CHECK ENGINE -- P1143 and P1163
I had P1143 pulled up the other day, called for a replacement of the passenger side O2 sensor pre-cat, wiped the code and it's back with another.
P1143 - Heated Oxygen Sensor 1 Lean Shift Monitoring (Bank 1)
P1163 - Heated Oxygen Sensor 1 Lean Shift Monitoring (Bank 2)
Not sure what to do now... any help would be appreciated.
Might need MAF cleaned?
