Check engine light with header
A guy a work was thinking about getting a header for his 06 Accord EX. Another guy said if you do, the check engine light will come one. Is this true?
I don't have an Accord, or a header so I don't know.
Thanks

As long as you reinstall the O2 sensor you shouldn't get a CEL. And I assume this is on a 4-cyl, since you can't get headers for the V6...

Yeah, it's a 4 cylinder. Does pretty much all aftermarket headers have a place to put the O2 sensor back?
I heard this came up because one guys said you have to "ghetto sim" it to fake the system. Not sure what that means.

Re: Check engine light with header (YipMan_Style)
The front O2 sensor (the one in the manifold) is used to fine-tune the fuel/air mixture. Without it, it runs rich; & eliminating it (simulating it) doesn't really help performance anyway.
Most headers have a fitting in the proper place to install the sensor, so why not use it?
