Verify connector style, terminal count, and sensor body diameter before installation.

Confirm vehicle year, model, and engine configuration against the fitment list, especially on Mercedes-Benz E320, ML320, ML430, and E430 applications with notes in the fitment data. The part number 4D-1056 should be matched to the original sensor before replacement.
