Seems like when they replaced my hood (before I bought it) they didn't transfer the sticker and well on a prius I don't see the number on the valve cover but then again it might be so far back you can't see it I need the efn or something. Anyways does any1 still have an 04 prius registered in California at least originally that can take a photo of that sticker. terramir
I don’t have a photo, but if you need a replacement emission control information label, why don’t you just buy one from a Toyota dealer? For model year 2004, it’s part number 11298-21100, list price $3.07, listed in catalog Figure 74-03, Caution Plate (Exterior & Interior). The information from the label, such as the test group (4TYXV01.5MC1) and evaporative family (4TYXR0030P41), can also be found in CARB Executive Order A-014-0466 (PDF) and EPA Certificate of Conformity 570T2-04 (PDF).
