Hello there.

Hi, this its my first post, and sorry for my bad english.

I have a Civic 00 SI coupe stock, with the B16A2.

my problem is: sometimes the light of (check) engine is turn on, and I was take the code (DCT) and I give 2 code:

45 Fuel system too rich or lean
67 Cat Converter

later of this I reset the baterry of the car, and the light is turn off, but later when I dirve the light returno turn on.

what can be the problem.

thanks and sorry for my bad english,

 

Code 67 for catalyst efficiency is easy enough to fix - replace the convertor with a properly working convertor

Code 45?

That code is much harder to properly diagnose as it can be caused by MANY different things. You need to have an OBD2 scan tool hooked up to your car to verify if the code is for too rich or too lean. "Code 45" means too rich or lean. An OBD2 scan tool can tell you which it is.

Things that can affect too lean or too rich conditions:

Valve clearances
Fuel filter
Fuel lines
EVAP system
Exhaust leak
Primary oxygen sensor
Fuel injectors
Vacuum leak(s)
Bad gasoline

As you can see it's not the easiest code to diagnose due to the amount of things that need to be checked. Some things such as EVAP system cannot be checked at home. Other things like checking o2 sensors(s) need to be done with a multi meter.

 

first: this item of ebay can work for my car and replace the convertor:

and so thanks for help-me, I live on Honduras, and here no much people know about honda.

 

No that item replaces your convertor with a straight flow test pipe/resonator. It will still throw the code 45 for certain with the pipe installed.

 

where can buy this converter good and cheap, but I need buy this online.

thanks
