I have a 2000 Honda Civic Ex that the engine light is coming on. I took it to have the codes read and it came up CSF sensor so I replaced it but the light is still on. I have taken it to so many places and it is now not showing any codes!!! The ECU has been reset and the battery cables have been disconnected and reconnected. What could be the problem? Frustrated.....
engine light was on, checked codes it gave CSF was bad. Replaced it but the light stayed
on. The computer was reset then the ECU was reset and drove some more. Now there
are no codes showing but the cel is still on. We had the oil and filter changed, plugs and
rotor button changed. Also ramped up the rmps because it was idling low. Help! It will not
pass inspection in NC with cel on. Desperate because no one knows what to fix.
