Component Location
Bank 2 Sensor 2 EGT sensor is located downstream in the exhaust system after the catalytic converter or DPF on the side opposite cylinder one.
Manufacturer Notes
Some manufacturers use multiple EGT sensors for DPF regeneration control and may set this code during active regeneration cycles if sensor drift occurs.
