I'm a little puzzled by the wording of the question. I suspect that whoever told you this didn't explain your problem right, or maybe they didn't know whta they were talking about to begin with. The reason is that you are asking about two completely unconnected and unrelated systems. There is no such thing as an "evaporative system oxygen sensor." The evaporative system and the oxygen sensors are two separate systems that have no relationship to each other and there is no DTC that relates to a combination of both under the same diagnostic failure. I suggest you start over with finding out what is wrong with your car. Which is it? The evap system? Or the oxygen sensors? Somebody needs to properly diagnose your vehicle and then PROPERLY explain to you what is wrong. Assuming that this individual knows what they are talking about, they should also be able to give you a ballpark figure of what it will take dollarwise to get it fixed.
A vehicles evaporative emissions system consists of multiple components such as the vapor canister and purge filter. In order to repair evaporative problems the failed/failing components must be diagnosed and condition verified. A common method is scan for OBD trouble codes, and inspect hoses for leaks.
Driving with a bad evaporative canister can lead to issues such as reduced fuel efficiency, increased emissions, and potential engine performance problems. While you may be able to drive for a short period, it's advisable to address the issue promptly to avoid further damage to the vehicle's emissions system. Ignoring the problem can also lead to failed emissions tests and costly repairs down the line. It's best to consult a mechanic for a proper diagnosis and repair.
P0455 requires two failures in a row to turn the light on. Pending means that it has failed the large leak test once. Treat it like an active code. P0455 evaporative emissions large leak.
The leak detection pump (LDP) in a Mazda 3 is part of the evaporative emissions control system, designed to detect leaks in the fuel system and ensure compliance with emissions regulations. While the vehicle may still operate without it, the absence of a functioning LDP can trigger warning lights, affect emissions performance, and potentially lead to failed inspections. Therefore, while not essential for basic operation, the LDP is important for maintaining the vehicle's emissions system and overall performance.

Here's a few suspects:# Switch has failed # Fuse failed # Motor under the seat has failed # Wiring to the seat is broken See "Related Questions" below
The catalytic converter is most probably broken
The car failed because it has a problem The problem will require repair There are literally a thousand possible problems, each with a special repair needed.
If an 02 sensor has failed, it can only be replaced. See "Related Questions" below for more
What about it? All cars will produced NOx. If it failed a e-test it will be because either the catalytic converter is done or the EGR is not working. Or if you have a VR6 then it could be a the secondary air pump not working.
For a Windstar, a common problem is a failed temperature blend door motor - actuator. See "Related Questions" below
In most cases the fuel gauge sending unit in the fuel tank has failed.
