I put ko2s on 2 weeks ago. I was driving down the freeway and the tire pressure system quit sensing tire pressure about a week after they were put on. I've been getting "service tire pressure system" on my ECM screen. Tire shop said it should reset after driving about 20 minutes. Been doing town driving haven't taken it on the highway yet. This happen with anybody else with ko2s? If so what did you do?
It’s a problem with the system. Have it reset. In my case, a sensor had disconnected from the valve stem and was bouncing around. Reconnected it and back to normal, didn’t have a light issue either. The system is a quick relearn, so anything that doesn’t reset fast is a scanner issue typically. Take it to your tire shop and have them perform/look for a faulty sensor

Mine do the same on my geolanders. I also live in the city of Pittsburgh aka pothole city. The sensors have fallen off a few times.
