It’s definitely a good one for DIY starters. However, it is important to understand that before you buy these sensors you need to know for sure that they have to be replaced. I recommend you take it to a professional to have them diagnose your vehicle and tell you the exact reason why your ABS light is on. The professional will also tell you which ABS sensor is at fault, whether it’s the front left ABS sensor, front right ABS sensor, rear left ABS sensor, or rear right ABS sensor. Another common issue is that the ABS sensor could be dirty. It could be a good idea to take the abs sensor out and clean it first before buying a replacement ABS sensor. When ABS light turns on due to a failed ABS Sensor it is common that Traction and Stability Control System will be disabled along with the anti-lock brakes. In many instances, it can cause the Check Engine Light to come on.

If you are just starting out as a DIY Car repair guy/gal it might be worth investing into your own OBD II ABS scanners. Here is a list of scanners. I recommend you don’t buy the cheapest one but invest a bit considering getting a diagnostic twice will cover the cost of owning your very own OBD2 scanner.

In addition to these instructions, there is a VIDEO below at BOTTOM of the page showing you step by step how to replace a front ABS sensor on 2010 Mazda 3.

Tools You’ll Need

                    




Instructions

1. If you don’t have a floor jack or a jack stand that is fine but as you invest time into DIY projects on your car I encourage you to invest into them instead of using the jack from your trunk. These two items will save you so much time. Prior to lifting up the car, take the lug wrench and loosen the lug nuts a little bit. Don’t unscrew them all the way, just enough to break them loose. Keep in mind your 2010-2013 Mazda 3 will have a security key on one of the lug nuts. The key can be found either in the trunk or in glove compartment box. If you don’t have one then you need to get one from the dealer.

2. Once all 5 lug nuts are loose, lift the car using a jack. Continue to loosen all the lug nuts and remove the wheel. Mazda front ABS Sensor will be located right behind the disk rotor as shown in the picture below.

4. Mazda ABS Sensor is held by one female torx screw. Unfortunately, I didn’t have a female torx socket; therefore, I used 3/16 hex socket and it worked just fine. NOTE: Do this at your own risk. I recommend you getting a female torx socket set. But in case you want to save a buck you can always do what I did.

5. Wiggle the old Mazda ABS sensor back and forth as you are pulling it with your fingers. Since you are replacing it any way you can try to use your pliers if it’s not budging. One thing that helped me was using a flat head screwdriver to pry it a bit as I continued to pull on it and wiggle it. Once the ABS sensor is removed proceed with install the new one.

6. When installing the new ABS Sensor, keep in mind that the holes should line up to avoid any issues when you will be inserting the screw. Use the female torx socket and tighten the screw.




7. Insert the wire connector back into the new ABS sensor until you hear a clicking sound.

                    

8. Put the wheel back on and tighten the lug nuts. Remove the jack stand and lower the car back to earth.

9. In some cases ABS warning light will go away on its own. If not, you will need to reset the ABS Sensor error codes. There are three things you can try to reset the ABS Sensor error codes:

  1. Use an OBD II ABS scanner, if you don’t have one buy it if you don’t want to buy it – try doing the next step. 
  2. Unplug the battery from the negative terminal first and let it sit for about 25 minutes.  After 25 minutes connect the negative terminal and start the car to check if the ABS sensor light is off on your Mazda. If that doesn’t work then refer to option #1.
  3. And the last option is to take the car to a profession to have them reset the ABS Sensor light on your 2010, 2011, or 2013 Mazda 3.

    1. Try spraying a little bit of WD-40 on it and see if that helps. Make sure that the torx screw is fully lost and out of the way as well. Also, you can try to use a small thin flat head screwdriver and attempt to pry it a bit. Hope this helps.

  3. I changed the front right wheel bearing (having to disconnect the ABS sensor in the process), and when I put it all back together the ABS sensor came on. This is a 2009 Mazda 3. Any thoughts would be greatly appreciated

    1. In the process of replacing the wheel bearing did you see something that looked like a seal. It was it a thin metal like seal that was between the inner (closer to the centre of the car) bearing and the hub housing.
      I did the same thing, to clear the way for the press to push out the old bearing. I suspect this is the bit the sensor reads to figure out wheel speed. I hope I am wrong.

  4. Thanks for a good guide. Just want to add, the needed top for the mounting screw is a female torx E6.
    I replaced the sensors at the rear too (also with E6 torx), but it was more difficult to get access there. For the rear sensor, I would recommend to crawl underneath the car to see where the sensors and screw is located, but do the work from beside the car after removing the wheels.
