We've looked up the Motor Emissions Application Guide. The 2004 Toyota Camry, both 2.4 and 3.0 engines, were not equipped with an air injection system. We recommend visiting a smog check repair station and showing them your vehicle's failed vehicle inspection report (VIR). They will be able to diagnose the actual reason your Camry failed the smog inspection. It can't be because of a faulty air injection system since the 2004 Camry does not have one, and as far as diagnosing over-the-phone that the catalytic converter is defective, that's simply not acceptable. Before condemning the CAT, a thorough diagnosis must be conducted. The catalytic converter must be the last component which is replaced, and only after all other emission systems have been deemed to be functioning properly.
