Throttle Position Sensor (TPS)

TPS is mounted on side of rear throttle body and is connected to throttle shaft. A throttle rod connects both front and rear throttle body units to ensure throttle valve of each unit is positioned the same. This sensor converts throttle angle to an electrical signal for use by ECM to determine engine fuel requirements.

NOTE: The throttle rod end bearing is permanently attached to throttle lever stud of rear unit. Throttle rod must not be removed from rear unit. If throttle rod bearing needs replacement, rear throttle body unit must be replaced.
