I have a 2000 Subaru Outback (purchased it new), automatic transmission and now have 96,000 miles on it. Recently the CHECK ENGINE light comes on and stays on even though the car runs fine and is getting normal gas milage. I purchased an Equus code reader and it indicates an error code of P1133. This particular error code is not listed in the official Subaru manual for this particular year equpped with automatic transmission. It does list P1131 and P1134 codes and mentions they are associated with front and rear oxygen sensors. If anyone has any additional info on this error code P1133 I would certainly appreciate more information. You can email me direct if desired: bentonjim@aol.com
