4. THROTTLE POSITION SENSOR (TPS)
A Throttle Position Sensor (TPS) is used to monitor the
position of the throttle operation and is located on the
butterfly spindle so that it can directly monitor the
position of the throttle. The sensor is a potentiometer
type and therefore provides a variable resistance
depending upon the position of the butterfly valve
and hence throttle position can be sensed by the ECU.
The sensor signal is used by the ECU as an input to its
control system. The ignition timing and fuel injection
timing (and potentially other parameters) are altered
depending upon the position of the throttle, and also
depending on the rate of change of the position.
The ECU uses the throttle valve position to know:
Engine mode: Idle, Part Throttle, Wide-Open
Throttle (WOT)
Air-fuel ratio correction
Acceleration / Deceleration correction
5. MANIFOLD ABSOLUTE PRESSURE (MAP)
SENSOR
The Manifold Absolute Pressure sensor provides
instantaneous manifold pressure information to the
ECU. This is necessary to calculate air density to
determine the required fuel metering for optimum
combustion and influence the advance or retard of
ignition timing.
It is mounted under the fuel tank on frame as shown
in photo.
