Throttle Body Dodge Grand Caravan 3.3L 2008-2020 Location and Replacement

Exact Component Location

In this video, I will show you the exact and precise location of the Throttle Body assembly on a Dodge Grand Caravan equipped with the 3.3L V6 engine. There is no extra fluff or wasted footage—just a straight, direct look at the top front of the engine bay, mounted directly to the right side of the plastic intake manifold plenum, connected straight to the main air cleaner intake duct hose.

How This Video Helps Your DIY Repair

While the throttle body on the 3.3L V6 is located right at the top of the engine compartment making it highly accessible, it is surrounded by the air filter box housing, vacuum lines, and a stiff electrical wiring harness. If you remove the mounting bolts out of sequence or pull the assembly away carelessly, you can easily rip the fragile intake gasket or snap the delicate plastic locking tab on the electronic throttle control (ETC) plug. Seeing the exact tool clearance, the hidden wiring clips, and how to safely separate the unit before you start saves you from vacuum leaks, avoids broken connectors, and allows you to complete this DIY automotive repair with complete confidence.

Common Symptoms of a Failing Part

The electronic throttle body regulates the amount of air entering your engine based on your gas pedal input. When the internal butterfly valve accumulates heavy carbon sludge, or the electronic actuator gears wear out, it disrupts engine performance immediately. Common signs of a bad or dirty throttle body on this 3.3L engine include a rough, surging, or fluctuating idle, engine stalling when coming to a stop, poor or delayed throttle response when you step on the gas, a flashing red electronic throttle control (ETC) lightning bolt symbol on your dash, or an illuminated Check Engine Light (CEL) with fault codes like P2135 or P2110.

Safety First!

Working on electronic engine management components requires a careful and attentive focus on automotive safety. Always wear appropriate protective equipment, including safety glasses to guard against debris and thin mechanics’ gloves to protect your hands from sharp metal edge brackets. Make sure the vehicle is securely parked on level ground, the ignition key is removed, and the negative battery terminal is disconnected before unplugging the throttle body electrical harness to prevent any accidental short circuits or voltage spikes to the engine control computer. Let the engine cool down completely before starting.

Pro Tip: If you are simply removing the throttle body to clean out heavy carbon deposits, never force the internal butterfly valve plate open or closed with your fingers while it is plugged in! Doing so can instantly strip the delicate plastic gears inside the electronic motor housing or ruin the calibration. Always unhook the battery and electrical connector first, and use a dedicated throttle body cleaner spray with a soft tooth brush to melt away the sludge gently.
