Question about Cars & Trucks
The fuel mixture to engine is related to how the oxy sensor reads either high or low. it is really a voltage generator and works in a renge of .1 to ,9 volts.
If the fuel is rich or too lean this voltage goes out of range and reads a fault code. The injectors could be leaking causing a rich reading or ther could be a intake manifold gasket leak causing a lean mix. If you have a lpgas torch and can blow a small amount of gas unlit of course around the manifold, if there is a leak the engine will increase in revs. all the best to you

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. Then you can access the bolts that secure the mirror onto the door
