Catalytic Converter problem

Hi guys, I'm new to the forum so hello
I have a problem with a friends 4th Gen Prelude, It's a 1994 Japanese import.

The Cat warning light is on. I've swapped the Lambda sensor for a working one but the light is still there.
What monitors the heat of the Cat?

It's this warning light.

Re: Catalytic Converter problem

I had the battery off for a few hours. Is that how you reset the ECU on Honda's?
I've never worked on one before except for servicing.

Re: Catalytic Converter problem

It's not working

Re: Catalytic Converter problem

Do the Jap imports only have one O2 sensor in the full exhaust system?

Re: Catalytic Converter problem

they might just have one im not sure if you look under the car you should be able to see them, sense its a fourth Gen i think it has one if not two, check on the exhaust
