As the title says. My oil pressure is great (about 70), plenty new oil (recently changed) Could this be a switch problem or is there something else? It is the red light on the dash that stays on.I am scared to run it. Motor has 25,000 miles on a rebuild. If it is a swith, how can I test it. I believe it is in the oil pan. Thanks.

 

The oil light on a 1st-gen -7 is not triggered by oil PRESSURE, but by oil LEVEL.

If you are sure you are properly filled (within the hash marks on the dipstick, preferably at or near the top when warm) then you most likely are fine, and just have a sensor problem; either a bad oil level sensor (left side of the oil pan) or an open in the wiring for it.

 

Fb use a short to ground system for the oil level sensor. When the float on the sensor in the oil pan falls, it shorts the circuit to ground and illuminates the light. If you look on the drivers side of the motor, there should be a single wire sensor with three bolts holding it in. Unplug the one pin square style connector and see if the light goes out. If it does, you have a faulty sensor. Next time you change your oil, unbolt it and give it a good cleaning. They are a simple sensor. Of course, this is all assuming that there actually is oil in your sump.

 

Thanks guy's. I knew it was for oil level but was unsure if it was not sensing other problems. I changed my oil about a 10 days ago and checked the oil on the dipstick and it was fine. I will Unplug the one pin square style connector and see if the light goes out as instructed and if it is bad is there a cleaning or anything I can do to repair or just buy a new one? Thanks again. This place rocks.

 

Interesting in re: FB's using a float sensor; SA's use a conductivity sensor, and loss of ground through the oil itself lights the light - - similar to the water level sensor on the rad.

 

If the sensor is bad take it out next oil change. If you examine how it works you should be able to figure out what's not working on it. It's a very simple device.
