The CEL light is on on a JDM STi7, and when I connected my DeltaDash unit to the car I am getting this fault code:

P0031:HO2S Heater Control Circuit Low (Bank 1 Sensor 1)

Can anyone out there tell me what the above fault refers to. I would be very gratefull.

Thanks in advance

 

Lamda sensor heater??

Thanks David,

Does your questionmark mean that you are not 100% sure?

I am not sure if you are correct because :

P0032:HO2S equates to Heater Control Circuit High(Bank1 Sensor 1)

Does any one have any ideas on this P0031 code?

 

David, sorry for questioning you on the above topic.

I did some research and came up with this:

P0031 Front oxygen (A/F) sensor heater circuit low input.

and it came from this site: http://www.troublecodes.net/Subaru/

Thanks again for the help!!!!
