2004 Mazada MVP 3.0 Bank 1 Sensor 1
 

Hello:
What is the easiest way to get to this sensor? I have tried from under the car and the only post that I have seen is that you have to remove the plenium which is alot of work. Is this the only option? Also suddenly my check engine light quit working when I turn the switch on. Would taking the instrument panel out checking the bulb the first option after checking the fuses? I have never ever had this happen before. Thanks Mark
