P2022 sets when the bank 2 flap position input reads close to the supply voltage. Ford's limit is above 4.7 V for 5 s on its V engines with vacuum-operated runners (shown from 2024 as P2019 with failure byte 15); for the Touareg hybrid engine CGFA (2014) Volkswagen gives more than 4.88 V. Such a value is rarely real travel – it normally means the sensor ground or signal line is open so the input floats up, or the signal wire has contacted a 5 V or battery feed. Wiggling the harness while watching the live value helps to tell a broken wire from a failed sensor. With P2017 on bank 1 at the same time, check the common ground first. The flaps are usually left unpowered, so the engine runs on with slightly less low-speed torque.

Likely causes

Bank 2 sensor ground or signal open
Signal wire touching a 5 V or battery feed
Bank 2 position sensor open internally

Symptoms

  • Check engine lamp on
  • Little or no change in drivability
