P2022 Intake runner position sensor: signal or voltage too high (bank 2)

By: Diagno editorial team · Updated: 2026-10-15

P2022 means: Intake runner position sensor: signal or voltage too high (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 €60–300 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. The signal voltage is too high. Usually a wire is shorted to power, the ground is broken or the part itself has failed. 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

1. 1Connector loose, damp or corroded
2. 2Wire shorted to power or ground broken
3. 3Faulty actuator or sensor
4. 4Engine computer fault (rare)

Repair difficulty: Moderate

What you can check yourself

First look at the connector and wiring: anything loose, melted or green with corrosion? 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

1. We read the fault data on the diagnostic tool and check whether the fault is constant
2. We measure the circuit's supply, ground and signal
3. We repair the wire or replace the connector
4. If the wiring is fine, we replace the actuator or sensor
