VAPS Solenoid Return Circuit Open
The C1926 code indicates an open circuit in the return line of the Variable Assist Power Steering (VAPS) solenoid actuator. This system hydraulically adjusts steering effort based on vehicle speed. An open circuit means the control module detects no electrical continuity in the solenoid return wire, preventing proper monitoring and control of the solenoid, which affects steering effort variation.
1. Commonly Affected Makes
2. Most Common Causes
- Damaged or internally open VAPS actuator solenoid
- Broken or disconnected return circuit wiring
- Corroded, bent, or loose terminals in the solenoid electrical connector
- Internal failure of the Power Steering Control Module (PSCM)
3. Symptoms You Will Notice
- Steering effort does not vary with vehicle speed
- Steering may feel constantly heavy or light
4. Step-by-Step Diagnosis
Scan for additional codes and check freeze frame data
Visually inspect the VAPS solenoid connector and wiring for damage
Test solenoid resistance and compare to specifications
Check for continuity in the return circuit between solenoid and PSCM
If wiring and solenoid are good, test PSCM output or replace module
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, but steering assist may be fixed at one level, making the vehicle harder to maneuver at low speeds or overly light at high speeds. Have it diagnosed soon.
How much does it cost to fix?▼
Typically $150 to $400, depending on whether the solenoid, wiring, or control module needs replacement.
