Check to ensure the
pressure transducer is
properly installed and
all wires are properly
connected.

HCM
Pressure Sensor
Error A
Bad sensor.
Check if the error follows
the transducer. Disconnect
transducer cables from
the HCM (connectors 6
and 7). Reverse A and B
connections and check if
the errors follows. If the
error follows the transducer,
replace the pressure
transducer.

properly installed and
all wires are properly
connected.
P6BX
HCM
Pressure Sensor
Error B
Bad sensor.
Check if the error follows
the transducer. Disconnect
transducer cables from
the HCM (connectors 6
and 7). Reverse A and B
connections and check if
the errors follows. If the
error follows the transducer,
replace the pressure
transducer.

Check to ensure inlet
sensor is properly installed
and all wires are properly
connected.

Check if the error follows
the inlet sensor. Disconnect
inlet sensor cables from
the HCM (connectors 8
and 9). Reverse A and B
connections and check if
the errors follows. If the
