Greetings!

I have a code P0410 on my Vantage which keeps me from passing emissions. (I also get the emission warning message and the CEL on the dash) I also get a "Pending" code P0133 for the 02 sensor "Oxygen Sensor Cicuit Slow Respnise Bank 1 Sensor 1." I'll probably have to replace that sensor as a precaution.

I checked the fuses with a meter and they're good. My next step is to tackle the pump itself. My questions:

1. How difficult is it to test the pump, and how to do so?
2. Is there any other item I need to check beside the pump?
3. Is there a chart labeling the sensor and bank for the 02 sensors?

Thanks for the input!
Marc S.

If it is the pump, solenoid for the diverter valves or valves, it's a intake plenum removal that's kind of involved. By the jump start positive connection is the pump relay. Jump the relay to check operation.

 

Thanks! I've pulled the relay. Now trying out how to jump it.
