Intake Manifold Runner Position Sensor/Switch Circuit High Bank 2
What it means
P2022 means the powertrain control module read a high (out-of-range) voltage from the intake manifold runner position sensor on bank 2. That sensor reports where the intake runner flaps are, letting the PCM confirm the runners moved as commanded. The engine still runs; a fault usually means minor power loss and is typically caused by a short to power, bad wiring, or a failed sensor.
Can I keep driving? Yes — the engine starts and runs, though you may notice mild power loss or rough idle. It's mainly a sensor/feedback fault; repair it to restore full performance and pass emissions.
Common symptoms
What you'll notice
- Check-engine light on
- Slight loss of power or hesitation
- Rough idle in some cases
- Often little noticeable change in driving
Common causes
Most likely first
- Intake manifold runner position sensor signal shorted to voltage (reading high)Likely
- Wiring or connector fault in the position sensor circuit on bank 2Common
- Faulty intake manifold runner position sensorCommon
- Stuck runner flaps or a failed IMRC actuator giving an implausible positionLess often
- Faulty powertrain control module (PCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the runner position sensor wiring and connector on bank 2 for a short to power or corrosion.
- Compare the sensor's live reading to the commanded runner position with a scan tool.
- Verify the runner flaps and actuator move freely; clean carbon or repair as needed.
- Replace the position sensor if it reads high with good wiring.
- Clear the code and re-test; if it persists, have the PCM checked.
