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.

check engine light on, cruise flashing, another PO131 code on my 2005 Subaru
the check engine light is on and it hesitates,i need to take my foot off gas and lowly climb speed,and while stopped at light etc it struggles to remain at a steady idle and often will stall, ive replaced both sensors twice, i have owned 3 subarus and if this prob isnt fixed a new wrx is NOT in the near future as planned where do i go for this problem, i just need the sensor i can install
Check engine light on and cruse flashing. Code indicates O2 sensor.
My Check engine light came on so I took it to a mechanic. They ran a diagnostic test on my Subaru and it reported that there was an issue with the O2 Bank 1 Sensor 1. I have not yet fixed it as I am researching the best way to take care of the problem (this is how I found the recall).
Check engine light - Oxygen Sensor
This is the second time I have had to replace the oxygen sensor. First time was at 65,000. I bought my 2002 Subaru Forester new and maintained all the required maintenance needed to keep it in excellent condition.
check eng light, sensor fault code for front sensor.
P0032 check engine light code
Spent $110 for a diagnosis, but have not fixed the problem.
Check engine came on code P1153 Upstream air/oxygen sensor
The engine warning light came on unexpectedly while driving including the cruise light and kept blinking. I brought it to the dealer where I had purchased the car Don's Ford Subaru and they said it was the oxigen sensor at fault. They replaced it and the total cost with tax came out to $480.89. I had asked why this happened with such low miles and they said when a car gets older this can happen and that this vehicle has two sensors and the other one is ok.
Check engine stays on, OBD2 says o2 sensor & Idle control valve. replaced both, problem remains. Car surges, has trouble maintaining steady idle.
I have front O2 sensor (Sensor # 1) failing and check eng. light. Diagnostic shows the #1 O2 Sensor failing. Problem has not yet been fixed. It is a 2004 Subaru Forester X2.5
Cruise control light blinks and check engine light stays on, had sensor reset and turned off cruise control was good for few days and happened again. Car is running fine, shop said new catalitic coverter is $850, just want to be sure it needs this and not a new sensor.
Bad front o2 sensor... Bought new one, jacked up car and fixed myself
Check engine light came on. Took the car to be checked. Mechanic said sensor was not functioning an had to be replaced. It was fixed for $351: $210 for the sensor and $141 for labor.
Bought the car from a dealer who obviously reset the light because it came on within 60 miles of ownership, so the mileage above probably isnt the most accurate.
Check eng light is on, code is for O2 sensor B1 S1
2002 Subaru Forester. O2 sensor causing check engine light to come on. Now could be linked to transmission lag-?
took it to the dealer. it went away for a few months and been back since.
