So your mechanic tells you that you need a new throttle bypass valve. The good news is that it's easy to find replacement throttle bypass valves on the market. The "not-so-good" news, however, is that not all bypass valves are designed for your specific intake bypass system. There's a danger of going for the wrong valve and trying to use it. Not only will your intake bypass system fail in rerouting airflow in your engine assembly, it can also lead to poor overall vehicle performance. Save yourself and your wallet from the hassle of buying the wrong bypass valve. Make sure that the throttle bypass valve you're eyeing is right for your ride by buying a direct-fit and OE-style replacement component. So how will you know if the valve you're checking is compatible with your intake bypass assembly? Well, first, you can use your original equipment's part number to locate the best valve for your car. If you can't find this valve's part number, then another way is by using the Auto Parts Warehouse "Shop by Vehicle" function. By giving us info about your car's year, make, and model, we'll be able to filter the throttle bypass valves we're showing you.

How to Replace a Worn-out Throttle Bypass Valve

Your Ford suddenly dies whenever you take your foot off the gas, emits a loud humming noise from the engine bay, and can sometimes be quite difficult to start-these are the signs of a dirty or broken throttle bypass valve. The throttle bypass valve, sometimes called intake air control valve, is a small metal part under the hood that controls the air that goes into your engine, allowing your car to idle properly. If this valve gets dirty or broken, air won't flow smoothly through your engine and your car will have a hard time idling. Luckily, cleaning and replacing the throttle bypass valve on your Ford is a cheap and easy job even for amateur DIYers.

Difficulty level: Easy

Things you'll need:

  • Socket and wrench set
  • Rags and cotton swabs
  • Electrical part or carburetor cleaner
  • Replacement throttle bypass valve
Warning:

For your safety, always disconnect the negative terminal of your battery whenever you're working on any part of your vehicle that involves electricity and wiring.

Step 1: Park your vehicle on a level surface, pop the hood open, and let the engine cool down.

Step 2: Locate the throttle bypass valve on your engine bay; different models will have different orientations.

Step 3: Pull out the electrical connector attached to the valve.

Step 4: With your wrench and the appropriate socket, remove the bolts that hold down the valve.

Step 5: Clean the chambers where you took out the valve from using your rags, cotton swabs, and cleaner.

Step 6: Place the new throttle bypass valve along with a new gasket. Put the bolts in and tighten them securely.

Step 7: Reattach the electrical connector.

Step 8: Reconnect the negative terminal of your battery.

Cleaning and replacing your throttle bypass valve only takes about 30 minutes. Don't forget to test your vehicle's idling to see if you have properly replaced your throttle bypass valve.
