Prelude L4-1958cc DOHC (1989)
Throttle Position Sensor: Description and Operation
Fig. 36 Throttle Angle Sensor And Voltage Output Chart
The Throttle Angle Sensor is a linear potentiometer. It is connected to the throttle shaft. As the throttle angle changes, the throttle angle sensor
varies the voltage signal to the ECU. The ECU uses this voltage signal along with the MAP Sensor voltage signal to determine engine load. The
typical output voltage at idle is approx. 0-0.5 volts and at wide open throttle approx. 4.5 volts.
