usually its a air injection pump for the p2441
1. Check to see if the technical service bulletin number TSB-0329-08 has been performed on the vehicle. The technical service bulletin pertains to a new air pump and valves due to possible water intrusion.
2. Check to see if the air pump can produce pressure. Run the pump and then read the pressure sensor voltage. Energize the air control valves and read the pressure sensor to see if there is a pressure change in the system.
3. Check the pump to see if water has gotten into the pump. The impellers can break if water has gotten inside.
the po456 could be as simple as a bad gas cap a smoke test would be needed to properly test the system
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
