What Does C1925 Mean?
The steering module has detected a general circuit failure in the VAPS solenoid actuator return circuit. The return circuit completes the electrical loop from the solenoid back to the module, enabling current monitoring and closed-loop control. A failure here prevents the module from properly regulating solenoid current, degrading steering assist accuracy.
Common Causes
35%
Damaged return wire between the VAPS solenoid and the steering module
30%
Corroded or loose terminal at the solenoid connector return pin
25%
Internal solenoid fault affecting the return current path
10%
Module internal current sensing circuit failure on the return path
Diagnostic Steps
1
Step 1: Measure resistance on the return wire from the solenoid connector to the module connector. Compare to the output wire resistance; both should be near 0 ohms.
2
Step 2: Check the solenoid coil resistance including both output and return connections to verify the complete circuit.
3
Step 3: Inspect the return wire for damage, particularly at points shared with the output wire harness routing.
4
Step 4: Verify connector terminals are clean, tight, and fully seated on both ends of the return circuit.
5
Step 5: If all wiring checks pass, monitor the module's current sensing values to determine if the module's internal sense circuit is at fault.

The most common cause of C1925 (VAPS Solenoid Actuator Return Circuit Failure) is: Damaged return wire between the VAPS solenoid and the steering module
Typical repair costs for C1925 range from $100 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
A return circuit failure prevents accurate solenoid current control, causing unpredictable steering assist levels. Steering effort may vary unexpectedly, creating a safety hazard during driving.
