Hi
I had a CEL light on the other day when I did a scan it came up with
P0136 Oxygen Sensor Circuit Malfunction (Bank 1 Sensor 2) is this right as the car is mapped and de catted so dont understand why this is coming up as if the car has been mapped this error message should not show up as I belive when its been mapped it tells the ECU to forget this sensor
help would be appreciated
Stu
