Peugeot 106 check engine light and power loss

I've got a 2000 Peugeot 106, gasoline engine, and recently the check engine light keeps popping on. I've noticed the engine feels less powerful than usual, and the fuel consumption seems to be higher. The car has only 24284 km. I've checked the basics like fluid levels, but I'm stumped. Could it be a faulty exhaust temperature sensor?

Sounds familiar! I had similar symptoms on my old Volvo V70 – check engine light, sluggish performance, and drinking fuel like crazy. Turned out to be a leak in the exhaust system messing with the readings. Have you had a look for any hissing sounds or soot around the exhaust?

Interesting! I haven't specifically looked for leaks, but I'll definitely check that out. Where exactly on the exhaust system should I be looking? Any specific components that are more prone to leaking, like around the exhaust sensor?

On my Volvo, it was a cracked flex pipe right before the catalytic converter. The garage found it pretty quickly with a smoke test. Honestly, with exhaust issues, unless you're really comfortable working on cars, it's often best to let a pro take a look. They'll have the tools and know-how to pinpoint the exact problem.

Thanks a lot for the advice! I took it to a workshop, and you were right – a small leak in the exhaust was causing the exhaust temperature sensor to give incorrect readings. They replaced the sensor and fixed the leak. Cost me 265€, but now it runs like a charm again!
