Ecosport NOx Sensor Issue

Hey, I'm having a weird issue with my 2011 Ford Ecosport with the gasoline engine. Odometer's at 206523 km. The check engine light is on, and it's throwing a NOx sensor error. Plus, I've got an exhaust leak. Could it be a bad cable or plug to the sensor, or am I missing something?

NOx sensor on an Ecosport, eh? Sounds familiar. I had similar issues a while back; check engine light, the works. Is it running rough at all? Could be a bad sensor, but check the wiring like you said. They don't last forever.

Thanks for the quick reply. The engine seems fine, no loss of power or MPG. When you had this, was it just wiring, or did you have to replace the sensor? How did you figure it out?

No rough running is good. For me, it was the sensor. I'd get the shop to check the sensor readings. If they're way off, you know. You can swap the sensor yourself; they quoted me 95€ for the whole job. I'd get it done soon since it can mess with the catalytic converter.

I appreciate the advice. I'm booking an appointment with my mechanic to check the NOx sensor and wiring. I'll let you know what happens. Thanks again!
