Right Front Wheel Speed Sensor A Correlation
Right-front WSS A reading does not correlate with the other wheel speed sensors during straight-line driving. Wheel-speed signals feed ABS, ESC, traction control, transmission and odometer — a single dropped signal disables all of these safety functions until repaired.
Affected components
- Wss rf
Common causes
- High likelihood: Sensor or tone ring drifted
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
Diagnostic notes
- The malfunction indicator lamp may illuminate
- A drive cycle may be required after repair
- Reduced-power or limp mode may occur
