Left Front Wheel Speed Sensor Circuit Range/Performance
The signal from the left front wheel speed sensor is implausible relative to the other wheels. Typical causes are excessive air gap, contaminated tone ring or partial sensor failure.
Affected components
- Wheel speed sensor fl
- Tone ring
- Hub bearing
Common causes
- High likelihood: Metal debris on tone ring (magnetic encoder)
- Medium likelihood: Sensor air gap too large
- Medium likelihood: Sensor intermittent at temperature
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
