    You'll rest easy if you reality test your sensor...
    Have your truck's engine running with a timing light strobing the marks. Bang on the engine with something heavy to make a noise to fool the sensor into thinking that it heard a pre-iginition knock. If all goes well, you'll see the timing retard briefly.
    Are we having fun, yet?
