it prob. doesn't make any difference, but which way did you check? bridging the wires in the diagnostics harness under the drivers side dash, or using the screw on the ecu?

sounds like a malfunctioning light to me. or a bad ECU

It could be an intermittent code... was the light still on when you checked the code?

do these do the "at a certian milage take in for service because the check engine light is on" thing like some of the cars from the mid to late 80's did?

No, the only reason the check engine light would come on is if there was an error code.

And if the check engine light was not on when you checked it, then there was no error code to pull and that's why you got 55. The ECU thought the problem was fixed (or perhaps it was a loose wire that reconnected).

for checking on the spot you should look up which slots on that harness to bridge so that you don't need to pull up the floorboard if you don't have time. you just stick a wire in and look at the check engine light
