If it has a female space connector buried in a rubber boot, that improves the odds. If there's a double-male adapter plugged into it it's a sure thing. If it's not shorted to ground, you should see ~0.4 volts on it with ignition on, sensor unplugged. If it *is* shorted to ground then the engine will run rotten. Usual place for a short is where the coax braid ends, just before the female connector. YOurs, david
