Installation Notes and Tips

Confirm the mounting style, 2-pin connector layout, cable length, and exact sensor location before ordering. This part is listed for before-catalyst, after-catalyst, after-particulate-filter, and catalytic-converter positions depending on the vehicle. For Mercedes-Benz Sprinter 2500 and Sprinter 3500 diesel applications, verify the location note in the fitment data to match the correct exhaust position.

Use the vehicle identification number, engine configuration, and emissions system layout to confirm the correct application before installation. The part number 014494011 should be matched to the original sensor location and connector style for proper fitment.
