On my way to work today, I looked to check my speed, and noticed my check engine light was on. I pulled over, and before I turned off my engine, the CEL turned off. I checked under the hood and I found I was a little low on oil. I put the rest of the quart I had in, and drove the rest of the way to work (.5 miles). The light never came back on. Could this have been caused by being low on oil, or should I check if I threw a code?

Its a 93 rodeo 3.2 Auto

-Thanks

In my little world -- if the light comes on, I'll look for a code... Always. (it's cheap insurance against something kinda silly happening when it'd be less convenient)

Yeah, thats what I was thinking, but when I was searching around on this forum, alot of people metnioned it wont show a code unless the light its on.
Can someone post the instructions to read the code?

A 93 Rodeo has a 3.2 SOHC, I have the DOHC, but hopefully checking the codes is the same.

The ALDL is located behind and slightly lower than the stereo, toward the driver's side (near where your right calf sits as you're driving).
Mine is bundled together with two other connector thingies; there's a white one with 3 wires, a green one with 3 wires, and a smaller white one with only one wire. You want the white, 3 wire one.
With the key off, put a jumper wire on the two outboard terminals. Turn the key to "on" and the CEL flashes code 12 3X to tell you it's in diagnostic mode, then it'll flash each code 3X.

My experience has been that the code 32 (EGR) will set give me a CEL that goes off at idle and comes back on at ~1700 rpm. I clean out the EGR valve, vacuum lines and such, and it's good for another 8K miles or so. I thought maybe I had a weak ignition system or something, but my plugs are never fouled. <img src="/forums/images/graemlins/confused.gif" alt="" />
