I retract my previous statement. Oil modules were used PRIOR to the 96 model year, not since. The PCM itself contains the module starting in 96. So the only thing to look at would be the sensor in the pan or the associated wiring to it. In either case, a scantool can tell you if the circuit is bad or not.

While I suppose it'* possible you have a malfunctioning sensor, more likely you just need to top off your oil a little.

On both my '98 and '04, I have found that the oil level sensor is very sensitive, but also very accurate, consistently detecting low oil levels at about 1/8 to 1/4 quart low.

I definitely would advise not to disable or disconnect it just because you don't like seeing the light

Pretty sure just unplugging it would still continue to turn the light on....

I guess I should expand on my concerns. The level sensor in the oil pan is new. I check the oil level about once a week and it is right at the full mark. The "check oil level" signal on the DIC comes on every time I start the car. I thought I had read somewhere in the forums that there was a relay under the dash that worked with the sensor in the oil pan.

Ok, this thread is starting to get confusing, because there are two members with two different model cars having the same problem. Out of respect for the original poster, please post your issue seperately.

Smallengineguy, since you have a 1996, you do not have an oil level module...the PCM itself handles that job. I would look into the sensor wiring first, since it IS on the oil pan, and if there is a leak at the pan gasket, oil could soften those sensor wires over time. Then scan your vehicle for codes 1653 (oil lamp circuit...doubtful this will pop up since your lamp works), or 1672. Those are the only two codes I could find that are related to the issue you have.
