C1925 – OBD-II DTC

OBD-II DTC C1925 – VAPS Solenoid Actuator Return Circuit Failure

DTC C1925 meaning

DTC C1925 refers to a diagnostic trouble code indicating a failure in the VAPS (Variable Assist Power Steering) solenoid actuator return circuit. This code is generated when the vehicle’s onboard diagnostic system detects an issue with the electrical circuit responsible for returning signals from the VAPS solenoid actuator to the control module. The VAPS system is designed to adjust the steering effort based on vehicle speed and driving conditions, enhancing steering responsiveness and comfort.

DTC C1925 symptoms

Common symptoms associated with DTC C1925 may include:

• Steering feels heavier or lighter than normal.
• Inconsistent steering response.
• Warning lights illuminated on the dashboard, such as the power steering or check engine light.
• Unusual noises from the steering system.
• Difficulty in steering, especially at low speeds.

DTC C1925 causes

Several factors can lead to the occurrence of DTC C1925, including:

• Faulty VAPS solenoid actuator.
• Wiring issues, such as damaged or corroded wires in the return circuit.
• Poor electrical connections or loose connectors.
• Malfunctioning control module.
• Software issues within the vehicle’s control systems.

DTC C1925 seriousness

The seriousness of DTC C1925 can vary based on the symptoms experienced. While it may not cause immediate safety concerns, it can lead to:

• Reduced steering performance, making the vehicle harder to control.
• Increased wear on steering components.
• Potential for further electrical issues if not addressed.

It is advisable to diagnose and repair the issue promptly to ensure safe vehicle operation.
