This particular vehicle does not have an IAC valve. This is because it is equipped with ETC (Electronic Throttle Control). This means there is no mechanical connection between the accelerator pedal and the throttle plate. Instead, the throttle plate is controlled by an electric motor to control its engine speed, based on ';input'; it receives from the PCM. The accelerator pedal is connected to three poteniometers. Two that increase, and one that decreases voltage in a particular proportion. If they fail, the vehicle goes into what's called a ';forced idle'; mode of operation. Hope this helps.Where Is the Idle Air Control Valve on a 2004 F150 5.4L 3V V8...any help would be greatly appreciated?
