It would be very hard. you may need a professional to do that.

it is in line with your exhaust system. it is a piece of metal just like a muffler but a little bit smaller and it is located between the engine and the muffler. you will need to cut that piece and weld back a new one on your exhaust pipes which would require you to use acetyline torches.

be carefull if you would DIY.

tnx 4 using fixya.

before you go changing out the catalytic converter realize that the engine light comes on with only a few percent of the catalytic converter plugged - so before you change it, clan out the engine combustion chamber. i did this on my ford Taurus and with a $5 can of carb cleaner, it solved the problem

How do you know if your cat converter is going bad? Can you test for it?


There are two ways a converter can fail:
  • It can become clogged.
  • It can become poisoned.
There really is no "inspection port" for the consumer or mechanic to see an actual clog in a converter. Often, the only way to tell if a catalytic converter is malfunctioning (plugged) is to remove it and check the change in engine performance. When a clogged converter is suspected, some mechanics temporarily remove the O2 sensor from the exhaust pipe ahead of the catalytic converter and look for a change in performance.
A catalytic converter relies on receiving the proper mix of exhaust gases at the proper temperature. Any additives or malfunctions that cause the mixture or the temperature of the exhaust gases to change reduce the effectiveness and life of the catalytic converter. Leaded gasoline and the over-use of certain fuel additives can shorten the life of a catalytic converter.
A catalytic converter can also fail because of:
  • Bad exhaust valves on the engine
  • Fouled plugs causing unburned fuel to overheat the converter
­Sometimes you can tell that a converter is clogged because you don't go any faster when you push the gas pedal. Also, there usually is a noticeable drop in gas mileage associated with a clogged catalytic converter. A partially clogged converter often acts like an engine governor, limiting the actual RPMs to a fast idle. A totally clogged converter causes the engine to quit after a few minutes because of all the increased exhaust back pressure.
The catalytic converter, like the rest of the emissions system, typically has a warranty length that exceeds the term of the warranty for the rest of a typical U.S. automobile.
Here is a safety reminder: Do not park your car over tall grass or piles of dry leaves. Your car's perfectly running catalytic converter gets very hot -- enough to start fires! You can keep it running well by keeping the ignition system in top shape, to prevent any unburnt fuel from entering the catalytic converter.

How do I repair obd code p0430 bank 2?


P0430 means that the O2 sensor behind the catalytic converter is detecting that the catalytic converter is not functioning properly. This can be caused by a bad sensor, and exhaust leak or the actual catalytic converter is bad. Check for leaks 1st. The sensor is changed by unhooking and unscrewing it from the exhaust pipe, the catalytic will need to go to a repair shop. Hope this helps, let me know.

Camshaft sensor and catalytic converter


Sometimes one problem causes many more. The camshaft sensor should be easy to access. Go to a good parts store and have a look at the diagram for part location. You may not need a Catalytic converter yet.

If the camshaft sensor went crazy you will not fire on all cylinders. Therefore the exhaust mixture will be rich and can damage the Catalytic converter. But when the repairs are made to the Camshaft sensor, give it some time to run correctly and see if the Catalytic converter clears up.

As with any repair, disconnect the NEG battery cable for 10 minutes to clear the old codes. Then use the car and let the car go for 300 miles or so to purge the Catalytic converter of excess fumes. Then if you need a newer Catalytic converter its almost like installing a muffler. You may need a special socket to change out O2 sensors from old to new.

Costs vary, Sensors are $20 to $50. Catalytics can be expensive, but Salvage yards have them used.

Catalytic converter


The short answer is NO... It's not like changing a muffler in the "good old days". They are welded in and need to be cut out then rewelded, etc... not an easy job unless you have access to shop tools.
Can I ask WHY you need to change the converter??? They usually last as long as the car. I recntly sold a 1998 Olds with 245,000 miles on it and it had the original converter intact.
Good Luck

Not just a faulty catalytic converter will trigger this code. Many other issues can trigger this code.

  • Leaded fuel was used where unleaded was called for
  • An oxygen sensor is not reading (functioning) properly
  • The engine coolant temperature sensor is not working properly
  • Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
  • Delayed spark timing
  • The oxygen sensors in front and behind the converter are reporting too similar of readings
Possible solutions:
  • Check for exhaust leaks at the manifold, pipes, catalytic converter.
  • Replace Coolant Temperature Sensor
  • Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
  • Inspect the downstream heated oxygen sensor (HO2)
  • Replace the catalytic converter
  • Have timing adjusted
