1997 Toyota Corolla 4 cyl Front Wheel Drive Automatic 180000 miles
My check engine light came on, so I took it to Auto Discount to get it decoded. I got 3 errors. Two of them were the same:
1 x P0133 - O2 Sensor Ckt Slow Bank 1 Sensor 1
2 x P0401 - EGR Flow Insufficient
It was suggested to me that I can just replace the oxygen sensor myself. However, I do not know where to find it in my car.
