What Does C1926 Mean?
The steering module has detected an open circuit in the VAPS solenoid actuator return circuit. The return path is broken, so current cannot flow through the solenoid even if the output driver is functioning. The solenoid is effectively disabled, and steering assist will default to a fixed (typically heavy) level.
Common Causes
35%
Broken return wire in the VAPS harness from heat or vibration damage near the steering gear
30%
Backed-out or disconnected return terminal at the solenoid or module connector
25%
Internal solenoid open on the return side of the coil winding
10%
Corroded inline junction or splice in the return circuit
Diagnostic Steps
1
Step 1: Measure continuity on the return wire from solenoid connector to module connector. An open confirms the break.
2
Step 2: Check solenoid coil resistance through the return terminal. OL from the return side indicates an internal coil break.
3
Step 3: Inspect the harness for severed or corroded wires near the steering gear and engine bay.
4
Step 4: Verify return terminal is fully seated in the connector and has proper retention force.
5
Step 5: Repair the open and verify steering assist varies properly with vehicle speed during a road test.

The most common cause of C1926 (VAPS Solenoid Actuator Return Circuit Open) is: Broken return wire in the VAPS harness from heat or vibration damage near the steering gear
Typical repair costs for C1926 range from $100 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
An open return circuit disables the VAPS solenoid, causing fixed heavy steering effort. This is especially problematic during parking maneuvers and emergency steering inputs.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1926 to identify the root cause.
