Went to the dealership where I bought my Hyundai Tiburon. My ABS light stays on. They brought it to the back and told me it was my speed sensor on my right rear tire or front tire and it needed to be replaced. Does this sound right? I figured it would be an o2 sensor. Also, they are wanting to charge me $300 to fix it. Are they fairly easy to fix if I did it myself?
ABS stands for Antilock Braking System. Why would you think an Oxygen Sensor, installed the exhaust, has anything to do with the brakes? The ABS sensor is integral to the Wheel bearing assembly on most vehicles, that and an hour labor sounds like $300 is reasonable. However, an independent mechanic shop can usually do the exact same quality job for less. Their labor rate is lower, and they won't need to install a gold plated part, shipped to the from Japan. You can not do it yourself, since you don't even know which wheel speed sensor is defective, nor where the O2 sensors are. Edit: The parts jockeys at Auto Zone are employed to sell car parts. They are NOT trained to diagnose the ACTUAL problem. Please take the vehicle to a trained mechanic for a proper diagnosis and repair. Yes, when the ABS system detects a problem, it deactivates the ABS and illuminates the light. Be aware: it is still completely safe to drive with the ABS light on. ABS is an electric, add-on system to the brakes. The normal, hydraulic brakes stay completely intact, safe, and functional.
There are a number of sensors on your Explorer. Such as; due to emission controls, you may not have tighten the gas cap or sometimes a sensor can get wet set off the warning light or low oil or ? Since you already paid Auto Zone, see if they can help. In the future, you would be better off going to a good Ford dealer.
The light is on because some reading reaching the computer is not within normal ranges, and the light is telling you the vehicle needs attention. Auto Zone is in business to sell parts, not diagnose vehicle problems. You are correct that the check engine light being on equals an automatic fail in the inspection. Avoid Auto Zone this time, and take it to a competent mechanic who can read the trouble codes and fix whatever the problem is so you can be inspected. Oh, and please don't type in all caps, it's hard to read, and is the cyber equivalent of shouting, which makes it rude also.
If you thought an O2 sensor could set off the ABS light, then you really shouldn't be thinking about replacing a wheel speed sensor yourself.
The O2 sensor is for the ENGINE air/fuel mixture and is NOT your problem! The ABS Light is for the ANTI LOCK BRAKES! Many times it is just because the BRAKE FLUID has spoiled, believe it or NOT! ALL BRAKE fluids SPOIL and turn into SLUDGE, GOO, and CORROSION after about 2 years of use! BENZ says every YEAR! As it absorbs moisture from the air, the BOILING POINT and other , and hose and line rot over time as well as a FAILED MASTER CYLINDER! if EVERYONE changed their BRAKE FLUID on time, they would save THOUSANDS in brake repairs! YOU MAY also have a failed REAR WHEEL SPEED SENSOR but try a FULL FLUID CHANGE FIRST! Many times after getting a BRAKE JOB done, they tamper unknowingly with the ABS SPEED Sensor which is on that REAR WHEEL! Check WHO did your BRAKE WORK and ask them to FIX THIS FOR YOU! But FIRST, have that BRAKE FLUID POWER BLEED and REFILL done! AS the fluid AGES it gets THIN and leaks begin to occur and the SLUDGE and GOOEY BUILDUP will tear apart DUST SEALS and piston seals and ABS seals! ISN'T IT WORTH IT to have it changed then! use ONLY the factory fluids and NOT the crap from the auto part stores! GOOD LUCK TO YOU!
