Exclamation o2 sensor questions, please respond

i have a 2001 2.5 and the ony mods i have done is the ganz flow intake and a autometer A/F meter. Now heres my problem, about a month ago my ce light came on so i made an appointment a exeter subaru they looked at it and it pulled the o2 sensor code. so they replaced it and checked every thing else and said that the car was fine. Now a month later the ce light is back on . I've done the fuel cap check and nothings wrong ther, could it be my intake causing the o2 sensor to blow or the a/f meter. I dont think it could be either of them because my ecu would learn the new air flow coming in from the intake and the a/f meter just mesures voltage. But i could be wrong , i just dont want to be a the deaalership once a month having my o2 sensor replaced. Could someone please inlighten me on what might be going on.


thank you

Front or rear O2 sensor? My header was cracked and the front O2 sensor was throwing a DTC (P0130) IIRC. Exeter fixed both . That O2 sensor has a 12 month/12,000 mile warranty on it too .

I dont think the ganzflo would do that, I had my ganzflo for more than a year and it never sent off a code, and I do too have an A/F meter and it never sent a code off, either I bet you its another 02 code, but if you didnt make a clean connection to the 02 sensor wire, on the ecu it could be making it feak out, I would check you connection, but its proably not it, dont worry, this is far as I can help without a scantool, you really dont know what the code is. try to find someone with a scan tool

It would help a lot if you could get codes pulled. It could be two
totally unrelated things. It's hard to troubleshoot without knowing
what the actual codes are.

Not likely the front, not many a/f gauges hook up to the front on a my00-01 RS...

No, I think North Ursalia was inquiring whether the original CEL code mentioned by the thread-starter was for the front A/F sensor or the rear O2 sensor.

BTW, you CAN hook up an A/F meter to the front A/F sensor. A search of the i-Club forums will show this. Of course, they never work.
