Double primary O2 failure, twice within 2 weeks.

[AlexHurley]

Using my rosstech cable, I got these codes (abbreviated):

16534- B2, S1, malfunction in circuit
16514- B1, S1, malfunction in circuit

I replaced both sensors with 2 of these: http://www.ebay.com/itm/172162926121...%3AMEBIDX%3AIT

Are these not real OEM? It seemed like they are.

Now, less than 2 weeks later, I'm getting the same two codes again.

Any ideas? I'm about to warranty these buy from someone I can trust, like FCP Euro.

There's no way those are genuine for 40 bucks. Hell you cannot get universals for that price. If you're looking to save some money, I'd suggest going that route anyways.

I suggest checking your wiring maybe it fell on the manifold or downpipes

You're probably right. They even came in Bosch boxes though, I wanted to believe they were real. I already ordered 2 from FCP euro, the ebay sensors have a year warranty.
