I got a Check Engine Light on my NA '99 V70 (125k miles)the other day. I had it read at AutoZone. The code was P0130, the front O2 sensor. I had a code about 6 months ago and cleared it. I think it was the same code. I cleared this one yesterday, but it came back today.
I've searched this code and found a few posts about people replacing the O2 sensor only to have the code return. It seems our cars sometimes throw false codes. Some owners have had to replace both sensors. And some others have had to use the Denso sensors. Ouch!
What's the latest advice on this code. Can I check the sensors? Are the Bosch OE and universals as good as the Densos? Do I have to go to the dealer for this fix? I'd sure hate to buy one or more sensors to have the code return. Any suggestions? All help is appreciated.
