Temperature Sensors.
a.
Air inlet temperature sensor and coolant temperature sensor are passive sensors. Each sensor provides a tempera-
ture input to ECM. ECM controls fuel delivery and injection timing.
b.
Sensor operating range is -40 to 302F (-40 to 150C).
c.
Sensors are also used for engine monitoring.

Voltage Load Protection Module. Voltage load pro-
tection module monitors system voltage. Voltage load
protection module will shut down fuel injection pump
if there is a high system voltage.
