Corvette exhaust temperature sensor issue

I'm experiencing an issue with my 2023 Chevrolet Corvette, gasoline engine. The car has 206048 km on the clock. The check engine light is on, engine power is reduced, and fuel consumption has increased. I suspect a faulty exhaust temperature sensor, possibly due to a leak in the exhaust system. Has anyone else encountered similar issues?

A 2023 Chevrolet Corvette owner reported issues with the check engine light, reduced engine power, and increased fuel consumption, suspecting a faulty exhaust temperature sensor due to a potential exhaust leak. The problem was confirmed by another individual who experienced similar symptoms and suggested checking for exhaust leaks. The issue was resolved by identifying a hairline crack near the sensor, which was fixed by a mechanic, resolving the problem.

I had something similar happen on my Corvette. Check engine light, felt like I was towing a boat, and my gas mileage tanked. What codes are you pulling?

Thanks for the reply. I'm pulling a P0544 code - Exhaust Gas Temperature Sensor Circuit Malfunction (Bank 1). Did you have the same code, or something similar? Was it definitely the sensor, or something else causing it?

Yeah, that sounds familiar. I had the same code. While it could be the sensor itself, a small exhaust leak near the sensor can also trigger it. Considering the symptoms, I’d advise getting it checked by a workshop to pinpoint the issue.

Thanks, I appreciate the confirmation. Took it to a mechanic who smoked the exhaust lines. Turns out there was a hairline crack near the sensor. Sensor and welding cost me 265€. Issue resolved.
