TCS Control Valve Actuator

TCS control valve actuator is normally in a fully open position. Amount of wheel spin is controlled by increasing or decreasing engine output. When TCS is activated, TCS control unit signals TCS control valve actuator and PCM. TCS control valve actuator will be closed, fuel flow will be reduced and ignition timing will be retarded, causing engine output to be reduced. Control of throttle valve is still maintained by driver.
