Check for water in the fuel as the alcohol in the ethanol gas attracts moisture and after setting it may have drawn too much water into the system .

Well, code 420 means the computer does not think the cat is working to spec. The computer compares data from each O2 sensor - the rear sensor should be staying on the lean side or switching very slowly, while the front sensor switches back and forth between rich and lean several times per minute. If the cat is not working both sensors would read close to the same. So if you replaced both sensors, and you still get code 420, the cat may be blown out. A mechanic would use a scanner to watch the data stream from each sensor, and measure the surface temp of the cat.

Usually an O2 sensor code is a result of another problem. Your problem is coming from the motor & the sensors are just reading it. Bad wires,coils, plus, vacuum leaks even low coolant or running hot will give you O2 sensor codes. Sounds likes you should start on wires themselves. Is it running rough? Missing? Check the plug wires & coils first. Disconnect the batt to clear the codes & take it from there. Good Luck

This code indicates the downstream o2 sensor has failed. Make sure there are no exhaust leaks near the sensor causing false readings. If the connector/wiring is ok replace the sensor

if it says o2 sensor then it must be the bumper

Hi do check the heater control valve and blower control module possible malfunction or faulty, Valve normally situated in engine bay . module will be found on internal heater box .

usually in the fusebox if this does not sort it most radios have a fuse on the rear of them inside a small cover or just plugged in
