Ford Windstar exhaust back pressure sensor issue

Help! My 2003 Ford Windstar (gasoline engine) is acting up. I'm getting a warning light on the speedometer and seeing smoke when I accelerate. Suspect it's the exhaust back pressure sensor acting up. Anyone else seen this?

That sounds like it could definitely be the exhaust back pressure sensor. Is your engine performance suffering? Like, is it sluggish or idling rough? A bad sensor can really mess with your emission control system, too.

Yeah, the engine feels a bit sluggish. How crucial is it to replace this sensor immediately? I'm trying to gauge the urgency.

Well, if it's genuinely the exhaust back pressure sensor, it could lead to more serious issues down the road. A defective sensor can cause your engine to run inefficiently, and prolonged exposure to that can damage other components. My advice is to take it to a workshop and let them confirm it.

Thanks! Workshop confirmed it was the exhaust back pressure sensor. Got it replaced for 245€. Runs like a champ now!
