How to replace a catalytic converter on a 1997 honda civic

After 14 years I think it would be reasonable to have bad catalytic converter. Is there some reason your not accepting this?

• If this is the only code you are getting, for a 2000 Honda Civic, this code indicates you need to replace the Catalytic Converter.

On the 1998 Honda Civic with the D16Y5 and D16Y7 engines, the Catalytic Converter is part of the Exhaust Manifold. If you have the D16Y8 engine, the Catalytic Converter is separate from the Exhaust Manifold, and is directly between the 1st and 2nd Oxygen Sensors.

Here is a diagram of the D16Y5 and D16Y7 Exhaust Manifold and Catalytic Converter: http://www.4shared.com/document/zvR9UsXJ/1998_Honda_Civic_D16Y5_D16Y7_C.html

that is the sensor that is behind the catalytic converter, it just measures effiicency of the cat itself-the sensor has a wire that pre-heats the sensor so that it goes 'on line' sooner, it has failed or is failing-the easiest thing to do is replace the O2 sensor, or you could ignore it until you have to go through emissions, and replace it a few days prior to inspection-but if you do that, and something else malfunctions that your check engine light would warn you about, you wouldn't know it-so it's probably just best to replace it when you can, in the near future. It will not affect at all how the car runs though.

yes. it allows ambient air to enter the exhaust stream, which throws off your oxygen sensor reading, typically causing the the car to run excessively rich. it will be harder on fuel, foul spark plugs, and loose power. i definitely recommend replacing it. however, on this model, the catalytic converter is built into the manifold making it a rather expensive unit. beware cheap after market ones, the cats fail prematurely. if you are going to get an aftermarket one, i recommend using one made by Dorman Products. have installed probably close to 50 of them and had very few problems.

One is just above the catalytic converter the 2nd is just past the cat. on down pipe.

on hondas about 100,000 miles in most cases after market cats dont work correctly, you could spend over $500

this is a catalytic converter code which may require converter replacement

if the bolts are rusted
u need a torch to burn them out
remove the bolt from the front of the cat and the rear othecat
somemodels have o2sensor on them, u have to be able to remove it before u take outthe cat or u will have ahard time
if it's universal u need to cutout the old cat
if u can't handle all of this take it to a muffler shop

That is the correct place for the converter.
