What Causes the Power Steering Failure in Focus?
2 Answers
Directional machine failure light is on due to the lack of medium in the vehicle's power system, leading to mechanical power failure. Replacing the internal power steering fluid can solve the problem. The reasons for Focus steering failure are as follows: 1. There is a large amount of air in the power steering system, causing abnormal car steering; 2. Foreign objects in the steering hydraulic pipeline cause the steering pump flow control valve to stick; 3. Loose connections in the power steering system lead to steering fluid leakage; 4. Excessive wear of the steering gear piston cylinder, poor sealing of the oil seal, or adhesion or damage of the control valve. Extended information: The role of the car power steering pump: 1. Reduce the driver's operating intensity; 2. Improve maneuverability; 3. Ensure the safety of the steering system and the driver's steering feel when the vehicle is driving at high speed.
I found that when the power steering on the Focus fails, the steering wheel suddenly becomes extremely heavy, feeling like driving an old-fashioned truck. This is usually caused by sensor issues—when the torque sensor under the steering wheel gets dusty or loose, it can't read data accurately and cuts off the power assist. It could also be due to the electric power steering motor overheating and burning out, especially during summer traffic jams. I've also encountered blown fuses—just pop the hood, check the fuse box, locate the corresponding headlight or steering fuse, and replace it. Loose wiring connections should also be inspected; use a multimeter to check if the current is normal. Of course, a bug in the control unit (ECU) could also be the culprit, which requires scanning for error codes with a diagnostic tool. In any case, safety comes first. If you feel the steering is laborious, pull over immediately to inspect or call a tow truck to take it to a professional repair shop—don't push it on the highway.
