ActionDescriptionTools Needed
Check for Other CodesUse an OBD-II scanner to check for any additional related codes. These may provide more context about the intake manifold runner system or other issues affecting engine performance.OBD-II Scanner
Measure Voltage in the Sensor/Switch CircuitUse a multimeter to measure the voltage in the intake manifold runner position sensor or switch circuit on Bank 2. Compare the voltage reading to manufacturer specifications to determine if it is too high.Multimeter
Test the Position Sensor or SwitchUse a diagnostic tool or multimeter to test the functionality of the intake manifold runner position sensor or switch. Ensure the sensor or switch is providing accurate signals based on the position of the intake runners.Multimeter, Diagnostic Tool
Inspect Wiring and ConnectorsVisually inspect all wiring and connectors related to the intake manifold runner position sensor or switch for damage, corrosion, or loose connections that could be causing high voltage.Flashlight, Multimeter
Test Circuit ContinuityPerform a continuity test on the wiring circuit to ensure that there are no shorts or open circuits causing the sensor to malfunction. Check for high resistance that could affect voltage readings.Multimeter
Inspect Intake Manifold RunnersVisually inspect the intake manifold runners for any blockages or issues that could be causing incorrect readings from the sensor or switch. Ensure that the runners are operating freely and without obstruction.Flashlight, Intake Cleaner
Repair or Replace Damaged ComponentsIf the sensor or switch is faulty, or if there is damage to the wiring, connectors, or intake runners, repair or replace the affected components to restore proper voltage and functionality.Wiring Repair Kit, Multimeter
Clear the Code and Test DriveAfter making the necessary repairs, clear the P2022 code using an OBD-II scanner. Take the vehicle for a test drive to ensure the issue has been resolved.OBD-II Scanner, Vehicle Owner’s Manual
