Order of inspection

  1. P0549 Exhaust Gas Temperature Sensor Circuit High (Bank 2) Medium

    The P0549 code means the exhaust gas temperature sensor signal (bank 2, sensor 1) is above its maximum value. The main effect is reduced exhaust protection. It usually points to an open circuit or an interrupted ground, and a loose connector is the most common cause.
