Dodge refers to this part as a linear iacv solenoid (commonly known as idle air sontrol motor), it should be located on the firewall side of the throttlebody. The factory dodge part# you need is 4861552ac $83.20 available within a day or two.Where is the idle air control valve located on a 2004 Dodge Ram, 4.7l engine?
on the side of the throttlebody

Does a bad idle air control valve cause pour starting?
ya it can start rough and either die or run badDoes a bad idle air control valve cause pour starting?
Kind of. If it wasnt working the motor would immediatley die after intially starting. I.E. It wouldnt Idle.

Is the idle speed sensor the same as the idle air control valve on a 93 ford tempo?
Probably - although it's a misnomer.
The IAC or Idle Air Controller does the actual controlling of the idle speed while an idle speed sensor would indicate the actual idle speed input to the computer.Is the idle speed sensor the same as the idle air control valve on a 93 ford tempo?
no one is a sensor and the other is an actuater. idle speed sensor tells the computer how fast the engine is turning, and the computer tells the idle air control valve to open or close to correct idle speed.

I own a 1999 Ford F-150. My mechanic says I need to replace the Idle control air valve. What does this valve?
do and what does a defective one do to my idle speed and rpms? The motor is a 4.2 litre V6. Thanks, CurtI own a 1999 Ford F-150. My mechanic says I need to replace the Idle control air valve. What does this valve?
This is a computer controlled, electronic stepper motor that is used to control the idle speed. There is a target idle speed in the powertrain control module and it uses this motor to control the size of an orifice that bypasses air around the throttle plate. Increasing the amount of air (opening the valve), will increase the idle speed, while decreasing the amount of air (closing the valve), will decrease the idle speed. The PCM uses various sensor inputs to tell how fast the air is going, as well as to tell if the air/fuel mixture ratio is correct. A defective valve can have several symptoms. If it is stuck open, then it can cause a high idle or dying problem, if stuck closed it can cause low idle or for the vehicle to die. If it is slow to respond it can cause and idle hunting condition, like when it goes up and down. If it gets stuck in a certain position it can cause erratic idling. The valve also opens and closes, even when accelerating, decelerating and cruising to make the changes more smooth, and it can have performance affects even above idle.I own a 1999 Ford F-150.

The idle air motor does just that!It controls the idle. A bad one could cause stalling or erratic idle
The Idle Air Control valve (IAC) controls the engine idle speed. The output actuator is mounted on the throttle body and is controlled by voltage pulses sent from the PCM (computer). The IAC valve pintle moves in and out allowing more or less intake air into the system according to the engine conditions. To increase idle speed, the PCM retracts the IAC valve pintle away from the seat and allows more air to bypass the throttle bore. To decreaseidle speed, the PCM extends the IAC valve pintle towards the seat, reducing the air flow. To check the IAC valve unplug the electrical connector and, using an ohmmeter, measure the resistance across terinals A ans B, then terminals C and D. Each resistance check should indicate 40 to 80 ohms. A bad IAC will cause the engine to run rough, stall, hard to start. The engine can die when driving and make you mad enough to slap your moma. It can be dangerous to drive.

the idle control air valve main job/func you can noticed is when starting the engine in the morning.. did you noticed the idling of your car is a bit high? after 1-2minutes it all came to normal idling rev.. and when turning on the air-condition.. theres a slightly change in the RPMs.. why? its simple the idle control valve make sure your engine turn on.. rather than stepping on the gas pedal all the time
Its your air sensor for whats coming into the car, its something you can change yourself.
This is a common problem on Ford V8s.. The good news is that it is simple and cheap to replace. It is a small electric air control valve that is attached to your throttle body. It lets a regulated amount of air flow behind the closed butterfly when the throttle is closed so the truck can idle. When they get stuck you idle rough or the truck is hard to start or keep running at idle.. I think the part is about $60 US and you can just bolt on a new one in 15 minutes.. Hope this helps.

What is the difference between flow control and pressure reducing valve?
any difference in application of stem,fluid of these valvesWhat is the difference between flow control and pressure reducing valve?
None. The only difference is the controlled variable. All valves are flow control elements. The controller attached to the valve tells the valve what to do.
If it is a pressure control valve, the pressure sensor signal will be compared to a setpoint and move the valve to open or close. Same if it is a flow control valve, except that you will have a flow meter instead.
Addendum - Remember you cannot control the pressure in ';solid'; (liquid only systems).

.What is the difference between flow control and pressure reducing valve?
The difference is which process you are trying to control. A flow control valve is maintaining a desired setpoint of flow and a pressure control valve is maintaining a desired setpoint for pressure. Usually the best type of valve for controlling flow is a globe valve and it is used in all applications. Many types of valves are used for pressure control, but the most common is probably a gate valve.
Oh, and steam is a fluid
pressure and flow are two different things. a flow control valve controls the ammount of flow to a device i.e. steam turbine control valves. a pressure reducing valve reduces pressure to the user i.e. regulator on an airsystem used to drop instrument air to a useable pressure.

What does idle air control valve do on a ford pickup?
my answer is try to check it out on auto repair shop..What does idle air control valve do on a ford pickup?
messes stuff up..lol
its supposed to control the emount of air it lets in while its idleing as i recall..but im a chevy guy and im an anti-computer in cars guy so ...i could be a bit biased also ;)What does idle air control valve do on a ford pickup?
it controls the right amount of air to the amount of gas its getting.one web hosting

Where is the HEATER CONTROL VALVE on a 1997 FORD EXPEDITION with a 4.6L engine?
Your truck doesn't have a heater control valve. It has heater hoses that run hot water straight into the heater core on the back of the engine on the passenger side. If your are having a problem getting heat inside the truck, but the gauge shows heating up ok, then you probably have a bad blend door or blend door actuator...Where is the HEATER CONTROL VALVE on a 1997 FORD EXPEDITION with a 4.6L engine?
there is not one there is a blend door motor that changes from cold to hot very common problem that it goes bad
