on my 2000 prelude SH my chech engine light always seems to come on. I have just recently changed the fuel rail and catelitic converter i pull the fuse but after 10 minutes the check engine light come back on does any one know a way to prevent it from coming on?

 

99 times out of 100 when the check engine light comes on it's an O2 sensor. Take it to Auto Zone - they do free onboard diagnostic checks, and that will tell you what it is for sure. But I'd be almost certain it's an oxygen sensor.

 

yea go to autozone and have them scan it, or just borrow the tester from them and scan it yourself. The port in the lower passanger side of the center console.

 

thanks i will try that.

 

Once again some of you guys are retarded on this site. Put a paper clip in your 2 pin diagnostic port by the obd2 port and watch your cel be flashed out right in front of your eyes !

Last time I went to autozone to pull codes when my check engine/atts light was on their pos code reader said no faults, another !

 

You use a paper clip on your car's computer and you call us retarded?

Whatever.

 

Do you even have a clue on what you're fuckin talking about. You jump the connector, the same connector you jump on obd2 h22a4 ludes to check your timing. Paperclip, wire, whatever floats your boat. You obviously have no clue on what your doing. If I have to post pics for you to understand I can do that. Once the connector is jumped the check engine flashes the code. What the hell do you think on board diagnostics means dickface. I've got around 28 grand into my all motor lude, built the motor myself, golden eagle sleeved, I think I know what I'm talking about cat!

edit** I work for Honda, I've witnessed the best mechanics at our dealership do this 1000's of times get a clue boi!

 

if you could post pictures that would really help.

 

I was just trying to give him the easiest option. Its free.

 

Totally understandable man, I just trust my ecu over autozones code readers. Why waste the trip when the cel will be flashed out before your eyes at home.
