2003 BL Legacy - P0031 CEL Code

Recommended Posts

Hi Guys

Id just like to get some opinions on what to do here. I pulled the CEL code P0031 late last week after the check engine light came on. After looking around on the internets and found that the problem is "Front oxygen (A/F) sensor heater circuit low input"

But since the light came on, its turned itself off for half a day then come back on, so ive looked at replacements, and the prices im getting back are between 340 and 495. Now either one of those are just a tad steep with a young family, so ive been looking for something better and ive found this

http://www.japanparts.com/db/partslist.php?KEYWORD=&submit.x=0&submit.y=0&dealer=&car=&middlesmall=&maker=&VOLKEY=+107-079-002

It matches the part code ive been quoted by other stores, but it is just so much cheaper, the supplier has told me its a genuine subaru part and that it will work in my model legacy. So i dont really see the problem other than the fact that it is a great deal cheaper than everyone else.

Ive always figured if its to good to be true then it usually is. Does anyone have any thoughts on this much cheaper part, or even with the problem being intermittent is it worth replacing just yet.

Any thoughts on this would be great, because i dont really feel like spending $300 if i can help it.

Thanks

Me be trollin...you need those bits clint? Think afm is back up to normalish prices :( .

Ill flick you details for the dude i know. That isnt an excessive price for a wideband sensor though...there are no universal aftermarket air/fuel sensors unfortunately only on standard narrowband 02 sensors.

If you give me the number off the sensor I can price through denso see what I can do also.

Yeah evo thats my biggest concern is that its not that part that needs to be replaced coz id get shot if it wasnt. Im just not sure how to test it and be %100 sure. Everything ive read online says that the error code needs that part replaced, but want to be doubley sure.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
