P0420 is a cat code. Sometimes, you can replace the upstream & downstream air/fuel & O2 sensors, run some good fuel injection cleaner thru it, and that might fix the problem. If not, you may need to replace the cat. Note that the cat is covered under warranty for 8 yrs/80,000 miles. Toyota will replace it if it has gone bad, for free.

SOURCE: have had two catalytic converters go out in last 8 months

Catalytic converters should last the life of the vehicle. usually they are damaged be a poorly running engine. most common causes are lean misfire causing unburnt fuel and air to get into the convert and ignite there. coolant or oil burning. engine running too hot (lean) overheating converters.

was it the same converter that went twice? did they change them at the same time? where the pre-converters? is the engine light on?

Toyota camry problems

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

1987 Toyota Camry. Idle doesn't drop. Stays very high. No clue why. Also goes through a lot of gas and found out muffler and catalytic converter aren't hooked up. Ideas of where to start?

check your vacume hoses and if iyt has an idle controll valve that is off of the air intake. that should be the only things that would effect it

Intermittant P0136

OK Thad code PO136 is your oxygen sensor the one before the catalytic converter and yes if your you bought your car brand new
from the dealer ship yes you are covered by the factory warranty
but if you got it from a used car dealer then you are not.

If you are not covered the good news is than that is not so hard to change.
all you need is a jack a oxygen sensor tool ( you can get it as a loaner on Auto Zone no charge ) and a new oxygen sensor.

If you don't know how a catalytic converter looks like click this link
good luck.

As long as the area you live in doesn't require emission testing, you don' need to fix it. It won't hurt anything. But you will have to stare at the light or put tape over it.

Catalytic converters

If you are going to change the convertors I would just replace the first one closest to the engine. But when a computer code says "bank" they usually are refuring to the Oxygen sensor that is there , they are classified as bank 1 and bank 2. 1 being closest to the engine and 2 being farther down the exhaust. If its a computer code that told you bank 1 you might need to look at your oxygen sensor instead of your catalitic converter.

Toyota camry 2001emission not ready (Readiness == Fail )

The P0420 code, usually associated with a weak cat converter, is in fact often caused by an ageing (weak) downstream O2 sensor. On both my cars at around 150K miles replacing the downstream O2 sensor was all that was needed to clear the code. No cat replacement was necessary. If one actually spends some time reading the diagnostics procedure for this code, they will find that the O2 sensor diagnostic is the first thing to do before replacing the cat converter. The downstream sensor, the one after the cat converter, gets "lazy" with age. This means that it no longer produces voltage signals as it used to. The result is that the voltage swings that come out of it begins to follow very closely the voltage that is generated by the upstream O2 sensor. When this happens, the car computer thinks the cat converter does not do its job (which might as well be the case too, but the O2 sensor is the first thing to try). With a code scanner with live data stream you can see the voltages coming from the O2 sensors. Check-out my write-up on the 2002 Toyota Prius cat converter replacement on
- I got some details there. And see my comment for Dennis above here too
