Check Engine Light on, no other symptoms.

Came on approx 2 weeks ago briefly, was off next drive, but came on and stayed on about 1 week ago.

Full vehicle scan retrieved engine fault code:
P0471 - EGR gas pressure sensor performance.

OBD gave the description P0471 - Exhaust Pressure Sensor 'A' Circuit Range/Performance.

OBD freeze frame data did not show the specific sensor in question, but it did show the vehicle was at KOEO so the engine was not actually running - because of this my initial thoughts were this would likely be an electrical circuit issue, however, this was not the case
