Irishbrian Posted June 2, 2014 Share Posted June 2, 2014 Hi, I have changed the lambda sensor on my subaru impreza wrx 2006 bugeye after reading fault code which said "bank one" was the one to change. I purchased a universal one on eBay and I have cleared the fault so it reads no faults but engine management light is still on. Any ideas?

Crazyeights Posted June 2, 2014 Share Posted June 2, 2014 (edited) Hi, I have changed the lambda sensor on my subaru impreza wrx 2006 bugeye after reading fault code which said "bank one" was the one to change. I purchased a universal one on eBay and I have cleared the fault so it reads no faults but engine management light is still on. Any ideas? Thanks Brian ^^^^^^^^^^^^^^^^^^^^^^ Here a possible clue to the problem. Is it wired EXACTLY right? Why wasn't a direct fit unit selected instead? Is it the same code as before?

Irishbrian Posted June 2, 2014 Author Share Posted June 2, 2014 I believe so the colours were different but I found a link which said, Current sensor. Blue - signal to ECU, white - ground, black x2 - heater. Universal sensor. White x2 - heater, grey - ground, black - signal to ECU. So, blue to black, white to grey, black to white, black to white. Any thoughts? Thanks Brian Link to comment Share on other sites More sharing options...
Irishbrian Posted June 2, 2014 Author Share Posted June 2, 2014 And the subaru sensor is £150 trade and the universal is £32. It's not reading a code at all now it cleared it ok but engine management light is still on. Link to comment Share on other sites More sharing options...
Olnick Posted June 2, 2014 Share Posted June 2, 2014 If the CEL (Check Engine Light) is still on the car's computer must think there's still a problem--maybe something other than the O2 sensor. Did you check for codes again after you installed the new sensor? What brand sensor did you use? How did you connect the wires--solder? Crimp? Some kind of "connector box" provided by the manufacturer? Does the car seem to be running better (or at least okay!) with the new sensor installed?

Irishbrian Posted June 2, 2014 Author Share Posted June 2, 2014 Hi Olnick, Yes. I plugged it in and cleared the code. Tried it several times after and it was reading no errors. The make is ZIRCONIA I believe, a connector box was used. Car is running fine haven't noticed any change. Is there any other way to clear it? E.g turning eginition on and pushing the brake? I've just heard of weird ways of doing things like resetting service light etc. Thanks Brian Link to comment Share on other sites More sharing options...
Olnick Posted June 2, 2014 Share Posted June 2, 2014 Sorry Brian, I don't know of any secret handshakes. You might try disconnecting the battery for an hour or two, see what happens. Hopefully someone else will chime in with ideas. Good luck. 1 Link to comment Share on other sites More sharing options...
