Supply Voltage

Systems Operation Section

Supply Voltage Supply voltage is a constant

voltage that is supplied to a component in order

to provide electrical power for operation. Supply

voltage may be generated by the ECM. Supply

voltage may also be the battery voltage of the

vehicle that is supplied by the vehicle wiring.

"T" Harness This harness is a test harness that

is designed to permit normal circuit operation and

the measurement of the voltage simultaneously.

Typically, the harness is inserted between the two

ends of a connector.

Throttle Position The ECM interprets a signal that

is sent from the throttle position sensor in order to

determine the throttle position. The throttle position

may be used as part of a power take-off control.

Total Tattletale The total tattletale is the total

number of changes to all system parameters.

Transducer A transducer is a device that converts

a mechanical signal to an electrical signal.

Vehicle Speed Sensor A vehicle speed sensor is

an electromagnetic pickup that measures vehicle

speed from the rotation of gear teeth in the drive

train of the vehicle.
