How to Clean Throttle Body Assembly 02-08 Dodge Ram

Difficulty: Beginner · About 45 min · Dodge Ram

Clean carbon deposits from the throttle body on a 2002–2008 Dodge Ram and reinstall the intake duct without leaks.

Steps

1. Disconnect the battery and intake

   With the ignition off, disconnect the negative battery terminal. Release the air box clips, disconnect the breather hose and intake sensor, loosen the duct clamp, and remove the air box and intake duct without pulling on wiring.

2. Clean the throttle plate

   Use cleaner labeled safe for throttle bodies and apply it to a cloth or soft brush. Gently remove deposits from the throttle bore and plate edges; avoid flooding the assembly or forcing an electronic throttle plate by hand.

3. Reinstall the intake components

   Seat the air box and its seals, reconnect the intake duct, breather hose, and sensor, then tighten clamps and secure the housing. Ensure no tools or cloths remain in the intake path.

4. Reconnect power and verify idle

   Reconnect the negative battery terminal and start the engine. A brief idle change can occur while the computer relearns; check for intake leaks or warning lights and follow the service information if rough running persists.

Check your vehicle’s repair manual for exact specifications and fit.
