P2022 — Intake manifold runner position sensor signal too high

The code indicates a problem with the sensor that monitors the position of the intake manifold runner on bank 2. This sensor helps control airflow for better engine performance and efficiency. A high circuit reading means the sensor signal is stronger than expected, often due to wiring issues, a faulty sensor, or a stuck runner.

Common causes

The cause is almost always one of a few things. Here they are — P2022 rarely comes from anything outside this list:

• Faulty intake manifold runner position sensor
• Damaged or corroded wiring/connectors in sensor circuit
• Stuck or broken intake manifold runner valve
• ECU malfunction or software glitch

Where to start

In the order a sensible mechanic would work — the cheap checks first, the expensive replacements only after:

1. Inspect and repair wiring and connectors
2. Clean or lubricate intake manifold runner valves
3. Replace faulty intake manifold runner position sensor
4. Check and update ECU software if needed

That is what holds for P2022 in general. From here it depends on your engine — tell me which car it is and what it does, and I will give you the steps for it: real procedures, torque figures and diagrams instead of general advice.
