My check engine light first came on about 2 weeks ago, took it in and had the codes reset and it went away. came back on this weekend and took it back in for service, was told it was the oxygen sensor so they replaced it. light came on again..was told they replaced the wrong oxygen sensor so they replaced the other one. car was fine on way to work today, light came back on during drive home. anyone have any clue whats going on here??? i guess it might be easier if i knew which code they were getting.

 

does the light come on after you fill-up? if so, you could be not tightening the gas cap enough.

Here a DIY for checking your check engine light

well, i do think i've been tightening it well. i was informed of this so when i got home tonight i did unscrew and re-tighten the gas cap to make sure. when i opened it i heard a fair amount of air pressure released? is that normal? i probably sound like an idiot but I rarely pay attention to this kind of stuff. i wish i knew exactly how to do jump the terminal explained in that link so i can find out the code myself. apparently it has to be one of the codes involving an O2 sensor

 

Take it to a parts store that will pull the codes for free. Or check your recipt and post the codes on here it will be "P____" like P1456.
Tell us exactally and we can help you out better

 

Ok just found the receipts..from the first trip the code listed is P1149 on this latest receipt it does not list a code but i guess thats the same deal

 

Honda has a service bulliten out for this problem. You need to replace your ECM (engine control module). The O2 sensors were probably ok. You current computer is setting false codes.

 

so essentially i spent $300 for the O2 sensor with labor and can now expect about $800 to replace the ECM? wonderful

 

i think this is it

I would make sure before spending the $$

 

what are the odds i can get the oxygen sensor taken out and refunded since its clearly not the problem?

moogo is correct ( service bulletin 01-031 ,,) it applies to all 98-00 accords
if code p1149 ,, replace ecm..
was this a dealership ??
get your money back. they did not fix your problem , do not get upset.....kindly talk to the store manager and mention the bulletin and why they did not follow precedures to replace the ecu,, and ask him to put the money that you spent toward the ecm,, tell him that it was their mis diagnose that cost you money you should not have spent in the first place .. if this is a reputable shop i am sure he will help you out..
if he does not want to help,, call the better business bureau in your city..
