Thread: Oxygen Sensor fault code P0056 Bank 2 Sens 2.

Hi Fellas,

Fault code P0056 Heater Control Circuit Bank 2 Sensor 2.
Drivers side or Passengers side?
The bloody W/S Manual is no help at all.
I am assuming that I need to change the Driver's Side / Post Cat or downstream Lambda sensor??

A whole new world of technology as my P38 didn't have any O2 sensors.
This 2002 4.4litre has four of the rotten things.
Any advice guys?

Happy days,
Shirley.

To figure it out simply apply Bank 1 on the same side as Cylinder 1.
Bank 2 is on the opposite side and NOT in the Glove Box but I did find a dollar coin.....
