Code C1917 Mercury Description
The C1917 diagnostic trouble code (DTC) for Mercury vehicles indicates a Steering Electronic Variable Orifice (EVO) Out-Of-Range Fault. This fault occurs when the electronic control unit (ECU) detects that the EVO system is not functioning within the specified parameters. The EVO system is responsible for adjusting the power steering assist based on driving conditions, vehicle speed, and steering input to provide the driver with optimal steering feel and control.
Common Causes of C1917 Mercury
- Faulty EVO sensor or actuator
- Wiring or connection issues in the EVO system
- Low power steering fluid levels
- Mechanical issues with the power steering pump
- Electronic control unit (ECU) malfunction
Symptoms of C1917 Mercury
- Stiff or hard steering at low speeds
- Loose or overly sensitive steering feel
- Steering wheel vibration or wobbling
- Difficulty maintaining control of the vehicle while steering
- Illumination of the power steering warning light on the dashboard
How to Fix C1917 Mercury
- Begin by conducting a thorough inspection of the EVO system, including the sensor, actuator, wiring, and connections.
- Check the power steering fluid level and quality, topping up or replacing as necessary.
- Test the power steering pump for proper operation and pressure output.
- Use a diagnostic scan tool to retrieve and clear the C1917 fault code from the ECU.
- If the issue persists, replace any faulty components in the EVO system, such as the sensor, actuator, or ECU.
