So I have replaced mine twice now and it is not tracking miles properly. any ideas? The drive to my house is 4.1 miles from the store. My car tracked 3.1. To my buddies house is 5 miles, my car tracked 4 miles. This is incredibly important because I drive for work and track mileage and get paid. Why would it not be tracking properly. I have replaced this twice now. and Yes everything did track properly months ago before the sensor went out.

 

have you gotten larger tires since it last worked correctly?

 

Same stock size tires

 

Go to a local auto parts store and have them scan your D using the diagnostics port. If you have a bunch of ABS module hits, it's likely the problem. Once again, I'd recommend module masters mentioned in my earlier reply.

I lied... apparently they aren't stock size but at the same time they are.
