Question about 2002 Mazda Protege
What does diagnostic code PO442 entail?
PO442 is an Evaporation Emission leak. It's probably a loose gas cap. The fix would be $96.00 at our dealership, since your truck is out of warranty. You may be able to get it fixed cheaper, but you'll be charged a diagnostic fee.
