Oil light on
#2
Sensor could be bad. Happened to me, I changed out my sensor and the problem went away for awhile. It started happening again so I replaced sensor again, this time with a GM sensor. Light went out for awhile, then started coming back on. I finally just unplugged the sensor and bypassed it. I just make sure to check my oil level every now and then to make sure its good. No more annoying light.
