 Okay. It's one of three things, right? It's either the sensor, the wiring, a connection, or the PCM. I can't see it being the PCM. The failure rate is probably 1%. Okay. Sensors are more likely, and then we've got to get into wiring and connections. The fact that it was sold to you with the light on, in the back of my mind, I'm thinking somebody was picking at this for a while, and they couldn't resolve it.
