If the TCS light turns on in your Honda Accord, it's likely signaling a problem with the wheels or traction control system. A common issue is a malfunctioning wheel speed sensor, which can be diagnosed using an OBD-II scan tool available for free at most auto parts stores. One particular concern with Accords is a blocked EGR port, leading to similar symptoms. Rather than replacing the EGR valve, a simple cleaning of the port and intake manifold is usually sufficient. Honda has issued a technical service bulletin addressing this common problem.
That means there's an issue with the traction control system or a faulty wire that's making the light turn on.
