The P2022 fault code indicates an issue with the Intake Manifold Runner Position Sensor or Switch Circuit for Bank 2. This component plays a critical role in regulating air flow into the engine, enhancing performance and efficiency. When this fault code is triggered, the engine control module (ECM) detects that the runner position sensor is reporting a high voltage signal when it shouldn't be.

What are the symptoms of the P2022 code?

• Check Engine Light illuminated on the dashboard
• Reduced engine performance and efficiency
• Erratic engine behavior or hesitation during acceleration
• Increased fuel consumption
• Engine may struggle to idle properly

What causes the P2022 code?

• Faulty Intake Manifold Runner Position Sensor
• Wiring issues or short circuits in the sensor circuit
• Poor connections or corroded terminals
• Intake manifold leaks affecting sensor readings
• ECM malfunction or programming issues

How to fix P2022?

• Inspect the wiring and connectors of the intake manifold runner position sensor for any signs of damage or corrosion.
• Replace the Intake Manifold Runner Position Sensor if it is found to be malfunctioning.
• Clear any engine codes and perform a road test to ensure the issue is resolved.
• If problems persist, consider testing the ECM for faults or programming issues.
