P2022
Intake Manifold Runner Position Sensor/Switch Circuit High (Bank 2)
Moderatesensor
Overview
The P2022 diagnostic trouble code means the PCM has identified a intake manifold runner position sensor/switch circuit high (bank 2) problem. This code indicates that a sensor or its circuit is not providing expected readings to the engine management system. Faulty sensor data can cause the PCM to make incorrect adjustments, affecting engine performance.
Symptoms
- Check Engine Light (MIL) illuminated
- ABS or traction control warning light on
- Idle speed fluctuations
- Speedometer reading incorrectly
Common Causes
- Water intrusion in sensor connector
- Incorrect sensor installed
- Faulty PCM/ECM not reading sensor correctly
- Sensor out of calibration
Diagnosis Steps
- 1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
- 2Locate the specific sensor referenced by the code
- 3Inspect the sensor connector for corrosion, damage, or loose pins
- 4Test the sensor output using a multimeter or scan tool live data
- 5Check the wiring between the sensor and the PCM for opens or shorts
