Auris exhaust leak causes sensor issues

Hi, I've got a 2010 Toyota Auris with a gasoline engine and I'm having some trouble. The check engine light is on, the engine feels less powerful than usual, and I'm burning through fuel like crazy. I've heard it might be the exhaust temperature sensor. Anyone else had this?

Hey! I had something similar with my Auris. Check your exhaust system for leaks! A small leak can mess with the sensor readings and cause those exact symptoms.

Interesting. Where exactly should I be looking for the leak? Is there a common spot where they tend to appear?

For me it was near the catalytic converter. Honestly, unless you're experienced with exhaust systems, it's probably best to get a mechanic to take a look. It could save you a lot of time and potential headaches.

Thanks for the advice! I took it to a workshop, and you were spot on – a small crack in the exhaust caused the faulty sensor readings! New sensor and exhaust repair cost me 265€. Runs like new now!
