Check Engine Light Due to Failed Front O2 Sensor on Subaru Outback

Problem Description and Possible Solution

The front oxygen (air fuel ratio) sensor element may develop a crack, causing the Check Engine Light to illuminate. Subaru has recalled certain models to replace sensors that may fail. The Subaru service program number is WXW-80, this is not a government mandated recall.

Yesterday I changed all four disc brakes will new slotted disks and ceramic pads. The check engine light, anti skid off light are on and the cruise light flashes. I ran the code and got P1155, reset and it repeated. Could the o2 sensor been disturbed when I jacked up the car?
engine light on due to O2 sensor defect and replaced a new sensor at the dealer.
Twice in one week check engine light on, solid, flashing cruise control and x mode warning signs
Changed front sensor twice, light again that sensor has problems
Check engine light on. Codes call for bad O2 sensors.
Light on dashboard. Went to mechanic and he wanted $600.00 to repair
02 Sensor went out and was stripped from the catalytic converter. Catalytic converter and 02 sensor was replaced along with the other sensor
My 2004 Subaru Outback H6 sedan has this issue.
check engine light on. Subaru has a recall program on it, or so I have read on this page
Just had fuel pump replaced and now the check engine light is on. went to AutoZone and they coded it as a Back Stream oxygen center but a friend told me that my car, an H6.0 outback has 2 up front and 2 in the back...do I need to have them all replaced?
irregular idle, rotten smell in area of sensor, codes read. not yet fixed,am calling local dealer (suburban Subaru) tomorrow.
Cost 415.00 at dealer to fix
