HOW TO: Replace a wheel speed sensor on a Fiat 500

[Michael T]

My particular car is a 2013 Abarth that is a manual transmission. This is my first time writing a how-to, and as always working on your car is AT YOUR OWN RISK and my how-to is merely a guide to help others.

Put car on jack stand


Locate sensor behind the rotor, it is on the actual hub. I used a 3/16 to get it off. Once the bolt is out, you just pull the sensor straight out.


Since I have coilovers, I don't have ALL the same mounting points, but after taking off the sensor, I removed the wiring from the clip in points on the inner fender. They wiggle right out.


Next I took the wiring out of the plastic clamp on the innder fender, and took off the nut from the fender trim. There is also a screw on that panel by the nut, I removed it before snapping the picture.


I quickly realized there were more bracket behind he fender well so I decided to take out more screws so I did not break anything.


Don't miss this guy he is on the bottom of the bumper.


Now you can pull back the fender liner JUST enough to get to work without breaking anything. Here you can see three more clips including the one holding on the connector for the sensor.


Here is the male end of the connector, just push on the top of the clip to free the resistance and pull back. Super easy.


Here is the female end. You can see how it slides onto the bracket that is on the car. It just slid right off for me.


Reverse the order and you are done!

Here is the actual part number




The real kicker is I found the part for 11 dollars shipped on Ebay. The dealership wanted a hundred and fifty bucks to do this simple job. Not counting jacking up and getting the wheels off, the actual job took me no more than 20 minutes. Count everything and it is around 30 minutes.

Hope this helps!

Thanks for the great write up and all the photos! I love seeing stuff like this, and especially hearing how much $$ you saved! That's one of the great things about the forum, sharing info like this!

We don't have a contest for "Thread of the Month", but if we did you'd win easy!

Thanks guys, I am hoping this can help lots of people in the future. When you Google this topic now, nothing comes up specifically for our car.
