About the only way to do it would be to hook it up to a TechII (dealers have them) and it can tell if the sensor is good or not (unless it is still reading correctly)

Still wouldnt be a bad idea to hook it up to a techII, it can do a test on the entire car to see if everything is running right.

yes that is true, but using a TechII makes things a whole heck of a lot easier!!
