When is the throttle body plate stuck in the closed position?
When is the throttle body plate stuck in the closed position?
Code P2112 is set by the PCM when the throttle body plate is stuck in the closed position. The PCM controls the Throttle Actuator Control System by monitoring one or more throttle position sensors.
What kind of throttle body do I need for TBSs intake?
The TBSS intake also will require a 4-bolt mounting throttle body. The early truck manifolds used a 3-bolt throttle body so it will not transfer–unless you want to purchase an adapter. We’ve listed one from ICT Billet in the parts list section. The least expensive 4-bolt throttle body we found is a Holley Sniper 92mm version.
Where does fitech attach to the throttle body?
As for the ECU, FiTech mounts it directly to the throttle body, and all necessary sensors are either part of the throttle body – like air temperature, throttle position sensor, idle air control valve, and fuel injectors – or they are included, such as the wide band O2 sensor and the cooling temperature sender.
How does the PCM control the throttle body?
The PCM controls the Throttle Actuator Control System by monitoring one or more throttle position sensors. The operation of the throttle body is determined by the position of the throttle plate that is controlled by one or more Throttle Actuator Control Motors.
Can a swap stock throttle body be ported?
A You can definitely do that, reason for keeping the swap stock and not ported for now is the cost of tuning on the newer vehicles, but if your get it all do together then yes, porting would be the way to go. Give me shout and i can give you more details.
When do you know your throttle body needs cleaning?
When your throttle body is operating below its normal effectiveness, one of the tell-tale signs is a poor or low idle. This includes stalling after coming to a stop, a low idle after starting, or stalling when the throttle is pressed down rapidly. Dirt causes airflow into the system to be turbulent and leads to a fluctuating idle speed.
Is there a way to reset the throttle body?
This method is almost foolproof as long as all ECU control parameters are within their normal ranges. Resetting The Throttle Body Calibration (this step is conditional) A Rough Idle or a SES can sometimes be caused by a change in the throttle body position sensor calibration.
What happens if your throttle body is covered in dirt?
If the throttle body’s electronic sensor is covered in dirt or grime this will result in faulty or unnecessary corrections to the air-fuel mixture, which could put the car into a secondary power reduced mode until it gets seen by a service mechanic.
How to relearn the Ford throttle body?
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.
What causes the throttle to not close properly?
As vehicles go up in mileage and over 100k, they can get excessive carbon buildup around the throttle body plate. This can allow the throttle to not open or close properly, or become stuck open or closed. Throttle body cleaners can be used sparingly to clean the carbon buildup and restore proper throttle plate function.
What was the problem with the Ford throttle body?
Obviously, doing so is dangerous. In our complaints, the problem was diagnosed as a failed throttle body, with trouble codes P2111 and P2112 present in the on-board computer system, indicating the electronic throttle actuator control system was stuck open and closed, respectively.
Code P2112 is set by the PCM when the throttle body plate is stuck in the closed position. The PCM controls the Throttle Actuator Control System by monitoring one or more throttle position sensors.

How does a GM throttle body relearn procedure?
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.
