C0034 Right Front Wheel Speed Sensor

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

Covers the right front wheel speed sensor and its circuit, the mirror of C0031. The active sensor reports wheel rotation to the ABS/ESC module for anti-lock, traction and stability control and 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 C0034 on the F-Pace and XE with several fault sub-types (C0034-2F, -29, -41) alongside C0031 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
