotten bad replacement sensors right out of the box. A quality mechanical like an Auto Meter is nice to have as a backup. You can purchase them with stainless steel hoses.
