Jaguar Throttle Body

What to Do if You Experience Issues with Your Jaguar’s Throttle in Pineville

If your Jaguar frequently stalls, randomly speeds up, or has trouble idling, it may have a problem with the throttle. Issues with your throttle need to be addressed as soon as they appear. Because the throttle is what controls the speed of your car, it could cause damage to your engine or even cause an accident if your car stalls out or randomly speeds up at the wrong time.

What is the throttle?

The throttle is a part of your air intake system. The throttle body is located between the air intake and the intake manifold. Inside the throttle body is a valve called the throttle plate. When you press the gas pedal, it opens the throttle plate. This allows more air to move into the engine. The combustion process gives your engine more power when more air is allowed inside. This increase in power makes your car speed up. If something goes wrong in this process, the engine will be starved of air, and your Jaguar will stall out.

What are the signs to watch out for?

Usually if there is something wrong with the throttle, the check engine light will be on. The check engine light is your car’s way of telling you that it needs some kind of work done, but it’s impossible to tell what the problem is unless you can access the computer itself. The computer sends out codes when something goes wrong. A certified technician has a device they can plug into your car to read the codes. This will tell them exactly what is wrong, so it’s important to take the car to a mechanic if your check engine light is on.

Issues with the throttle body can cause many different problems. Your car might stall out or have trouble idling, and you can expect a decrease in the power and fuel efficiency of your car. If you’re experiencing any of these symptoms, it’s important to get them diagnosed quickly. If your car isn’t getting enough air, it has to burn more fuel, and the engine has to run harder to compensate.

What could be the problem?

Throttle Position Sensor
If your car surges forward randomly and stalls without warning, the throttle position sensor may be the problem. The throttle position sensor tells your Jaguar’s computer when you’re pressing the gas pedal and how hard you’re pressing it. The computer might accidently let too much air into the engine or starve it of oxygen if it is receiving inaccurate signals from a faulty sensor. This can make your car randomly rev up or stall out, even when you aren’t pressing down the gas pedal.

Dirt Build-Up in the Throttle Body
The throttle body needs to be clean and smooth to allow the air to flow into the engine properly. If there is dirt built up inside the throttle body, it can cause the airflow to become disrupted. If your Jaguar is idling poorly, this could be the cause.

Incorrectly Adjusted Throttle Stop
The throttle stop controls how wide the throttle plate opens when you press the gas pedal. If it isn’t adjusted correctly, the throttle plate could open too wide or not wide enough. This could cause your car to speed up faster than you were expecting or stall out when you press the pedal.

Vacuum Leak
If your check engine light is on and your Jaguar idles at high RPM, it could mean you have a vacuum leak. A vacuum leak can cause too much air to go into the engine, forcing it to work harder than it needs to. This lowers performance and increases the wear and tear on your engine.
