My Toyota mechanic said that the wiring coming out of the triple-pressure switch had corroded and grounded together, causing a short in the ECU... supposedly I've now lost a ground that goes to the relay or something like that... now that everything's been repaired (except for the ECU), I'm gonna try and get the ECU replaced under the warranty (thanks Brent)... any other suggestions? I don't know what to do, but I don't see why I should be out of pocket $700 because of some crappy Nissan wiring...
