Throttle position sensors are used to inform the ECU of how much load is being applied. The throttle position sensor informs the ECU rate of throttle change to calculate acceleration fuel & when the throttle is closed, this information can be used to enable the ECU to do idle control.

They are commonly used on single or multi-throttle body applications. They are also used on turbo engines in some applications.

The throttle position sensor shown below is the most common type we use on our throttle body kits. Most OE engines have throttle position sensors* as standard, you will be able to configure the MBE to suit.

*Some engines have throttle switches, they look identical to throttle position sensors, please check to ensure which type you have.
