I've had a recurring problem on my '99, ever since I bought the car, where every other race weekend (or so), the car will throw code P0705 ("Neutral Switch Circuit Malfunction"). It happens so frequently that I've gotten to almost ignoring the CEL.
Some years back I disconnected one (or both?) sensors and the codes disappeared - I never noticed any impact on engine performance.
Last time we had the engine out of the car, they got reconnected and I'm throwing the codes again. I'd like to disconnect it again, but I can't remember which sensor wires I disconnected/snipped last time. The one on the top of the transmission housing (the one that is almost impossible to get a wrench on from under the car), or the one on the side of the housing? (or both?)
Any words of advice or warning about doing this?
