Your RPMs will go up and down lower with passing time then your vehicle will eventually start to shut off. You will only be able to drive it by keeping your foot on the accelerator
idle air control motor where is it located
The idle is control by the idle air control motor from outputs from the Engine Control Module.
The computer uses a motor in the throttle body assembly to open the throttle plate. There isn't a separate idle air control motor.The computer uses a motor in the throttle body assembly to open the throttle plate. There isn't a separate idle air control motor.
Idle air control motor or IAC
There is no such thing as an idle air control sensor. The idle air control module or motor is located on the side of the throttle body assembly facing toward the engine.
The idle is adjusted by way of the Idle Air Control motor as directed from the Engine Control Module. The idle is computer controlled. I changeTHE IAC motor for a new one ,still there is a bit of a rough Idle, what can be the trouble
underneath the throttleboby
it mounted on the throttle body
Idle speed on a 1995 Chrysler Cirrus is controlled by the PCM. The PCM operates the idle air control motor. The PCM adjusts engine speed through the idle air control motor to compensate for engine load, coolant temperature or barometeric pressure changes. The Idle Air Control (IAC) motor is mounted on the throttle body and has an air bypass passage that provides air for the engine during closed throttle idle. The idle air control motor pintle protudes into the air bypass passage and regulates air flow trough it. The PCM adjusts engine idle speed by moving the IAC motor pintle in and out of the bypass passage. The adjustments are based on inputs the PCM receives. The inputs are from the throttle position sensor, crankshaft position sensor, coolant temperature sensor, MAP sensor, vehicle speed sensor and various switch operations. Hope that helps.
The idle air control valve is located on the side of the intake manifold right next to the throttle body
The idle air control valve on a Saturn SC1 is found on the intake manifold. This valve controls how much air enters and engine and allows how high the motor can idle.
The idle air control valve is a stepper motor which regulates the amount of air entering the engine during idle and other times during an engine's run period, such as deceleration, or when the A/C compressor is in use.
