I have

P0420 Catalyst System Efficiency Bellow Threshold Bank 1

P0441 Evaporative Emission control system incorrect purge flow.

These in reference to my O2 sensors or my catalytic converters?


I just got a new catback system so I can go ahead and get new cat's if I need to.

Is this information in the Rave manual?

 

I managed to answer my own question I think.


P0420 is the O2 sensors.

P0441 is the gas cap?

How did I do?

 

P0441 could be the gas cap. Replace it, clear the code and see if it comes back. If it does then it could be the purge control valve.

 

you did well.
i have a little lookup system

cause it is easier that way.

 

Good deal

According to the RAVE 0420 is Catalyst efficiency deteriorated - LH bank.


So is this a 02 sensor or my Left hand Catalytic converter?

Don't think it's a 02 Sensor.
