Could be an electrical part that only fails after getting really hot. Coils and ignition modules are known for this. Unfortunately, these parts cannot be tested for this heat-soak type problems, other than to see if spark quality at the plugs has degraded when failing. One other thought. A bad gas cap which is not allowing air to flow in as gas is used can cause this and that is a cheap part to replace just for grins.

bank 1 is on the left side of the engine and sensor 2 is just past the converter

Scanning tells a lot. But if your not getting an engine light. Check vacuum lines first. But if you turn the key on and don't see the light. it blew or someone took it out. Then yes, start with having the codes read.

I just replaced my driver side halogen bulb in my 2005 Mazda MPV. I took me close to two hours - though the next time will likely take less than half of that. I'm not terribly mechanically inclined.

The instructions above are technically correct - however - here's a few tips.

1) Pull of the rubber boot gently without disrupting the bulb seating. Keep the bulb and clips in place!!!
2) Observe carefully how the metal clips are situated. Putting them back is the hardest part of the job if you don't understand this. The clips will attach at 3 o'clock (hooked part) and 9 o'clock (sqaure part). You might need to remove the screw slightly at 9 o'clock with a stubby Phillips in order for the clip to catch with it. Work the hooked part UNDER the catch at 3 o'clock and it will spring up in place. Trying to force it in proper will only hurt your finger.
3) Remove the small fuse panel first to provide more working room before you begin
4) You'll see a small rectangular hole crimped into the metal of the light base. This is at 6 o'clock (bottom) as you insert the bulb back into the socket. The bulb will rest in place but is easily knock out so mind how you insert the clip.
5) Have patience. If I could do it.. so can you!

I believe its located just below the oil filter.

code p 0421 refers to warm up cat converter bank 1--efficiency below threshold ===causes ---cat converter---wiring---HO2S 2 ( heated oxygen sensor) code p 0431 refers to warm up cat conveter bank 2--efficiency below threshold === causes cat converter --- wiring---HO2S 2 as the same HO2S appears in the cause of the fault I would be inclined to change it first the HO2sS sensor is the one in the exhaust manifold or before the cat converter and 2 is in the front bank of a V engine use the special socket when removing/ replacing these sensors as an incorrect tool is the main reason for wire failures on the sensors
