Fiat Argo knock sensor issue

My 2018 Fiat Argo with a gasoline engine has an illuminated malfunction indicator lamp, increased fuel consumption, and uneven idling. I suspect a defective knock sensor, maybe a faulty cable or plug connection. Has anyone else had this?

I own a Fiat Argo too, though not sure of the year. Your description rings a bell. I had similar symptoms - check engine light, reduced fuel efficiency, and rough idling. The warning light was most concerning. It ended up being the knock sensor for me. Did you check the error codes?

I retrieved the error code, which pointed to the knock sensor. Based on your experience, do you think a defective cable or plug connection is the likely cause?

A defective connection is possible, but it's hard to say without looking at it. Given the symptoms and error code, a qualified technician should examine it. They can run tests to find the problem and suggest what to do. It's safer to let a professional inspect it.

I'll schedule an appointment with a mechanic for a diagnosis. The estimated repair cost, including parts and labor, is about 95€. Thanks for the help.
