yes,but the most common cause for this code is running your car too low on gas (below 1\2), or low octane before you replace your catalytic converter goto your nearest parts store a get 1 bottle of octane boost and fill your car with premium gas(i know), then have someone clear the code for you. this should help your problem if not check with your dealer most cats have 8yr/80,000 warranty.
Catalyst efficiency below threshold, your catalytic converter may have failed.Catalyst efficiency below threshold, your catalytic converter may have failed.
It has to do with your cars exhaust/emissions system, more specifically, your Catalytic Converter (Catalyst). If it is 'below threshold', then it is basically worn out and needs to be replaced. The Catalytic Converter super-heats the exhaust gases to reduce emissions into the atmosphere. Take it to your local auto repair shop to have it inspected to be sure. There is usually no charge to look at it. Be prepared to spend anywhere from $250 to over $1000 to replace it, depending on what type of Converter your car has. Hope this helped
Catalytic converter. A device that use platinum as a catalyst to reduce unburned hydrocarbon emissions from your vehicles exhaust.
The location for the O2 sensor(s) are on the exhaust manifold in front(before catalyst, catalytic converter) for checking emissions from combustion chamber or behind (after catalyst) for analyzing emissions from the catalytic converter.
It means that the catalytic converter is not working properly.
The oxygen sensor(s) installed after (downstream of ) the catalytic converter(s) are called catalyst monitors
It means that the catalytic converter is not performing to specifications and should be replaced.
In plain English it means that your catalytic converter is failing.
Catalyst efficiency below threshold. (The catalytic converter may be failing.)
Pre-catalyst is a catalytic converter that is fitted to Diesel engines to control emissions soon after engine start up when the main catalytic converter is not yet up to operational temperatures. In Europe a pre-catalyst is commonly used where a Diesel Particulate filter is fitted for stage 4 and 5 emissions requirements. The DPF is placed upstream from the main catalyst and in turn prevents the main catalyst heating up quickly enough to control the very initial emissions.
Try replacing Catalytic Converter on the opposite side of cylinder 1
Catalyst efficiency below threshold (bank1) You may have a tired catalytic converter on bank 1.
