P2020Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2020 flags a bank 2 position signal that is electrically sound but does not fit what the flaps should be doing. On the CGFA hybrid V6 of the 2014 Touareg, Volkswagen triggers it when commanded and measured flap position are more than 40 % apart or the reported value leaves the 0–100 % window. Ford's summaries describe it as the bank 2 sensor travelling too far: the plates either miss the commanded position or the sensor reports travel beyond the normal stops, and four such events are needed. Because a sticking shaft, a broken lever or a vacuum fault looks the same to the sensor, P2020 often appears next to the stuck codes P2005 or P2007.
