tap on it and if it rattles ,its done
Upstream would be before the catalytic converter. Downstream would be after the catalytic converter.
replace sensor,catalytic converters smell like rotten eggs when going bad
Take it to your local salvage yard and they will offer you a salvage price for the converter.
If the converter is plugged, contaminated, damaged or rusted out, it must be replaced. Likewise, if the OBD II system is showing low catalyst efficiency, the converter must be replaced. Driveability symptoms such as a drop in fuel economy, lack of high speed power, rough idle or stalling are classic symptoms of excessive backpressure due to a plugged converter. Checking exhaust backpressure and/or intake vacuum will tell you if there's a blockage. The important point to remember is that converters don't just plug up or die for no good reason. There is usually an underlying cause which must also be diagnosed and corrected before the problem can be eliminated. Diagnosing a plugged or fouled catalytic converter is only half the fix. Replacing a bad catalytic converter will only temporarily restore things to normal because unless the underlying problem that caused the original converter to fail is identified and fixed, the replacement converter will likely suffer the same fate. Always replace the O2 sensor if the converter needs replacing. That may not be all that needs to be done. A defective spark plug or wires, or a burnt exhaust valve will also destroy the converter.
we had a 2004 ford an the torque converter was bad and what it did was not shift down in geers it would go strait from drive down to first so we repleace the converter and now it works find.4.24.11For further explanation and more symptoms of how to tell if a torque converter is bad follow this link on Ehow.com: http://www.ehow.com/how_5197449_tell-torque-converter-bad.html
Oxygen sensors go in the exhaust pipes. There should be one before the catalytic converter and one after so that the computer can tell how well the catalytic converter is working.
what sensors have you replaced?? i am assuming the oxygen sensors. i need a code number to tell you what is wrong. if its a p0420 its probabily the catalytic converter. mabye a p0141-mass air flow needs to be cleaned
YES ! as soon as the engine was started , you would notice how noisy it was The catalytic converter(s) are in the exhaust system before the muffler , and removing the catalytic convertor just leaves an open exhaust pipe - extremely loud
i think it's something like 3-5 years. if not have a look on the website u got the catalytic car from and that should tell you.
Yes, It will tell you bank 1 or 2 then sensor 1 or 2 ...Bank 1 is the exhaust pipe coming from the side of the engine with cylinder 1. Sensor 1 is before the catalytic converter, and sensor 2 is after the catalytic converter.
Loss of power, poor fuel mileage, converter gets red hot, possibly check engine light will come on.
You have poorn gas milage and when you step on the pedal your car has no power. You can tell mainly by it not having enough power
