C1925 — VAPS Solenoid Actuator Return Circuit Failure

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Generic

About C1925

C1925 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1925 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1925 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Variable Assist Power Steering (VAPS) system uses a solenoid actuator, controlled by the power steering control module, to vary steering assist based on vehicle speed. The solenoid return circuit provides the ground return path that completes the actuator current loop. DTC C1925 is set when the control module detects a fault in the solenoid actuator return circuit, such as an open or high resistance condition that prevents proper current flow through the solenoid. The VAPS solenoid regulates hydraulic pressure to the steering gear, providing more assist at low speed for parking and less as...
