Ford Explorer Throttle Body Problems

The throttle body is a crucial component of the induction system in contemporary fuel-injected automobiles. It regulates the airflow into the combustion, which is utilized to consume gasoline in the pistons efficiently. It’s important to absorb the proper quantity of air. 

So, why do ford explorer throttle body problems happen?

Internal contamination is one of the key reasons why a throttle body malfunctions. The control valve could no longer move correctly as a result of the pollution. Your engine may run lean if there is too much or not enough air. As a result, the throttle valve could no longer move correctly.

The accelerator pedal, fuel intake, and throttle body are all coordinated whenever the carburetor is operating properly. When you depress the pedal, more fuel is pumped into the engine. And the carburetor draws in more air to help with combustion. 

That will improve your car’s performance and make it operate more smoothly. Let’s explore more regarding the throttle body problem of the Ford Explorer.

Causes and Solutions of a Throttle Body Problem

Your Ford Explorer may run horribly if the throttle body is damaged. Dirt and filth, the engine light signal, and an inconsistent idle are typical signs. These are the indications of a malfunctioning throttle body.

The throttle body on your Explorer regulates how much air gets into the engine. The gas pedal is used to alter the throttle body position. Therefore, the signs of a damaged throttle body will have an impact.

This will impact how the car responds to the throttle input. Another typical sign is a harsh idle. A filthy, blocked, or broken throttle body prevents air from entering the engine.

This somewhat affects performance. This may also result in unburned gasoline going through to the exhaust system. You may spot this problem before it gets worse.

Just keep an eye out for the symptoms listed below:

Warning: Service Engine Soon

If the engine light is on, we highly advise the users to start with it. One of the most typical signs of a damaged throttle body in the Explorer. This is the check engine light. 

Being aware of the engine light signal is not a problem. The computer’s recorded error codes may provide a wealth of information. It will tell you about what is really happening. 

This greatly simplifies the diagnosis of the throttle body. You’ll want a diagnostic scanner to extract these data from your Explorer. You may get one at a decent cost. 

Or you might visit the neighborhood car parts shop. The majority of them could be delighted to connect a code scanner. They will explain why the fixed engine shortly light is still on

And they will give you the code number. When you have this knowledge, you may research the costs and complexity of correcting it. Most of the common error codes are P0300, P0171, P0420, etc.

Here we have something which may become handy for you:

You’ll learn what frequently sets off the specific code as well as how to resolve it. Then you may decide if you have the mechanical know-how necessary to undertake the repair. Or whether you need to give up and take it to a shop.

You are completely in the dark without these codes. Restoring the Ford Explorer to its which was before the condition is the only way. Then you’ll be capable of turning off the check engine soon light. 

Shortcuts are not available. But it could be worthwhile to examine the gas cap. If the screw wasn’t tightened or it appears to have a faulty seal. Then driving for a time after tightening the screw may cause the warning light to go off.

Throttle Body That Needs Cleaning

You could notice that the Explorer seems like it starves to death when come to a halt. Up to 500 RPM may be suddenly increased before the idle speed is reached. This is a blatant indication that the throttle body is unclean.

It might be wise to check its throttle body and see if any filth has accumulated there. The throttle body isn’t always “bad,” either. It’s just filthy. 

Many of the signs of a damaged throttle body will be present in a filthy throttle. Make careful to use throttle body cleaning rather than carb cleaner, brake parts cleaner, or even WD40. It is inexpensive and simple to clean.

Even if your automobile has an air filter, soot, and dirt. There may still become lodged in the throttle body nozzle from the turbo. Also from EGR valve, and crankcase ventilation. 

After a while, it will completely block the valve, affecting the RPM. A filthy throttle body valve contributes to a variety of throttle body issues. It is frequently possible to clean it. 

You may read our article on cleaning the throttle body here to learn more about cleaning it. But don’t forget to use a diagnostic scanner to recalibrate the throttle body after that.

Instead of replacing a throttle body, you may save a lot of money by cleaning it.

Problems With Wirings

The different sensors in the Explorer monitor the air entering it and the oxygen content leaving it. It happens when the throttle body opens. It may feel like a faulty throttle body if one of these sensors malfunctions. 

Obtaining the difficulty codes is crucial for this reason. It may help you find exactly what you’re searching for. Electronic wiring acts as the nerve system of a contemporary automobile.

So many of its functions depend on digital connections and controls. If the electronic sensor in the throttle body is coated with dirt or filth. The air-fuel mixture will be incorrectly or needlessly corrected. 

That might place the vehicle into a secondary power-reduced mode. It can happen until it is tended to by a service technician.

The throttle body assembly should be the first place you check. As you’re having any of the issues on this list. The first way to start with this system is with a good cleaning up.

There should not be any extra dirt or crud on the interior housing walls. Before beginning the cleaning procedure you need to determine one thing. Determine if the throttle body is manually or electronically operated by consulting your owner’s handbook. 

You may be capable of cleaning a mechanically run system yourself. But for electronically controlled systems, you’re better off hiring a licensed technician.

Throttle Body Replacement Procedure

Make sure to do all of the steps. If required, the engine hood should be taken off. The air intake housing to the throttle body flexible rubber snorkel is detached. Usually, a sizable stainless steel pipe clamp is used to secure the connection.

The throttle body’s electrical connections have been cut off. The accelerator wire and power steering cable are cut off. And put aside if the throttle body would not be a drive-by-wire system.

The gasket, the bolts holding the throttle body towards the chamber. As well as the throttle body is all taken off. Approved cleaning agents are utilized when the throttle body has been cleaned and checked for reuse.

Reattaching the throttle body to the plenum after repair. Replacement requires tightening the bolts to factory standards. Electrical connections and wires are all back in place. 

Reconnect the intake air snorkel. If necessary, a suitable scan tool is used. It’s used to carry out the installation of the electronic throttle and the idle re-learning operations.

The engine is then started, and warmed to the proper operating temperature. And the idle speed is tested. To guarantee proper functioning and the absence of any warning, the vehicle is put through a road test.


Here are some of the questions that are asked quite often-

Is Driving With a Damaged Throttle Body Safe?
