Hello all, my Check Engine light came on yesterday. I went by Advance Auto for there free scan. It came up with a P0134 O2 Sensor code ( Bank 1 Sensor 1). Ok so I know that it is the sensor but since I've never replaced one of these can anyone tell me which one this is. I know that there are 4 of them front and back but I don't know with the code above if it is the back ones or front. Is there a drawing anywhere out there as to show me exactly where they are. Thanks for your help. Looking to buy the part today. 10-06-05

OK the sensors are located in the exhaust pipes. You have one in the manifold and one just after the catalytic convertor.

Bank 1 is the left (passenger side) as you look at the engine, so sensor 1 is the first one in the manifold. :)

well on the 99 and up the O2 sensors are differnt on the front then on the back. so the two front ones are the same and the two backs ones are are the same but they are different from the front ones

Thanks guys...I'll be buying my 02 sensors from RockAuto today. I will replace them on Sunday. How long could you have gone without changing them and what problems could have happened. Thanks

If you order from rockauto and let me know when you get them because their website says a 25 business day shipping period. I need one also but don't want to wait 5 weeks.

Well let me know if you got them and if so, when did you order them so I'll order mine from there. Advance Auto is $109 but I'll have to wait around 10 days for delivery.

I ordered the sensors on Monday. Got them today. These are just like the bosch ones but different brand. I might be wrong but I think the ones from Advance Auto you don't get them with the connector in tact. You have to put it together. Could be wrong though. Here is a code that you can use to get 9 bucks off. I got it through an email from them. Hope it works for you.
Enter the discount code 280308230504 (and no other characters or spaces) in the "How did you hear about us" line of the shopping cart.
