How to Check Lexus RX350 ABS Sensor?

Checking a Lexus RX350 ABS sensor involves a few key steps. First, ensure safety by properly jacking up the vehicle and removing the wheel to access the sensor. Visually inspect the sensor and its wiring for any signs of physical damage, fraying, or corrosion, as these are common failure points. Next, disconnect the sensor's electrical connector and use a multimeter set to ohms (Ω) to measure resistance across its two pins. A healthy passive sensor typically shows resistance between 1,000-2,000 ohms (check specific model specs); an "open line" (OL) or wildly inconsistent reading signals a fault. For newer RX350s with active sensors, resistance tests are often inconclusive. The most reliable method is an OBD-II scanner capable of reading ABS-specific fault codes and live data to pinpoint the exact sensor and verify its signal.
