P2020 Intake runner position sensor: reading or operation not right (bank 2)
P2020 means: Intake runner position sensor: reading or operation not right (bank 2). The intake manifold has swirl or runner flaps that help the engine breathe better at different revs. Drive gently and have the car checked soon. The repair usually costs about €80–700 in Estonia.
What it means
The intake manifold has swirl or runner flaps that help the engine breathe better at different revs. The computer found that the flaps don't move correctly or their sensor is faulty. There is a signal, but the reading or operation isn't plausible. The cause may be the part itself or a real mechanical fault. Bank 2 is the side of a V engine without cylinder 1.
What you may notice
- Engine light on
- Less power at certain revs
- Idle may be uneven
What could be wrong
- 1Flaps stuck with carbon
- 2Broken flap actuator or linkage
- 3Vacuum hose or solenoid
- 4Position sensor or wiring
Repair difficulty: Moderate
What you can check yourself
On some engines a flap can break off and fall into the engine, so don't put this off for long. Best left to a workshop. It needs a diagnostic tool and experience.
How we fix it
- We check flap movement with the diagnostic tool
- We check the actuator, hoses and wiring
- We clean the manifold or replace the actuator or manifold
