I was hoping it wouldn't be. Its not the price. Its the location. Guess that's getting swaped out next.

That could be the problem. Perhaps you should do some testing or pay someone to do some testing instead of just lobbing parts at the car.

Well I've had it since 143K and now its at 251K and never changed a sensor lol! Just oil changes brakes and ball joints. Ahaha. So I thinks its time to change up some sensors.
