00 Trooper Failed Inspection for HO2S Problem

[00trooper]

Hello,

I have a 2000 Trooper, 3.5 LS, 4x4 with about 90K on it. I read somewhere that when these things get close to this milage, the CE automatically comes on for you to change your O2 sensor. I went through inspection anyway with the CE on just to see what the issue was and it gave me two codes, both for the HO2S (Heated Oxygen Sensor). My question is how hard of a job is it for a DIYer to get at this sensor and do the work myself? I'd appreciate any help on this.
