I have a 2001 Impreza L wagon (basically the outback sport without the trim package). Two weeks ago I start the car and check engine light comes on. Code is 1130 - front oxygen sensor circuit malfunction. Subaru dealership checks it and confirms oxygen sensor is bad. They don't have the part in stock even though I told them before bringing it in that was the code. After paying the diagnosis fee I take it to a reputable independent repair shop and they again run through the trouble shooting checklist and confirm the sensor is bad. They replace the sensor, which they said it pretty much came out in pieces, with a new bosch replacement sensor. After resetting the check engine light continues to come on with the same p1130 fault code. They say that the problem is the computer that processes the sensor data and that I have to take it to Subaru to get that fixed. Does anyone have any suggestions where to go from here? Is it possible to confirm the oxygen sensor is in fact working? Is there another way to reset the computer or should I just take it to Subaru again?
