I've got a 1995 GSR Sedan, the ABS light comes on whenever I take of the gas cap to fill the tank up. After I fill the tank and put the cap back on, the ABS light stays on till I turn off the motor. when I start the car back up later on, the light does not come back on till the next fill up. I purchased a new gas cap and that didn't solve the issue. I took it my mechanic and he pulled a Code 1-8, mechanic said he couldn't figure it the code. If anyone on the forum know what the code means, please chime in and clue me in.

Thanks in advance Honda-tech peeps
