XC70 Smoke on Acceleration

I'm having trouble with my 2001 Volvo XC70, gasoline engine, about 223k kilometers on it. Recently, the warning light popped up, and I've noticed smoke when I accelerate. I'm pretty sure it's the exhaust back pressure sensor. Anyone else run into this?

I have an XC70 too, and I had a similar problem. Warning light and everything. Is your engine performance also down?

Yeah, the engine definitely feels sluggish. Did you end up replacing the sensor? And did that fix the smoke?

Yes, replacing the sensor fixed the issue. However, I had it done at a workshop.

Thanks for confirming! I bit the bullet and took it to the shop. They replaced the exhaust back pressure sensor for 245€, and it solved everything! No more smoke, and the warning light is gone. Really appreciate the help!
