Exhaust System Temperature sender - 440 Pro X
Temp sender
The temp sender that is on the 440 Pro X will read the exhaust temperature and adjust the
timing according to the temperature range.
To Test the sensor:
Unplug sensor. At room temperature the temperature sender will have a HIGH resistance
(may read Open Line (OL)) depending on your meter.
As the pipe gets hotter, the resistance keeps lowering resulting in optimum timing for a
given RPM and pipe temperature,
If the sender resistance is not responding to pipe heat the sensor may need tobere-
placed.
LOW PIPE TEMP = HIGH RESISTANCE
MEDIUM PIPE TEMP = MEDIUM RESISTANCE
HIGH PIPE TEMP = LOW RESISTANCE
