Oxygen O2 Sensors for Catalytic converter HELP

Postby tooth knockn » Sun Jun 28, 2020 12:46 pm

HI
I have a 2009 EX35, I love it.. awesome car.

It just reached 121,000 miles

New Radiator 2 years ago

NOW
SO I recently had a P0420
and STILL HAVE a P0455 and P0456 and a P0442

I changed my Left Driver and Right Passenger catalytic converter along with new exhaust piping leading to the muffler.

The P0420 is gone, now I have P0430 !!!

I now want to change all of the O2 Sensors, But I dont want to get OEM, since they are pretty expensive.

Which Aftermarket O2 Sensors are good ?

Hopefully the new sensors will fix the issue

they are, you can install defouler like this:
https://www.amazon.com/Degree-Sensor-So ... 070&sr=8-2
This will eliminate check engine light.
