We recently were told that our Passenger side air bag sensor was faulty. We replaced the sensor and rechecked to see if there were any codes. The Air Bag light was still on but we saw the U0121 code on our OBD2 which our search says is tied to brakes. Could this code be connected to the passenger side air bag sensor? We may have installed the old one by mistake and are trying to figure out if we need to switch them again.
