Aug 22, 2008 My son's 1996 Camry, 4 cylinder, 2. 4 L had a P0420 error code which says emission problem. they recommended a catalytic converter and both oxygen sensors, which we did. Soon there after the error was back. Two mechanics took the car for a ride and they said the catalytic converter and o2 sensors were working fine.

Plugging is usually the end result of a meltdown, which occurs because the converter gets too hot. This happens because the engine is dumping unburned fuel into the exhaust. The excess fuel lights off inside the converter and sends temperatures soaring. If it gets hot enough, the ceramic substrate that carries the catalyst melts.

Now at 148K Miles I have the P0420 code back. po420 toyota camry 1996 The code P0420 is for, Catalyst system efficiency below threshold (bank 1). This means that, from what the front and rear oxygen sensors are telling the engine computer, that the catalytic converter is doing a poor job. Are the oxygen sensors indicating correctly?
