Answer - Fuel Injection & Emissions SysThis refers to the fuel injector and emissions system. For the 2002 model, see your book that came with the car, page 2-56, in the "gages" section. Some auto parts shops offer free use of a computer diagnostic device, that plugs into the computer under the dash (a white jack on the 2002). Just plug it in, carefully, like when installing items into the back of your computer. Aim to to match which side it is facing, in other words. It'll then tell you codes, which include for emissions, the PO446 you cite, and PO440 and PO441, for example.

Just because you read a code does Not mean that is what is wrong. There are diagnostic steps to take so you do not replace unessary parts. The problem can be as simple as a cracked vacuum hose.jd

Ive had the same code and code PO441 both PO441 and PO446 are only regarding the emissions system not the fuel injectors! mine was the purge solinoid light went out then came back on 4wks later there are a number of things it could be but from things ive read about this is other Chevy prizm owners have had the same constant problems. take it in and have a smoke test done. good luck!!
