HI, I have a problem w/ my integra ebrake lite. When i start to run my car for the 1st and 2nd shift, the ebrake lite will turn on if i go over 2000rpm, on the 3rd shift, the lite will turn off by itself...i checked the master cylinder, brake fluide, brake pads and everything looks fine to me. Will that be just a problem of the O2 sensor??
