The Engine Management System (EMS) on your Ford Focus uses the Idle Air Control (IAC) valve to adjust idle speed. This valve works in combination with other electrical components. However, carbon buildup on the valve port passages affects its operation. In addition, a malfunctioning IAC valve may have a direct impact. The VSS in a 2001 Ford Escape is located on the left rear side of the transmission. There is only about an inch of it that can be seen. The idle air control is a cylinder with a wire connector.

. 14 AnswersSOURCE:If it's not idling and has problems starting, it's probably the IAC motor.

It's located on the throttle body. Follow the airfilter box all the way to the engine, where the rubber flex hose attaches.

The throttle body should be the first aluminum part you come to. Attached to the side you'll find small little aluminum part with a small wire harness attached. Unplug it, take the IAC motor off and clean inside with carb cleaner. This should fix the problem with the idle.Posted on Sep 11, 2009.

Ford throttle body relearn How to do a Ford throttle body relearn procedureIf you’ve replaced your Ford electronic throttle body or you’ve disconnected the battery, you must do a Ford throttle body relearn to establish a new baseline idle. Starting in early 2000’s, many car makers including Ford started installing fly by wire electronic throttle bodies. In those vehicles, the “gas” pedal isn’t connected to the throttle body by a cable. The pedal simply provides an electronic signal, telling the throttle body how much acceleration you’re requesting.

A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request.Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position. If the buildup occurs gradually, the PCM “learns” the new home position. But when your battery goes dead or you disconnect it to work on your vehicle, the PCM “forgets” the adapated home position. If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle.

It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle. Here’s a post on how to Here’s the throttle body relearn procedureClear the PCM adaptive memory1) Disconnect the negative battery terminal.2) Run a jumper wire from the positive battery cable to the now disconnected negative battery cable terminal. Do this with the negative cable DISCONNECTED from the battery. The short circuit you’re creating here is designed to drain all power from the capacitors inside the PCM.

Leave the jumper connected for about 2-mins.3) Reconnect the negative battery cable to the battery.Turn off all electrical accessories before proceeding. Turn off headlights, blower motor, radio, wipers, etc.4) Turn the key to run and wait for all warning lights to turn off.

During the period the PCM will command the throttle body plate to sweep from full open to full close to “learn” the new positions.5) Start the engine and let it idle for a full 10-mins until it reaches full operating temperature. During this period the idle may be higher than normal. It should slowly drop as the engine heats up. Watch the engine temp gauge and note when it reaches operating temp.

Then continue to let it idle for an additional 5 minutes. It will continue to adjust idle during this period.6) Drive the vehicle at various speed so the PCM learns shift points.©, 2015 Rick MuscoplatSaveSave.

Eautorepair.netAllDataDIY.comGet the BEST auto repair information and are the two best shop manuals—period! Unlike the cheaper Haynes and Chilton manuals that cover multiple year models, leaving the exact information you need to fix your car, these professional manuals cover your exact year, make, model.

If you’re tracking down a wiring issue, is the better choice. Eautorepair.net redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams. That saves a lot of time because you don’t have to refer back to the component locator or circuit locations. Alldatadiy.com, on the other hand, uses the factory diagrams. So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations.

However, also includes disassembly instructions for interior trim panels and exterior items like headlights and tail lights. If you need to dig into your doors, dash or console, Alldatadiy.com is the better choice because Eautorepair.net doesn’t any interior or exterior trim or body part removal.
