Ok. I put front of the car up on race ramps and got under there to take a look. It looks like the sensors are pretty far back at the rear of the front tires. Not much room to work. Does the sensor use a 18mm wrench? My largest was 17mm, so I tried an adjustable wrench for now. The sensor is really tight in there! Any suggestions on how to loosen it or just get a 18mm wrench and use brute force?
