My brother has my old '01 LS and he brought it to an autozone a few weeks ago and it was throwing codes for the front o2 sensor and the MAP sensor. The Map sensor was replaced with a Honda OEM one while the o2 sensor was replaced by a generic autozone one. The mechanic he brought it to said the CEL is still going off becase the o2 sensor is not Honda OEM ... has anyone ever tried the autozone o2 sensors...do they not work properly? Could it be he didn't install it properly?

I already had him reset the ECU a couple times and the CEL comes back on almost right away (within a couple minutes), which is also weird because I always thought it takes 50 or so miles before the computer will throw a CEL again.
