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?
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?
Twice in one week check engine light on, solid, flashing cruise control and x mode warning signs
engine light on due to O2 sensor defect and replaced a new sensor at the dealer.
Check engine light on. Codes call for bad O2 sensors.
Changed front sensor twice, light again that sensor has problems
Check engine light came on couple days ago. Car is running just fine. Diagnosed as oxygen sensor problem. I have replaced the O2 sensors twice before. Is there a recall for 2003 Subaru Forester?
Car was running poorly and check engine light came on.. had subaru dealer put on computer and it came back failed o2 sensor
My 2004 Subaru Outback H6 sedan has this issue.
Car running fine. Check engine light went on. Then cruise control dash light flashed. Mechanic checked with diagnostic computer, reading said O2 sensors failed. Waiting for smoke air test to detect leaks, then repair estimate.
02 Sensor went out and was stripped from the catalytic converter. Catalytic converter and 02 sensor was replaced along with the other sensor
I had an exhaust leak on the passenger side muffler that got worse over a year or so, ending with the pipe corroding and separating from the muffler. Took the car to a shop and they welded in new pipe, both sides; fixed that problem, but then the CEL came on and will not reset. Based on this recall I will try to see if the dealer will replace the oxygen sensor, and hopefully resolve the CEL.
Light on dashboard. Went to mechanic and he wanted $600.00 to repair
check engine light on. Subaru has a recall program on it, or so I have read on this page
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
Check engine light with code P0030
Recently had the check engine and traction light come on with the brake light and cruise control lights flashing. Reading is P0420 which comes up as catalytic converter, but upon further investigation I found it is almost always the front O2 sensor.
