Product overview

A heated 4-wire downstream oxygen (O2) sensor for many Ford and Lincoln models, including the Ford GT. It sits after the catalytic converter and reports how well the converter is working. A failing downstream sensor often triggers a check engine light and catalyst efficiency codes and can cause a failed emissions test.
