THROTTLE POSITION SENSOR
With the switch set to "ON" at a variable voltage
between 0.7V and > 4V between pins 23 - 3 on
engine-side wiring.
Ground insulation of pins 29 - 32 - 3 on engine-side
wiring
Pins 1(A) - 3(C): Throttle valve closed: approximately 2.5 kOhm; throttle valve open: approximately 1.5
kOhm
Pins 1(A) - 2(B): approximately 1.1 kOhm
Check the continuity between pin 3 of the sensor connector and pin 3 of the engine connector control
unit.
Check the continuity between pin 2 of the sensor connector and pin 32 of the engine connector control
unit.
Check the continuity between pin 1 of the sensor connector and pin 29 of the engine connector control
unit.
Check that the three lines are ground insulated.
Zeroing the throttle
Resetting the throttle valve position signal (TPS reset)
The MIU control unit is supplied with a throttle valve position sensor that is pre-calibrated.
Pre-calibration entails regulating the minimum opening of the throttle valve to obtain a certain flow of
air under pre-set reference conditions.
Pre-calibration ensures optimal air flow to control idling.
This regulation must not be tampered with in any way whatsoever.
The injection system will complete the management of the idling through the Stepper motor and the
variation of the ignition advance.
The throttle body after the pre-calibration has an opened valve with an angle that can vary depending
on the tolerances of the machining of the pipe and the valve itself.
The valve position sensor can also assume various fitting positions. For these reasons the mV of the
sensor with the valve at idle can vary from one throttle body to another.
To obtain the optimum fuel mixture, especially at small openings of the throttle valve, it is essential to
match the throttle body with the control unit following the procedure known as TPS resetting.
With this operation we inform the control unit, as the starting point, of the mV value corresponding to
the pre-calibrated position.
To reset, proceed as follows.
