TCS Control Valve Assembly
The TCS control valve assembly consists of the TCS control valve actuator (DC motor), TCS control valve sensor, TCS control valve, return spring, and three gears.
When the TCS is activated, the VSA control unit signals the TCS control valve actuator and PCM. The actuator is linked to the TCS control valve which is normally held in the fully open position by the return spring. Although the throttle valve is still within the driver's control, the engine output is reduced by the TCS control valve and PCM to achieve optimum traction.
