What would cause the traction control light to stay on?
In some cases, the warning light can come on because wheel-speed sensors are covered with road grime or debris. When the traction control warning light stays on, that means you aren’t getting any help from the system to control traction and the system needs to be checked.
How do you clean a traction control sensor?
If you need to, use warm, soapy water to scrub away dirt from the sensor—just make sure that the sensor dries completely before you replace it. Use a wire brush or file to gently grind away stubborn rust or dirt. Be careful if you do choose to do this, as excessive cleaning could damage the sensor.
How do I know if my wheel speed sensor is bad?
Common signs include the ABS Light coming on, ABS not working properly, and the Traction Control Light staying on.
Can a bad battery cause traction control light?
A weak battery or one with low voltage can inadvertently cause other warning lights to come on, including the ABS and Traction Control lights. When your car’s alternator is not working properly, the occurrence may cause the battery to lose charge and the car losing all power.
What should I do if my traction control light comes on?
If the traction control light comes on while you’re driving, but no other warning lights are illuminated, don’t panic. Find a safe place to pull over, turn off your vehicle, and then restart it. If a fluke in the TCS system triggered the warning light, it should turn stay off when you restart the engine.
What does it mean when your traction control is not working?
When your car is in a difficult terrain and the traction control light is on, it means that the stability system works and it is safe to drive. But with the same terrain and the light does not turn on, it means the traction control system is now not working.
Can a bad speed sensor cause traction control to come on?
However, if the wheel speed sensors are not working as they should, then the traction control system may not be notified. The vehicle can then start to lose traction, which results in the traction control light coming on. If the wheel speed sensor is faulty, it can also cause your ABS or brake light to come on as well.
How does traction control work on a Honda Accord?
Your TCS is controlled by a set of wheel speed sensors, located at each wheel, and shared with your ABS system. These sensors provide a constant flow of information to your traction control computer about whether each wheel is rolling normally, or if it is slipping or spinning.
