Venza exhaust sensor issue

Whoa, smoke? That doesn't sound good! I had a similar problem with my old Volvo XC60, although it was a gasoline engine. The warning light and sluggish acceleration were dead giveaways. Could be the sensor, but did they check for any exhaust leaks too?

Thanks for the quick response! Exhaust leaks, huh? The mechanic only mentioned the sensor. Is it possible that a leak could trigger the sensor warning? I'm just trying to understand everything before I commit to the repair. I'm not a car expert, you know?

Definitely! A leak messes with the pressure readings, which then throws off the sensor and triggers the light. If it's just the sensor, great! But a leak could be trickier. Honestly, with smoke involved, I'd get a second opinion from a trusted workshop. Better safe than sorry!

Thanks so much for the advice! I took it to another workshop, and they confirmed it was indeed the exhaust back pressure sensor. The part plus labor came out to around 245€. Replaced it, and everything's running smoothly now. I really appreciate your help!
