FAULT CODE
#2
Drifting
P1128 Oxygen Sensing Adaptation Area 2 (Cylinders 1 . 3) - Rich Threshold
Fault conditions: Fuel/air mixture is so lean that sensing has reached its rich threshold.
FauIt area:
- Intake air system leaking.
- Fuel pressure too low.
- Volume supply of fuel pump too low.
- Fuel injectors fouled.
If DTC P1128 or P1130 (oxygen sensing at rich threshold) is stored in the memory, this means that the fuel/air mixture is too lean.
Air leaks ahead of the oxygen sensors can lead to a fault in adaptation. Also, check exhaust system for leaks.
