That's what fixed my light. I had a replacement sensor put in but Discount's TPMS software cant re-program the sensor, they promised future software upgrades will take care of it. After reading about the psi and temp problems it was time for a well placed piece of tape, no more issues. It would be different if it read back tire pressure but just on/off is not worth the hassle. I love my conti DWS's also.
