C0031 Left Front Wheel Speed Sensor

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

Covers the left front wheel speed sensor and its circuit. The sensor, usually an active Hall-effect type, reports wheel rotation to the ABS/ESC module for anti-lock, traction and stability control and for speed-dependent functions. The module monitors the circuit for opens, shorts to power or ground, a signal outside the valid range and a missing signal while the vehicle is moving. Jaguar documents C0031 on the F-Pace and XE with several fault sub-types (C0031-2F, -29, -31, -62) while the ABS warning lamp is lit. A fault disables ABS, traction and stability control and lights the ABS warning lamp while base braking remains.

Likely causes

Wheel speed sensor failed
Open, shorted or chafed sensor wiring
Corroded sensor connector

Symptoms

  • ABS warning lamp on
  • ABS and stability control disabled
  • Speedometer may read erratically
