What are the symptoms of a faulty power steering pump sensor?

A faulty power steering pump sensor may manifest as heavier steering wheel feel, excessive pressure, damage to the hydraulic pump, or damage to sealing components. If the sensor fails, it needs to be replaced immediately. Below is additional information: 1. A sensor is a detection device that can sense the measured information and convert it into electrical signals or other required forms of output according to certain rules, meeting the requirements for information transmission, processing, storage, display, recording, and control. 2. The characteristics of sensors include: miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. They are the primary link in achieving automatic detection and control. The existence and development of sensors give objects senses like touch, taste, and smell, gradually bringing them to life. Typically, sensors are classified into ten major categories based on their basic sensing functions: thermal sensors, photosensitive sensors, gas sensors, force sensors, magnetic sensors, humidity sensors, sound sensors, radiation sensors, color sensors, and taste sensors.
When I first started driving, I noticed the symptoms of a power steering pump sensor failure were particularly obvious. The steering wheel suddenly became very heavy, requiring all my strength to turn, completely different from the usual light and easy steering. The steering system warning light on the dashboard would illuminate, usually a small yellow or red light, alerting you to a system issue. If you listen carefully near the engine bay, there might also be a buzzing or squeaking noise—not loud but annoying, especially noticeable when driving on quiet roads. These symptoms occur because the sensor fails to read data correctly, preventing the power steering pump from automatically adjusting the assist level, causing the entire steering system to malfunction. Ignoring it for too long not only makes driving exhausting but also increases the risk of losing control during parking or sharp turns. So, as soon as I noticed these signs, I pulled over immediately to check and avoid accidents. Later, at the repair shop, the technician said a faulty sensor was the most common cause, and replacing it restored normal function. This experience taught me to pay more attention to sensor conditions during regular maintenance to prevent similar issues.
