P0420 Toyota Camry 2002

P0420 Toyota Camry 2002. The readings for the o2 sensors are at 2500 rpm o2s11 between.56 and.66v; The code technically stands for: 2.) the secondary o2 sensor is malfunctioning.

P0420 Toyota YouTube from www.youtube.com

The readings for the o2 sensors are at 2500 rpm o2s11 between.56 and.66v; The engine control module ( ecm) monitors the switching frequency ratio of heated oxygen sensors 1 (front o2 sensor) and heated oxygen sensors 2 (rear o2 sensor).

A 420 sets when the pcm sees that the post cat o2 sensor is switching at the same rate (or close to the same rate) as the front o2 sensor. It reads catalyst system efficiency below threshold (bank 1) the local toyota dealer sates the first catalytic converter to be changed out. Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out of the converter.

O2s fail by not switching or they'll be sticking which will cause another different o2 sensor code to set, but not a p0420. It's a v6, i changed both. I did test the temp before and after.

I took it to the napa store and they read the code as p0420 catalyst system efficiency below threshold (bank 1). Catalyst system efficiency below threshold your solara has at least two oxygen sensors, one before and after the catalytic converter. It reads catalyst system efficiency below threshold (bank 1) the local toyota dealer sates the first catalytic converter to be changed out.

Loose or bad gas cap for the same reasons described above, a loose or bad gas cap (that cannot hold a seal) can also cause the gas tank to lose its vacuum.
