Share on:
  1. step : Accelerator Pedal Release Position Learning (0:15)
    • Do not depress the accelerator pedal
    • Turn the key to the ON position for atleast 2 seconds
    • Turn the key to the OFF position for 10 seconds
    • Turn the key to the ON position for 2 seconds
    • Turn the key to the OFF position for 10 seconds
  2. step : Throttle Valve Close Position Learning (1:00)
    • Do not depress the accelerator pedal
    • Turn the key to the ON position for 10 seconds
    • Turn the key to the OFF position and listen for the throttle body making a whining sound
  3. step : Idle Air Volume Learning (1:41)
    • Run the vehicle up the operating temperature with the vehicle in park, the steering wheel straightened, and the headlights and A/C and other electrical loads off
    • At idle, make sure the vehicle has more than 12.9 volts at the battery
    • Let the vehicle reach up to temp
    • Turn the vehicle off
    • Let the ignition be off for 10 seconds
    • Do not depress the accelerator pedal
    • Turn the key to the ON position and wait 3 seconds
    • Press the accelerator pedal five times in 5 seconds
    • Wait for 7 seconds
    • Check engine light should flash
    • Hold the accelerator pedal down for 20 seconds
    • Release the accelerator pedal within 3 seconds when the engine light stops blinking
    • Start the engine and let it idle
    • Rev the engine a couple of times
    • Confirm the engine returns to the correct idle (around 700 RPM in park for automatic transmission)
    • Confirm there is no check engine light

First step is to perform accelerator released position learning. Do not depress the accelerator pedal. Turn the key on for at least two seconds. So, on for two seconds. Off for ten. On for two seconds. Off for ten. And that should complete that procedure.

To perform the throttle valve close position learning, make sure the accelerator pedal is fully released—so don't put your foot on it. Take the key, turn the ignition on, and wait at least 10 seconds. When you turn the ignition off, you should hear the throttle valve make a whining sound as it returns. That way you confirm that the throttle valve is working.

What we're showing you here with the intake tube off is just what the throttle body is doing during the re-learn process—just to give you a better visual idea.

Now we will perform the idle air volume learning procedure, but before that the car has to meet certain criteria. We need to run it first and get it up to operating temperature and make sure the charging system is putting out at least 12.9 volts.

I'm going to start the car. We're going to let it idle. You want to make sure the headlights are turned off. You want to make sure the A/C is turned off. Basically, no electrical loads. You want to make sure the steering wheel is straight ahead, and that the vehicle is in park.

We're going to let the car come up to operating temperature, and then we'll perform the idle air volume re-learn. At idle, we want to make sure the vehicle has more than 12.9 volts at the battery. It's got more than 12.9 volts, so we're in good shape.

With the vehicle at operating temperature, now we do the idle air volume learning. Now the vehicle is up to temp, and our pre-conditions are met. I'm going to make sure after I shut it off, that the vehicle ignition has been off for at least 10 seconds. It has.

The next step, we're going to turn the ignition on without pressing the accelerator pedal, and wait at least 3 seconds. Now we're going to quickly press the accelerator pedal five times in 5 seconds. Wait 7 seconds. Check engine light will begin to flash. Then you'll hold the accelerator pedal down for 20 seconds. The service engine soon light will stop blinking, and we'll release the accelerator pedal within three seconds.

We'll start the engine. Let it idle. Rev it a couple of times. We'll just confirm that it returns to the correct idle and there's no check engine light on.

So for an automatic transmission vehicle, the engine idle should be around 700 RPM in park or in the neutral position give or take 50 RPM. It looks like we're right about there. When the procedure is complete, you've changed the throttle body.
