sensor is faulty, the
wiring to the sensor is
broken, or the wiring or
connector is
disconnected.
Using the wiring schematic for the machine,
locate the Oil Injection temperature sensor
connection to the controller. Check for
disconnected wires, plugs, or loose connections.
Inspect the cable for damage between the
controller and the sensor. Remove the cable
connector from the sensor and use a multi-meter
to check the resistance of the sensor and ensure
that it is not open (very high resistance). It is
possible that the sensor may read within range at
room temperature but still be faulty once exposed
to an elevated temperature or vibration. Replace
or repair the wiring or sensor depending on the
results of the findings.

Using the wiring schematic for the machine,
locate the Enclosure temperature sensor
connection to the controller. Check for any
