Road Speed Transducer

Road speed transducer is fitted between upper and lower speedometer cables. Road speed transducer is mounted on a bracket located on left hand chassis side member adjacent to rear engine mounting. Road speed transducer provides road speed data to Engine Control Module (ECM). ECM detects vehicle movement from road speed input and ensures idle speed control mode is disengaged. Should road speed transducer fail in service ECM idle speed control would become erratic.
