the 8v oil temp sensor is on the oil filter housing, its the small one with a white coloar, the wire to it is green/black. it wil read --- till the oil gets over 50 degrees tho

as for outside temp will be skipped over if the sensor has come unplugged, its behind the wing on the passenger side, clipped into a hole at bumper level. they often fall out o the hole then eventually the sensor falls off the wiring loom
