oxygen sensor....
 

would a dirty oxygen sensor cause my check engine light to come on ? i am getting a fit this week... and i am trading my 98 civic in...... ive never had a problem with it... EVER now the engine light is on... what should i do??? i dont wanna sink a lot of money in it.. cause i getting rid of it in a few days, and i dont want the dealer to give me less than im already getting cause im only getting 1200 as it is.... help !

did you do something to the civic that might have gotten the O2 sensor dirty, like swap parts or something?

i think it's a possibility but unlikely since the sensor isn't normally exposed to the outside. if your CEL is on, it could be anything really.

no... its all stock. i know in the manual it says the CEL is exhaust, intake etc... thats what i gathered anyway. i was hoping it was something cheap... damn. it.

when was the last time you gassed up?? If youre gas cap is loose, it will set teh CEL on

read the CEL it will tell you exactly what is wrong

havent got gas in a 3-4 days...

Did the light come on after filling up?

I'm assuming that he doesn't have access to a CAN Data comp. I could be wrong tho. But yeah, this is the best way to see what's going on. We're all guessing right now

im guessing a shop has one ? do they usually charge alot to hook up and check it out ?

Not ALL shops will have it. I work at an automotive shop, which has been up since 1926 and we get TONS of diagnostic problems. We don't have a scan tool that can communicate with 2007 cars. (CAN Data not OBD2) If you're going to a shop, make sure they can hook up to your car. TO be totally honest, your best bet is the dealer.

ok, first off, if you're selling a 98 civic for $1200, you shouldn't have to fix ANYTHING.... i am a buyer for a used car dealer and i guarantee you could get $3000 within a day on craigslist... seriously, here's an example of what the DEALERS are paying at the dealer auctions:

These are the EXACT numbers from the WHOLESALE dealer network from Manheim auto auctions... This is for a 1998 Civic LX Sedan... These are the prices they pay for them, then they mark them up $1000 - $2000 to sell to you!!

I don't mean to sound so pessimistic, i just hate when dealers lowball like that... you should get 1200 if it is totaled with frame damage and unknown miles...

the closest one to that number sold at a dealer auction for $1500... with 225,000 miles!

thanks... the guy is a friend of mine..(so i thought) its obvious he likes his moeny better than his friend..... i figured he was doin the best he could.. i appreciate everyones help and input.

*correction *money

I believe that either Autozone or Pep boys will pull the code for you for free. If not there is a way you can jump it with a paper clip and read it from your cluster.

Check that thread out and report back to us. =)

Take it to autozone they can pull hte code and even give you a printoff of what that code means and suggestions on how to fix it.

You can get the check engine light cleared by your mechanic for $25.

yup autozone will do it for free, and tell you wats wrong with it. gl

does that work for the jazz/fit as well?? i also have the light comming up on the dash, loss of power and a cam noise when driving and pushing the car in gears (but ok when revving at standstill). thought it was some sort of sensor as well.

My CEL light came on on my 99 Civic and it was my O2 sensor- they replaced it. I think it was less than $200.

Shady I know but on OBDII it will take several trips to set the check engine light for bad O2 sensor as long as it is not the O2 heater. Make sure you have the radio code! Pull the backup fuse underhood leave out for 10 seconds. Replace code should now be cleared and CEL should be off.
You will loose radio presets and if your radio requires a code you will be required to enter it.
