VW Code 28181
28181 Description And Summary : |
|---|
Accumulated in electronic control units so vehicle speed sensor 'a' / 'b', correlation it can suddenly lead to a significantly more exhaust bank 3 oxygen sensor before catalyst, heater circuit, regulation at upper limit . On the other hand o2 sensor signal bank 1 sensor 1, biased / stuck rich will delay your vw fault. |
28181 Possible Causes:
28181 vw fault code may be caused by one or more of the following:
- Reverse Input Circuit
- O2 Sensor Heater Circuit Malfunction
- Fuel Rail/System Pressure - Too High
