I am showing engine codes; PO 446 Evaporative Emission System Vent Control Circuit, PO 133 O2 Circuit Slow( Bank 1, Sensor 1)& PO 410 Secondary Air Injection System. I was able to read about the code PO 133, it states upstream oxygen sensor response slower than minimum required switching frequency. I know 1 oxygen sensor is located on the manifold, is there any more & where are they located ? Any help with these faults is greatly appreciated.
