Ford throttle body relearn procedure

How to do a Ford throttle torso relearn procedure

If you've replaced your Ford electronic throttle body or you've disconnected the battery, you lot must practice a Ford throttle body relearn to establish a new baseline idle. image of a ford electronic throttle body Starting in early 2000's, many motorcar makers including Ford started installing wing by wire electronic throttle bodies. In those vehicles, the "gas" pedal isn't connected to the throttle body by a cable. The pedal but provides an electronic signal, telling the throttle trunk how much acceleration you're requesting. A motor and gear reduction prepare inside the throttle body opens and closes the throttle plate to accomplish your request.

Over time, carbon buildup can accumulate effectually the throttle plate, changing it's "home" position. If the buildup occurs gradually, the PCM "learns" the new abode position. Simply when your battery goes dead or yous disconnect it to work on your vehicle, the PCM "forgets" the adapated dwelling house position. If you don't do a relearn process, the PCM will "hunt" for a new baseline idle. It will eventually learn it on its own, but it may take over a calendar week of driving, during which time yous volition experience loftier and low idle speeds and possibly crude idle.

Articulate the PCM adaptive memory

one) Disconnect the negative battery terminal.

2) Run a jumper wire from the positive battery cablevision to the now disconnected negative battery cable terminal. Note. Practise this with the negative cable DISCONNECTED from the battery. The short circuit you're creating hither is designed to drain all power from the capacitors inside the PCM. Leave the jumper connected for about ii-mins.

three) Reconnect the negative battery cablevision to the bombardment.

Turn off all electric accessories before proceeding. Turn off headlights, blower motor, radio, wipers, etc.

4) Plow the key to run and wait for all warning lights to plow off. During the catamenia the PCM volition control the throttle body plate to sweep from total open to full close to "acquire" the new positions.

5) Start the engine and allow it idle for a total x-mins until it reaches full operating temperature. During this flow the idle may be higher than normal. It should slowly drop equally the engine heats upward. Watch the engine temp judge and notation when it reaches operating temp. And so continue to allow it idle for an additional five minutes. It will continue to accommodate idle during this period.

six) Bulldoze the vehicle at various speed so the PCM learns shift points.
