[Closed] Honda Accord Yellow Light Of Death - Traction Control light??

My bet would be a faulty sensor. Why not take to a deserted wet car park and try and give the traction control a bit of a test ?

Is there any way of knowing whether it's definitely this controller box thingy?

Drive on a load of mud/field/etc, put your foot down and see if it wheel spins would be the simple answer. If the car limits power you still know its working.

Presumably if only one sensor is dead it would only spin one wheel?

I think my dad's more worried about it failing it's imminent MOT based on the light, than anything else!

Sorry, yes I see your point re testing the controller!

The VSA light has been on on my honda accord tourer for around 5 years. The VSA works and it's just a sensor issue within the control box or something like that. The box can be removed and reprogrammed which costs around £150 but obviously it needs to be removed, sent away, reporgrammed, then returned which would leave the car off the road for a while.

Well that depends on how well your dad knows the tester but it technically should be a fail. Whether it is or not is another matter.

As already stated probably just a faulty sensor which will be either the sensor it self of the ring that it is reading. A good fault code reader would tell you which wheel is creating the fault. Swapping sensor from a good wheel to the one that was showing a fault will tell if it's the sensor or ring.

You can get cheap code readers on ebay, that'd be my first step. Get the fault code. In general a wheel sensor is much more likely than the controller.
