What Does C1922 Mean?
The steering module has detected an open circuit in the VAPS solenoid actuator output circuit. A complete electrical break prevents the module from energizing the steering assist solenoid. The solenoid will be de-energized, typically resulting in maximum hydraulic bypass and very heavy steering effort at all speeds.
Common Causes
35%
Broken wire in the VAPS output harness near the steering gear from heat and vibration fatigue
30%
Disconnected or backed-out terminal at the solenoid or module connector
25%
Open VAPS solenoid coil from thermal damage or internal corrosion
10%
Corroded inline splice or junction in the VAPS circuit
Diagnostic Steps
1
Step 1: Measure VAPS solenoid resistance at its connector. An OL reading confirms an open coil requiring solenoid replacement.
2
Step 2: If the coil is good, test continuity of the output and return wires from solenoid to module connector.
3
Step 3: Inspect the harness near the steering gear, subframe, and engine for heat damage or severed wires.
4
Step 4: Check connector terminals for proper seating and retention force.
5
Step 5: Repair the open and verify the solenoid responds to module commands. Road test to confirm speed-sensitive assist returns.

The most common cause of C1922 (VAPS Solenoid Actuator Output Circuit Open) is: Broken wire in the VAPS output harness near the steering gear from heat and vibration fatigue
Typical repair costs for C1922 range from $100 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
An open VAPS output circuit typically results in very heavy steering effort. This makes parking and low-speed maneuvering difficult and can be dangerous in emergency steering situations where quick input is needed.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1922 to identify the root cause.
