Need Help!!!
I have a 2000 honda civic hatch and CEL is on. Its a P0420.
Everyone says to replace the CAT, but I took it to get tested and it passed. O2 sensors passed also.
I dont have any air leaks.
Ive changed spark plugs, wires, cap & rotor.
Still CEL is on.
I was gonna get the ignition coil tested...
Any help would be great.
thanks in advance

Re: Need Help!!!
The car is completely stock. Im not sure if anything has ever been replaced.
I took it to get smoged and it passed all the tests except for the malfunction indicator light test(CEL). btw i live in california.
I just got all the air leaks fixed. due to idle searching. Also cleaned the IACV.

Re: Need Help!!!
Just because an o2 sensor is bad does not mean it will fail emissions. It means you reading will be higher than normal, but it can still be within Cali's specs.

But just like anywhere else that has inspection, if a CEL (MIL) is on = automatic fail, which is what happened to the OP.
