Icon9 Emissions Help!!!!!!!!!!!!

Bought an 01 Lude H22, had to put on a catalytic converter prior to taking it in for emissions. Went in and two monitors were incomplete, o2 sensor & evap I believe. So they said drive it. Did that but before taking it back after driving I unhooked the battery to have it tested not thinking about it resetting all the monitors Anyway took it back and they said showed 5 monitors incomplete, so drive it I did 700+ miles. Took it back up still 5 monitors incomplete. disconnected the battery and pulled the ecu fuse, and drove another 380 miles. Just went today and 4 monitors incomplete:

02 sensor, catalytic converter, egr & evap system

only monitor completed was: O2 sensor heater

I am at a lose as of what to do at this point. Was thinking of finding a used ECU and swapping it out thinking the current one might have been messed with, maybe aftermarket something or tune causing the issues??????

Any suggestions would be much appreciated guys, thanks in advance..

Re: Emissions Help!!!!!!!!!!!!

Is your evap system still installed?

If you can plug in a code reader and pull any CEL's, then you're still obd2.


Is the secondary o2 sensor new/good? this is the one after the converter that tells the ecu if the converter is working properly or not.

Hate to sound stupid but wouldn't know where or what the evap system looks like, haha.

I never have had any lights on the dash, or any codes when hooked up to a code reader.

And the O2 sensor u refer to is an old one.....

Re: Emissions Help!!!!!!!!!!!!

Try a new o2 sensor.


The evap is the bottle beneath the cruise control unit - which is next to the fusebox.

Basically if you see a mess of tubes and wires there, it's still in the car. Check the condition of your gas cap seal

All Gen. Prelude Service Manuals
^^ check out the fuel and emissions chapter.
I think it's 11...
Anyway, get to know the book. If you can put the pdf on a tablet, carry it with you and study the diagrams on the screen while it's sitting on or near your engine...


^^ diagram used to ensure proper vacuum line orientation.
Before I obtained a paper copy of the manual I'd use my phone to view diagrams or find out what was what as I got to know my car. Then a 10" screen was obtained, which really helped.

Re: Emissions Help!!!!!!!!!!!!

Also don't keep pulling the fuse or disconnecting the battery. Every time you do that, the monitors all reset, so unless you replace something, no need to keep doing that.

Re: Emissions Help!!!!!!!!!!!!

Thanks for the info just logged on to check back, I will check on the above mentioned things and report back!! But my one question is will a new/used ECU do anything, or is that a waste of money and time?

Update: 01/30 - yes I do have Evap System
