Crown Victoria Exhaust Sensor Issue
Summary of the thread
A 2008 Ford Crown Victoria owner experienced a check engine light, reduced power, and increased fuel consumption, suspecting a faulty exhaust temperature sensor. A possible cause identified was a leak in the exhaust system, which can disrupt sensor readings and lead to these issues. The recommended solution was to have a professional inspection, which confirmed a small leak affecting the sensor, and the issue was resolved after repair.

Thanks! I'll check for leaks, but could a small leak really cause all those symptoms? Reduced power and higher fuel consumption seem like big effects for just a little hole.

Yep, even a small leak can throw off the whole emission control system, triggering the sensor and causing those problems. Honestly, I'd recommend taking it to a workshop. They'll be able to properly diagnose and fix any exhaust component issues.

Okay, appreciate the advice! I took it to a local mechanic, and you were right, there was a small leak causing the sensor to read incorrectly. Repair cost was 265€, but at least it's sorted now. Thanks again!

Sounds familiar. I've got a Crown Vic too, and I had similar issues. It could be a leak in your exhaust system, messing with the sensor readings. Have you checked for any obvious damage?
