  • P0698 - Sensor reference voltage C-Circuit Low
    - In the case of the fault P0698 – Sensor Reference Voltage C – Circuit low, it consists of 5 V power supply from the Engine Unit to a few sensors the most likely problem is the EGR valve is internally shorting the 5 V supply from the engine control unit.
