throttle from opening easily or fully closing.
Engine Coolant Temperature Sensor
1
.
Description and Working Principle
This sensor is used in water cooled engines. It provides a resistance that varies as a function of
temperature within prescribed tolerance limits. The sensor has a negative temperature
coefficient of resistance. This is a non-serviceable part.

Installation Requirements
•
Dynamic Torque Requirement: The sensor shall be hand into the application and then
driven by a driver with a maximum no load speed of 400 rpm or installed to the desired
torque by a hand torque wrench (5/8” hex). The recommended installation torque is:
Minimum: 20 N·m
Maximum: 25 N·m
•
Static Torque Requirement: The torque required to remove the sensor from the mating hole
shall be within 200% of the installation torque mentioned above.

Sample Cleaning
•
When necessary the samples may be cleaned in isopropyl alcohol for one minute with
mating connectors in place and then air-dried
Intake Air Pressure and Temperature Sensor
1
.
Description and Working Principle
This sensor has two functions. The first is the intake manifold air temperature, it provides a
resistance that varies as a function of temperature within prescribed tolerance limits. The
second is the intake manifold air pressure; it provides a voltage varies as the intake air
pressure.
