How To Clean Your ABS Wheel Sensor
发布时间：12/22/2017 9:03:17 AM
There are many things that can cause your ABS light to come on. Some are serious, so you should never just ignore the light. But there are times when the light comes on, but can be met with a simple solution. For instance, a dirty ABS wheel sensor can cause the system to trigger the ABS light during your ABS computer's self evaluation cycle. You'll be shocked when you see how much road gunk can accumulate on this very important sensor. This sensor is also used in some traction control systems, so if you've got a traction control, or anti-skid warning illuminated you might find that cleaning the ABS sensors will remedy this, as well.
Even if your ABS light hasn't made an appearance, it's a good idea to clean the sensors. A good time to do it would be during brake pad replacement when you have the wheels off anyway. At this point it's a 10-minute job rather than an hour or two.

With the sensor free, take your rag and wipe the sensor until its clean. I prefer not to use any chemicals on the sensor to avoid potential problems. If you need to, use mild soapy solution and rinse well. The ABS sensors are precision instruments in a crude environment. They're tough enough to hang off the brakes of a very fast moving vehicle, but one good knock and they could be damaged beyond repair. Keep this in mind when working with these sensors, They're tough, but a little car taken while you service the antilock braking system along the way can save you from another costly repair added to the brake service.
To finish up the job, reinstall the sensor in the same manner it was removed, taking care to install the sensors in exactly the same manner as they were removed. Don't skip the step of reattaching the line or wiring to those mounting points. They may seem like they don't matter, but it can get very expensive if you make a bad decision.
*Don't be discouraged if your ABS light doesn't turn off right away. It may take up to a few days for the system to reanalyze itself and reset fully.
