Used on our CFI system and many other fuel injection systems
It uses a common 7mm diameter "D" shape drive and is mounted via the 4mm holes.
Sensor has a standard 3 pin junior timer socket.
Resistance = 2.5K ohm.
Pin 1 = +ve supply (usually 5V from ECU)
Pin 2 = -ve (ground)
Pin 3 = TPS Signal (to ECU)
Distance between mounting holes (center to center) = 55mm
Spindle shaft is offset by 5mm
Holes and spindle shaft are inline
Spindle drive should be 7mm OD with flat side
