Fault in the right front wheel speed sensor or deceleration sensor — incorrect signal in the ABS/VSC system.

OBD-II (EN): Right Front Wheel Speed Sensor or Deceleration Sensor Malfunction

Code C1160 indicates an incorrect signal from the right front wheel speed sensor or deceleration sensor, causing the ABS and traction control systems to disable. The cause may be a faulty sensor, chafed wiring harness, or damaged tone ring on the hub. Due to the direct impact on braking performance, prompt diagnosis at a workshop equipped with a professional ABS scanner is recommended.

Symptoms

Illuminated ABS and/or VSC (Vehicle Stability Control) warning light, lack of ABS braking assistance during hard braking, possible deactivation of the traction control system (TRC), unstable vehicle behavior on slippery surfaces, in some cases illuminated check engine or BRAKE warning light.

Possible causes

• Damaged or contaminated right front wheel speed sensor (Hall effect or magnetic sensor) • Open circuit or short circuit in the wheel speed sensor wiring harness • Damaged tone ring (encoder ring) on the hub or axle shaft • Malfunction of the ABS/SKID ECU control module • Incorrect supply voltage or ground for the ABS module • In vehicles with active suspension or VSC system — fault in the deceleration sensor (longitudinal accelerometer)

Does code C1160 require professional diagnostics?

The code alone is not enough. To find the cause, you need to read live data, check freeze frame conditions, and compare with vehicle behavior. Book a diagnostic session.
