Vehicle Stability Assist-Traction Control System Control Valve Assembly
The Vehicle Stability Assist-Traction Control System (VSA-TCS) control valve assembly consists of the VSA-TCS control valve actuator (DC motor), VSA-TCS control valve sensor, VSA-TCS control valve, return spring, and 3 gears. When the TCS is activated, the VSA control unit signals the VSA-TCS control valve actuator and the PCM. The actuator is linked to the VSA-TCS control valve which is normally returned to 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 VSA-TCS control valve and the PCM to achieve optimum traction. See Fig 1 .
