This diagnosis typically is Multiplexer 1, Channel 1 or 2 has a short or open circuit high.
106.1.1 Channel 1
Multiplexer 1 Channel 1, shorted high will set if the input voltage from either the DOC Temp In,
DOC Temp Out or DPF Temp Out 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.
106.1.2 Channel 2
Multiplexer 1 Channel 2, shorted high will set if the input voltage from the Turbo Compressor
Inlet 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 sensor input.
