How do I Clean my throttle body?
How do I clean my throttle body? Follow the plastic duct from the air filter housing up to the throttle body. Remove the duct and locate the throttle cables and rotating mechanism. Rotate the throttle mechanism and spray the cleaning solvent around the inside of the throttle body. Give it a moment to work and then wipe out the crud.
How do you reset throttle body after replacing?
Leave the key off for a moment, turn the key to the "On" position again, wait 3 seconds, and press the accelerator 5 times in 5 seconds. Wait 7 seconds, and hold the accelerator down. The check engine light should start blinking, continue to hold pedal down until it stops blinking. You can then start the car.
How do you reprogram a throttle body sensor?
How to Reset Throttle Position SensorPut the key in the ignition.Turn the key to the On position, without cranking the engine. Wait a few seconds, then turn it off.Repeat the second step.Crank the engine.Pull the parking brake.Set the gear lever in Drive.Wait 5-10 minutes.
What happens if you don't relearn your throttle body?
What happens when you replace the throttle body? If you replace the throttle body, the PCM won't know and will continue to use the adaptive settings as if the carbon buildup is still in place. If you don't do a relearn procedure, the PCM will “hunt” for a new baseline idle.
How do I reset my electronic throttle position sensor?
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Do you have to reset computer after replacing throttle position sensor?
After replacing the throttle body to your engine, if the engine light was on and has a pending code, the code will go away. If the code was a hard permanent code, then the ECM (computer) would need a hard reset.
Does a throttle body need to be calibrated?
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. First, be sure you have correctly wired, and assigned the throttle sensor signal input to "TPS Raw" in the Analog Settings.
Does an electronic throttle body need to be programmed?
In fact, on some engines a new throttle body needs to be programmed with a factory, or equivalent, scan tool. The technician cannot even clean the carbon out of the throttle body in some cases without setting a "check engine" light.
Do you have to calibrate a throttle body?
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. First, be sure you have correctly wired, and assigned the throttle sensor signal input to "TPS Raw" in the Analog Settings.
How do I calibrate my accelerator pedal position sensor?
To calibrate the accelerator pedal assembly: To recalibrate the ECM and accelerator pedal, the ignition switch must be in the ON position and then the accelerator pedal must be slowly and fully depressed from idle to full throttle. Repeat the procedure three times.
What does the pedal do on a throttle?
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.
How long to let a PCM idle?
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.
When did Ford start using fly by wire throttle bodies?
Starting in early 2000’s , many car makers including Ford started installing fly by wire electronic throttle bodies.
How do you recalibrate a throttle body?
Accelerator Pedal Release Position Learning Procedure. Make sure that the accelerator pedal is fully released. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds.
Does a new throttle body need to be reprogrammed?

How do I reset my throttle position sensor?
This step can also be necessary when you install a new sensor. The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Do you have to calibrate a throttle body?
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. The signal on the chosen pin should sweep from approximately zero to five volts as you move the throttle from fully closed to fully open.
What happens when you unplug throttle position sensor?
The TPS as we call it is one of the most important sensors on the engine. Without it, the computer has no way of knowing when you push down on the gas or open the throttle. Best it can do it watch some other sensors and make some estimated guesses. On some cars, it may burp just as you unplug it if it’s running.
How do you relearn a Ford transmission?
