TP sensor

• Installed on the side of throttle body.
• A potentiometer type has been adopted.
• Detects the fluctuation in voltage (variable resistance) of the throttle valve opening angle and outputs it to the PCM. The voltage input to the PCM increases in proportion to the increase in throttle valve opening angle.
• Installed to the valve shaft so that it is linked to the opening and closing of the throttle valve.
