Today I pulled the code P2270 after my SES light came on. The information i gathered shows that the code indicates that the Bank 1 Sensor 2 was sticking in the lean position. Can anyone on this forum let me know which side of the engiine is referred to as Bank 1? Is Bank 1 on the passenger side of the engine compartment or is Bank 1 on the driver side?
