Dodge Caravan Purge Solenoid Wiring Diagram: Everything You Need to Know

If you own a Dodge Caravan, then you know how important it is to keep it running smoothly. One of the most common issues that Caravan owners face is with the purge solenoid. In this article, we will discuss everything you need to know about the Dodge Caravan purge solenoid wiring diagram. We will cover the basics of the purge solenoid, the wiring diagram, and some frequently asked questions.

What is a Purge Solenoid?

A purge solenoid is an important part of your car’s evaporative emissions system. This system is designed to control the release of fuel vapors into the atmosphere. The purge solenoid works by controlling the flow of fuel vapor from the charcoal canister to the engine. When the engine is running, the purge solenoid opens to allow the fuel vapor to be burned in the engine. When the engine is not running, the purge solenoid closes to prevent fuel vapor from escaping.

The Dodge Caravan purge solenoid is located near the engine, and it is connected to the fuel vapor hoses that run from the charcoal canister to the engine. It is controlled by the engine control module (ECM) and is powered by the car’s electrical system.
