What is the reason for the alarm still going off after replacing the right rear wheel sensor?

The reason the alarm still goes off after replacing the right rear wheel sensor is that the computer board has not cleared the alarm or matched the new sensor. Sensor Introduction: A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control. Characteristics of sensors: miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. It is the primary link in achieving automatic detection and automatic control. The existence and development of sensors give objects senses such as touch, taste, and smell, making objects gradually come to life. They are usually divided into ten categories based on their basic sensing functions: thermal elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magnetic-sensitive elements, humidity-sensitive elements, sound-sensitive elements, radiation-sensitive elements, color-sensitive elements, and taste-sensitive elements.
I've dealt with similar issues before. Even after replacing the sensor, the warning light still comes on, which is quite annoying. It could be that the new sensor itself is faulty—some aftermarket parts on the market are of poor quality, and it's a gamble whether they'll work. Another possibility is that the connector wasn't plugged in securely during installation or the pins were bent, leading to poor signal transmission. Aging or damaged wiring harnesses can also cause short circuits or breaks, especially in the right rear wheel area, which often gets covered in mud and water, making it more prone to corrosion. If the ABS module is malfunctioning or needs a reset, the system might not update even after replacing the sensor. Some vehicle models require a diagnostic tool to clear fault codes or perform calibration. Tire slippage or imbalance can sometimes interfere with the warning system as well. I recommend checking the connectors and wiring yourself first. If everything seems fine, take it to a professional shop to read the codes and diagnose the issue promptly—don't compromise on driving safety. ABS problems are serious.
