It is a Fuel and Air Metering and Auxiliary Emission Controls Trouble Code.
P0056 = HO2S Heater Control Circuit (Bank 2 Sensor 2) .
How would I be able to repair this porblem? I have checked all of the Fuses, Both, inside by the drivers door & under the hood (Drivers side) All are OK. The heater fan works ok, there is some hissing noise when I change the control for the defrost and heater, but it was doing this before this problem. Thanks in advance for all of your Help.
