Definition

The OBD2 code C1922 indicates that there is an open circuit in the Variable Assist Power Steering (VAPS) solenoid actuator output, which means the system is not receiving the expected electrical signal to operate the solenoid actuator properly

Common causes

  • Faulty VAPS solenoid actuator
  • Open or damaged wiring in the actuator circuit
  • Poor electrical connections or corroded terminals
  • Failed or malfunctioning vehicle control module (VCM)
  • Blown fuse related to the actuator circuit
  • Grounding issues in the circuit

Common misdiagnoses

  • Faulty VAPS solenoid actuator
  • Wiring issues or damaged connectors
  • Faulty control module
  • Incorrectly diagnosed suspension issues
  • Misinterpretation of related codes
  • Battery or power supply problems
  • Grounding issues in the circuit

Troubleshooting steps

  1. 1. Check the Vehicle's Service Manual

    Always refer to the specific service manual for your vehicle model. It will provide detailed information about the VAPS system and the wiring diagrams

  2. 2. Visual Inspection

  3. 3. Inspect the wiring and connectors associated with the VAPS solenoid actuator. Look for any signs of damage, corrosion, or loose connections

  4. 4. Check for any frayed wires or broken connectors that could cause an open circuit

  5. 5. Test the VAPS Solenoid Actuator

  6. 6. Use a multimeter to check the resistance of the VAPS solenoid actuator. Compare the readings to the specifications in the service manual

  7. 7. If the resistance is out of range, the actuator may be faulty and require replacement

  8. 8. Check the Power and Ground

  9. 9. Verify that the VAPS solenoid actuator is receiving the correct voltage. Use a multimeter to check for power at the actuator connector while the ignition is on

  10. 10. Check the ground connection for the actuator. A poor ground can cause an open circuit

  11. 11. Inspect the Control Module

  12. 12. If the actuator and wiring are in good condition, the issue may lie with the control module (ECM or BCM). Check for any stored trouble codes that may indicate a problem with the module

  13. 13. If necessary, perform a reset or reprogramming of the control module

  14. 14. Check for Other Related Codes

  15. 15. Look for any other OBD-II codes that may be related to the power steering system. Addressing these codes may help resolve the C1922 code

  16. 16. Perform a System Test

  17. 17. If your vehicle is equipped with a diagnostic scan tool, perform a system test to see if the VAPS system is functioning correctly. This may include checking for proper operation of the solenoid actuator

  18. 18. Clear the Code and Test Drive

  19. 19. After performing the necessary repairs, clear the trouble code using a scan tool and take the vehicle for a test drive to see if the code returns

  20. 20. Consult a Professional

  21. 21. If you are unable to diagnose or fix the issue, it may be best to consult a professional mechanic or technician who has experience with your vehicle's power steering system. By following these steps, you should be able to identify the cause of the C1922 code and take appropriate action to resolve the issue
