ACDelco Oxygen Sensor — Upstream Severe Duty
ACDelco · SKU TVX-DEMO-0171 · MPN ACD0171OX
An oxygen sensor measures exhaust gas oxygen so the engine computer can correct the fuel mixture. Upstream and downstream sensors are not interchangeable, and wire count and connector differ between vehicles. A failing sensor commonly causes poor fuel economy and an emissions warning.
