Did you get the computer read for the fault code or codes that set off the engine check light the first time and now this time?just trying to establish why all these things were replaced.generally if a cat melts down it is caused by poor fuel burn,o2 sensors and sparkplug leads,or coils if direct fire type on the top of each sparkplug.If these arent right,the cat will overheat and smell like burning oil.But it should run unevenly or down on power if misfiring.It seems as if you hadn't finished your description....and I have oil.....leak perhaps?this shouldnt trigger light unless it is leaking onto a sensor and it would have to damage it or affect the reading of it to computer.Hope this helps or get back with some more information.

Where are the O2 sensors? I found one directly behing the spark plugs on the back.

The O2 sensor (2 on V engines) are in the exhaust system pipes before the catalytic converter, the next sensor is the efficiency monitor for the catalytic converter system it looks like a O2 sensor but performs a much different function as far as testing goes. The codes you have follow.

P0420 - Catalyst System Efficiency Below Threshold Bank 1
What does this mean? In most cases it means the catalytic converter is worn out and that is sensed by the catalyst monitor I spoke of earlier.

P0102 - Mass or Volume Air Flow Circuit Low Input
Faulty mass air flow sensor
- Dirty mass air flow sensor (located in the air intake hose to the engine from the air cleaner)
- Dirty air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks

Where is the egr valve located and the mass airflow sensor

the egr would have a tube coming from the exhaust and usually bolts to the intake, the mass airflow would be in between your air filter and the inake plenum, but the car doesnt use these sensors untel its in closed loop it wont enter closed loop untill the ect(engine coolant temperature) and the o2(oxegen sensor) heater curcuit is up to temp i would check to se if you have spark and fuel if not check for pcm codes but i would probably start with the crank sensor or pcm the crank sensor is the common

1997 camry check engine light

Start with the O2 sensor, it's the cheaper solution. If the light still comes on, then it has to be the converter. Make sure you change all the O2 sensors.

99 toyota camry has error messages p1133 & p1135. which sensors & where are they located? six cylinder engine.

These are both air fuel ratio sensors, These sensors are located in the exhaust manifolds, the front one (bank 2) is easy to get to, the one in the rear is more difficult, they require a special socket to remove and install. The O2 sensors are located behind the catalytic converter and are not the same as the A/F ratio sensors.Replacing the sensors is not what the codes are telling you.You could have a plugged air filter giving you diminished air intake. That's not a bad sensor. A mass air flow sensor could be reading bad and giving you a bad mix of fuel so that your O2 sensor reads a problem. Get it? Or the O2 sensors could be bad after all, probably not both though.

I have a 2002 toyota camry V6 and did not pass

O2 sensors are a possible cause. It has one converter, but 2 oxygen sensors...1 upstream, and 1 downstream of the converter. Which means one is very easy to get to (under the hood, on the manifold), and one is not. Usually the check engine light will come on if O2 sensors are faulty.

P0420 and P0430

The AF sensors are uupstream and the O2 down stream. The car' s computer tests them and it is saying your cats are bad. If you have a scan tool you could look at the data and see what the sensors are seeing. The Af sensors are the ones that control the fuel ratio in the car while the O2's just watch. AF's would be the one to change but there is no garuatee that the codes won't come back.

Fuel efficency

check for a split in the air intake tube. the v6 has a mass air flow sensor. if air is entering the engine without being counted by the mass air flow sensor it will cause a rich condition.
