Hey Guys,

I have a 2009 WRX-S (39K miles) and its thrown up the P0031 Code. This points to being the Front Air/Fuel sensor. I have cleared it using an OBD adapter and it keeps popping up (not immediately) at random times, I clear it again, etc...

Is there any reason why this would go this early? Would mapping it have an effect on its life (4K miles ago).

I have exhausted the forum looking for information on this sensor, but cannot seem to find the code for the replacement sensor (not paying £400 to get it done by Subaru). There are so many to choose from on eBay and throughout the internet!! I believe the sensor on this model is different to the STI?

Any information on the sensor or where to buy a replacement would be grateful!

Thanks

Not sure if this site will help for the codes.

Also I think importcarparts.co.uk should have stock of sensors

I understand the code that is displayed, but not sure what sensor to buy to replace it with. I emailed import car parts but they haven't gotten back to me in a couple of days.
