Speed / Timing Sensor The Speed/Timing Sensor is a Hall-Effect device

that is triggered by a tooth pattern on a gear. Speed is sensed by measuring the magnetic field

change when a gear tooth passes. Engine Timing corresponds to a pattern of tooth

edges. These types of sensors are extremely accurate

because amplitude and phase are not speed dependent, unlike an inductive coil.

Throttle Position Sensor The Trottle Position Sensor is used to provide a

Trottle Signal to the E.C.M.

Sensor Output is a Constant Frequency Signal with

a Pulse Width that varies with the Trottle Position.

This Output Signal is referred to either DUTY

CYCLE or PULSE WIDTH MODULATED (P.W.M.)

Signal. This Output Signal is expressed as a percentage

between 0 an 100 %.
