The future is here! If you are looking to see all of your engine parameters in one little package, look no further.  This AEM digital gauge not only reads your engine parameters, but can read & clear check engine lights, right through your OBD2 port.  If you are not a big wiring guy, this is your perfect solution.  This 52mm gauge plugs directly into your OBD2 port so you'll be up and running in no time.

All automotive manufacturers were required to implement the ISO 15765 CAN bus protocol for OBDII, so this product will work with all vehicles 2008-up. This protocol was used on certain vehicles prior to 2008, however, so with a little research and inspection of your vehicle's OBDII port, you may be able to determine whether this gauge will work on your vehicle.

Determining Whether Your Pre-2008 Vehicle Uses OBDII CAN bus

If you are interested in our OBDII CAN products for use on pre-2008 vehicles that are listed in this document, and are unsure of the compatibility, one way to verify whether your vehicle is compatible is to check Pin 6 and Pin 14 on your OBDII port to confirm that it is populated with terminals.

The OBDII port pinout is defined by the OBDII standard, and Pins 6/14 are specifically dedicated to OBDII CAN Hi and Lo. If these pins are populated, it is somewhat safe to assume your vehicle is supported, since these Pins are required to interface with a standard OBDII scanner.

On vehicles with manufacturer-specific CAN but not OBDII CAN, like some 2000-2007 European vehicles, they are forced to use the “Vendor Option” pins for communication with manufacturer-specific diagnostics equipment and Pins 6/14 are left unpopulated.
