Venza exhaust sensor issue

I've got a 2020 Toyota Venza hybrid with only 20070 km on it. Recently, a warning light popped up and I've noticed some smoke when accelerating. A local mechanic said it's likely an exhaust back pressure sensor malfunction. Has anyone else experienced this? Is it a common issue, or am I just unlucky?

A 2020 Toyota Venza hybrid with 20,070 km exhibited a warning light and smoke during acceleration, suggesting a potential exhaust back pressure sensor malfunction. A local mechanic identified the sensor as the likely issue, but another user suggested checking for exhaust leaks, as they can affect pressure readings and trigger warnings. After seeking a second opinion, it was confirmed to be the sensor, which was replaced, resolving the problem.

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!
