Why does a 2004 Hyundai Santa Fe have two catalytic converters?
My Santa Fe’s check engine light will not go off! After having my mechanic replace the catalytic converter, the light came back on. I took it to another (recommended) mechanic and now he tells me there are two converters on my car, and that my other mechanic probably replaced the wrong one! Arrrrggggh! I just want my light off so I can pass emissions test. One more thing…both O2 sensors, the exhaust manifold, and a vacuum leak have all been found/fixed on this car in addition to the converter, still the check engine light is on!
