Order of inspection
P2020 Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 2) Low
The P2020 code means the intake manifold runner position sensor on bank 2 sends a reading that is electrically valid but does not match what the computer expects. The main effect is that the computer cannot verify where the flaps are and may leave them in a fixed position. The engine runs, with a little less performance.
