I mod F I then I run into problems
Well where to start I have just purchased a 07 spec B and here we go modified and there's always an issue. I have EL header Invidia DP and some straight piped exhaust. Had it tuned and all that running Danny. Just starting popin CEL codes. My first code P0171 vaccum boost leak fixed. Now P0031. Oxygen sensor. I swear as soon as you replace that factory BS with aftermarket parts no matter what or how expensive your transportation is you will always run into something acting up. Any ways is my Oxgyen sensor fried? It looks to be good wires and everything looking good.

Well... the car is a few years old now, and stuff breaks, so fix it.

Tleast it's just a o2 sensor could be worse

Google advanced auto parts promo code order one online and pick it up at a store I got one for 82 dollars with a 40 dollars off promo code

Always happens that way. Once you mod it's a never ending game. Give up now. lol

As far as O2's go I'd highly recomend going with a factory sensor. It really can be a hit or miss in the afermarket world especially when they are half the price. I've seen customers come in claiming they replaced it twice and still getting a code. After pulling the code and reading the data they still needed a sensor. Put one in and no more issues. With that said you can get lucky and get good cheap sensors as well. You just never know if they are good or how long they will last.

I have replaced both my O2 sensors in the wagon in Aug 2011.

Runs great with the new ones.

I know one of them came from Car Quest Auto Parts. $80.00, I called from work in the morning, said they would have one by noon time. Other places wanted as much as $200 + and up to 3 weeks to get one.

Call around.

To be honest I can't remember where the other sensor came from it's been to long.

It's not likely his sensor is bad when the title of the thread is "Mod FI now problems"

Here what I got popped the P0171 code. I cleared that. Now I popped P0031. Looks to be the oxygen sensor. My wideband is reading between 15.2-16.0 during cruising. Ordered a new oxygen sensor today.

Next time you get that p0171 don't clear it. Find what's wrong and fix it. Your O2 sensor would probably still be good if you A/F ratio wasn't out of whack.

Cool thanks for the help. I have a reflashed ecu. After I replace my 02 sensor will the computer do its job and correct its self. I would assume so. Figure if the 02 doesn't work neither will the computer correctly in a sense.

SpecBlitzed 01-29-2013 09:55 AM

I have an actron code reader. In it says it had 2 codes but its the same number. Are both sensors done for.

Max Capacity 01-29-2013 10:51 AM

No both sensors will have different codes, front is bank 1 rear is bank 2.

The ECU will relearn after being reset. Drive the car...

babybluelgt 01-29-2013 10:54 AM

I'm sure one of the codes will say pending. Even though you have an active code of the same number.
