How to Locate a Dodge Ram OBD Plug

by Jeffrey Caldwell

Dodge Ram pickups built after 1996 are equipped with a system of sensors known as on board diagnostics (OBD II) which monitors the function of vital emissions components and relays that data back to the engine control module. When one of these components or sensors fails it sends a trouble signal to the engine computer, which in turn illuminates the “check engine light” located in the dash. An OBD scanner is required to read the data stored in the computer, so you can know which component has failed. This scanner usually connects to a diagnostic port located in the passenger cabin. The location of this port varies from vehicle to vehicle.

1996 to 2001 Vehicles

1

Park the vehicle on a level surface.

2

Press down on the parking brake pedal to set the brake.

3

Feel with your hand along the bottom of the dash, on the driver's side of the vehicle. The plug will be located just above the gas pedal.

2002 to 2008 Vehicles

1

Park the vehicle on a level surface.

2

Press down on the parking brake pedal to set the brake.

3

4
