Tire Pressure Light

This started over a week ago at the track. On one of my last runs the tire pressure light came on. I figured it had to do with the heat in the tires and dismissed it. I tried to reset it a couple times on the way home from the track with no luck. Got home and checked the pressure and took out some air out. I tried to reset again with no luck. I read the manual and it told me that the way the light was blinking then solid was an indicator that one of the sensors had gone bad or I had an issue with one of the tires. I did an inspection of the tires again and couldn't find anything. I did a good water spray around the tires thinking that maybe some brake dust or rubber had gotten in the way of the sensor. Again, no luck and the light would blink then turn solid. I don't want to take it to the shop for this and was wonder if any of you had any other suggestions.
 
Also - I am running Michelin PSS 255/40/18 @ 32 psi cold & 225/45/18 @ 32 psi cold
 
You might take off the front wheels and locate the actual ABS sensor location. Confirm the gap to the sensor ring isn't obstructed. The setup at the rear makes it unlikely to get obstructions, but you could check any way. Also check that all wiring connections are secure. The only way to tell which sensor has gone bad is with DIS/INPA software. Besides dealers, some independents have it, and if you're good with computers, it can be obtained off fleabay, but getting it working is the far opposite of plug and play.
 
Update on this thread

I took my car to an independent shop, they said the diagnostic tool told them both rear TPM in the tires were showing faults. I had them replaced and still getting the TPM light on the dash.
