This is usually at the front of the engine area and connects to the air filter housing.The throttle body is a key part of this system and lets air into the engine. In most Chrysler cars, it's placed on the intake manifold, located between the air filter and the engine. It typically looks like a metal or plastic piece with a flap inside, which is moved by the gas pedal.Here's a quick guide:Air Intake System: At the front of the engine, links the air filter to the throttle body.Air Filter: Inside the air filter housing, cleans the air coming in.Throttle Body: On the intake manifold, manages air going into the engine.Intake Manifold: Sits between the throttle body and the engine, sends air to the engine's cylinders.Butterfly Valve: Found inside the throttle body, adjusts air flow based on the pedal.This setup helps you see where everything fits in the air intake system of your car.Remove Air Intake ComponentsTo clean the throttle body on your Chrysler, first, you need to take off the air intake parts. This lets you reach the throttle body easily. Here's how to do it:Disconnect the Battery: Use a wrench to take off the cable from the battery's negative side. This keeps everything safe from electrical issues.Loosen Clamps: Find the clamps holding the air tubes to the throttle body and air filter box. Use a flathead screwdriver or socket wrench to loosen them.Take Out the Air Filter Box: Gently pull the air filter box away from where it's attached. You might need to wiggle it a bit to get it loose.Remove Intake Tubes: Carefully take off the intake tubes from both the throttle body and the air filter box. Be careful not to harm any sensors or parts connected to it.These steps will give you a clear path to clean the throttle body.Inspect the Throttle BodyBefore you start cleaning, take a good look at the throttle body. Check the throttle plate and the inside walls for any dirt, rust, or damage. Use a flashlight to see the hard-to-reach areas.Make sure to check the throttle shaft and its bushings. If they are too loose or stuck, you might need to replace them instead of just cleaning.Look at the wires and connections for the throttle position sensor (TPS) and the electronic throttle control (ETC) motor. Check for any loose wires or rust that could cause problems. These parts need to work well for the throttle body to do its job.If you have a diagnostic tool, use it to scan for trouble codes related to the throttle body. Codes like P0121 or P2111 can show there are issues that need more checking.This helps find problems early so the throttle body works well after you clean it. A careful look will help you decide if cleaning is enough or if you need to fix more things.Clean the Throttle BodyTo clean the throttle body in your Chrysler, follow these simple steps to help your engine run smoothly. Over time, dirt and carbon build-up can block airflow, which can cause problems. Here's how to clean it:Gather Your Tools: Get a clean microfiber cloth, a spray can of throttle body cleaner, and a soft brush. These will help you clean without causing any damage.Prepare the Area: First, disconnect the car battery to protect any electronic parts. Then, take out the air intake duct to get clear access to the throttle body.Clean the Throttle Body: Spray the cleaner on the throttle plate and nearby areas.

Look for any damage or wear that might cause leaks. Check the hose clamps and change them if they're not holding tight.Tighten the bolts that hold the throttle body to the intake manifold. Use a torque wrench, if you have one, to tighten them between 15 to 22 foot-pounds.Finally, connect the negative battery cable again. This helps the car's computer adjust to the clean throttle body.Follow these steps carefully, and everything should work well.Test Your VehicleTest Your VehicleOnce you've put everything back together, it's time to make sure your vehicle works right. This will show if cleaning the throttle body helped and if all parts are in place.Here's how to check your vehicle:Start the Engine: Turn on the car and let it sit for a bit. Listen for strange sounds or feel for vibrations that might mean something's not right.Check Acceleration: Press the gas pedal slowly to speed up the engine. It should rev up smoothly without any stuttering if the throttle body is clean and working well.Drive the Car: Take a short drive. Watch how it speeds up and slows down to see if it runs smoothly.Look at Dashboard: Check if any warning lights, like the check engine light, turn on. If no lights are on, there are likely no problems with the throttle system.People Also AskHow Often Should the Throttle Body Be Cleaned on a Fuel-Injected Chrysler?Clean the throttle body on a fuel-injected Chrysler every 30,000 to 60,000 miles.
