That comes up on my DIC when I start the car, but usually goes off within 20 seconds or so. YES I CHECKED THE OIL! Is there a specific sensor for oil level, and where is it? Thanks!

yes, it is on the front of the oil pan.

Is it called the "oil level sensor" when I call NAPA for it?

Yes.

But, I'm not certain your current one is a problem. It used to stay on for about 20 seconds in my 99 SE when the car was first started.

Has it noticably stayed on longer than it used to?

NO it has not. I've only had the car 2 weeks, and it doesn't come on every time you start it either. I'd say 50%.

This may not be the case on your '98, but on my '92 and '93, there'* also an electronic oil level module on the passenger side behind the dash. When the oil light started turning on in my '93 SSEi, I replaced the oil level sensor on the pan, but the oil light still came on so I disconnected the connector to the oil level module. The oil light never turns on anymore. Someday I'll find a replacement oil level module and replace it so that system will work again.

My 93 SSEi has the same problem currently with the "check oil level" indicator on the DIC. To get at the sensor thats on the passenger side do I need to remove the dash or can I pull a Gumby and get at it from below???

The sensor on the passenger side is for PRESSURE. Not level.

The sensor you need is in the front face of the oil pan.

To add, the oil level module is found in the 96-up models, and ties into the PCM believe it or not. I forget the code for it, but if there is something wrong with the module, it will let you know via codes (I think it will NOT illuminate the check engine lamp, just store the code).

LondonOntMan, If you haven't already done so, try replacing the oil level sensor in the oil pan first. If that doesn't fix the problem, you can disconnect or replace the oil level module. The oil level module on a '93 SSEi can be accessed by removing the lower dash cover on the passenger side. The module is black plastic, and is mounted near the firewall, just below and left of the area where the ECM and all other modules are located. It'* a bit difficult to get to. It'* mounted on a plastic or metal rail (I don't remember what it'* made of). To remove the module, push or pull on the clip that holds it in place, and then pull the module down.
