Ok, the air pump does work but still throws the code po410 and po412. It doesnt make sense that the vehicle needs to be driven for at least 20 seconds but it does. So my question here is while the vehicle is started cold and sits in park the pump is OFF and the o2 sensor is getting loaded up, and throws a pump code?! I double checked the system, no vacuum leaks, new parts, proper signal.What gives. still cant pass emissions. Im counting on you Klaus. lol
