A non-contact type throttle position sensor is used. This sensor uses a Hall IC, which is mounted on the throttle body.
The Hall IC is surrounded by a magnetic yoke. The Hall IC converts the changes that occur in the magnetic flux into electrical signals and outputs them as throttle valve effort to the ECM.

The Hall IC contains circuits for the main and sub signals. It converts the throttle valve opening angles into electric signals with 2 differing characteristics and outputs them to the ECM.
