04 catalytic converter issues
Hello, I have an 04 Camry SE, I4, 147,000 miles. Car was bought and registered in Texas but has Califonia emmissions. I have the p0420 code (bank 1 catalyst) and have been advised the cats regularly fails in these cars. I replaced both the front air fuel sensor and rear o2 sensor last year. Doing my homework has caused me to have some questions. If I replace the front exhaust manifold/catalytic converter with the fed unit, will the check engine light come back on? If so, can the CPU be programmed to accept fed unit. Or do I need to purchase the more expensive California spec unit? And do I need to replace the secondary cat now or just wait? Thanks.
