ABS light on, needs rear speed sensor and traction control light is on, Do I need to replace these?

What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control. How this system works: Traction control uses wheel speed sensors to detect when one or more of the car's wheels lose grip and traction. When the system registers a loss of traction in one or more of the wheels, a computer will limit power to the wheels that are still in solid contact with the road to prevent a skid. Common reasons for this to happen:

• ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
• Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving. The sensors relay that information to the traction control module, which determines whether or not power needs to be shifted. Wheel speed sensors can get dirty or damaged and stop working, which prohibits the traction control module from knowing when to enable the system.Traction control module is faulty: The traction control module - which, again, is often shared with the ABS - can malfunction and break altogether, causing the system to stop working. What to expect: A top-rated mobile mechanic will come to your home or office to determine the source and cause of the traction control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs. How important is this service? It's important to have the traction control issue investigated as soon as possible, as adverse driving conditions can arise at any time. While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in rain, snow, sleet, or other inclement weather, or even possibly through pools of water on the road. Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS.

The traction control uses the ABS wheel speed sensors (1 on each wheel - usually in the wheel bearing assembly). The speed sensor is for your speedometer. Do you have an ABS light on too?

there should be one speed sensor for every wheel some speed sensors are located in the wheel hub

This usually means that there is a problem with one of the wheels speed sensors. You will need to have the vehicles ABS codes scanned to figure out what one is needing to be replaced.

well while putting the car on the lift, traction control does not need to be disabled, and will not cause the abs/traction light to illuminate, these cars are known to have terrible wheel speed sensors that are brittle and tend to brake or malfunction for no apperent reason, and the wheel speed sensors are what control your abs and traction conrol units and they are normally what make the light come on on your dash, the warranty on the sensors was prolonged for that reason, so depending on the mileage of your car they might be covered, hope this helps

Had the same problem with my 2002 Lincoln LS, it was a bad wheel speed sensor. The right front wheel bearing had some play in it, so I had the hub assembly replaced. The hub assembly comes with a new wheel speed sensor attached. After I replaced the hub assmbly with sensor, the ABS and Traction Control lights went off. No problem since!

The ABS sensor is a speed sensor also for Traction Control. This is why both lights are on , One of your front ABS sensors are bad or disconnected, or has a pinched wire.

If the ABS (and likely the traction control) light came on at the same time that the speedometer stopped working, you likely have a faulty wheel speed sensor at the right rear wheel. You can test this by swapping the two rear wheel speed sensors (ABS sensors). If the speedometer then works (but the ABS & Traction control lights stay on), replace the sensor that is now at the left rear (was at the right rear). If no change, you may have a fault in the ABS & Traction control - control unit.
