Idle Control Valve E30 at Kate Mackinlay blog

Idle Control Valve E30. I have the motronic system with the three pin icv (idle control valve). As far as i am aware idle. Replace the idle control valve if inoperative. The idle control valve maintains the idle speed by controlling the amount of intake air when the throttle plate is closed. Idle or hard starting problems are most commonly caused by intake leaks and/or a sticky or defective idle control valve (icv). You can remove the idle motor and install an orifice to test this theory. High idle or most idle issues e30 models are usually caused by a combination of a faulty idle valve and idle control unit. A faulty icv may cause. If i pull off the plug to the icv with the engine at idle nothing changes! More research done, and it would appear that the transistors that control the idle valve in the ecu are kaput. It should simply open the icv by putting voltage across it and letting air bypass the closed throttle body.
