How is fault code C0051 fixed?

A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Read the live wheel speed data on a proper ABS scanner and drive the car. Watch the right rear figure against the other three. If it drops to zero, spikes, or lags the others, you've found your wheel 2. Get the right rear off the ground and inspect the sensor and its tip. Pull it out, clean off the metallic crud, and check the air gap. A lot of these are just contamination 3. Wiggle-test the loom and connector with the scanner connected. If the reading flickers when you flex the wire near the trailing arm, the harness is your problem 4. Check the connector for green corrosion or trapped water, a regular cause on cars over ten years old 5. Measure the sensor with a multimeter. Active sensors should show a small voltage swing as you spin the wheel by hand. Passive types have a resistance figure, usually around 1,000 to 2,000 ohms, check against spec for your model 6. Spin the wheel and look at the reluctor ring through the sensor hole or behind the hub for missing or rusted teeth. Clear t
