Can some tell me what sensors the ecu uses to control the idle control valve.
I taking about the bocosh two wire type. I know the ecu earths the valve to make it pulse but what tells the ecu to do that!:runaround:
Please help!

Iac and MAP work together for proper air/fuel mixture and idle rpm example lets say at air intake you supplied propane gas to enter engine the pcm would sense too much fuel and the IAC would open to allow more air to enter intake manifold map would moniter the manifold vacuum and send signal to pcm this then would try to maintain a correct idle speed
