This diagnosis is typically Multiplexer 2 Channel 1 or 2 short or open circuit high.
107.1.1 Channel 1
Multiplexer 2 Channel 1, shorted high will set if the input voltage from either the Engine Coolant
Temperature Sensor, EGR Temperature Sensor or Turbo Compressor Outlet Temperature Sensor
exceeds 2.97 volts, which may be caused by a short circuit, or more likely an open circuit. This is
an information code only indicating a default value will be used for the other sensor inputs.
107.1.2 Channel 2
Multiplexer 2 Channel 2, shorted high will set if the input voltage from either the Engine Oil
Temperature Sensor or Engine Fuel Temperature Sensor exceeds 2.97 volts, which may be caused
by a short circuit, or more likely an open circuit. This is an information code only indicating a
default value will be used for the other sensor inputs.
