OBD-II (EN): Left Rear Wheel Speed Sensor Input Circuit Malfunction
Code C1175 indicates a detected failure in the left rear wheel speed sensor circuit – a key component of the ABS and stability control systems. The cause may be a faulty sensor, chafed wiring harness, or worn tone ring on the hub. Due to the impact on braking performance, diagnosis at a workshop is recommended before further driving.
Symptoms
Illuminated ABS warning light on the dashboard, deactivation of the anti-lock braking system (ABS), deactivation of the electronic stability control system (ESP/DSC/VSC), possible illumination of the traction control light (TCS), in some vehicles, limitation of EBD brake system operation.
Possible causes
• Damaged or worn left rear wheel speed sensor (mechanical crack, corrosion, dirt) • Open circuit or short circuit in the ABS sensor wiring harness (cable damage, insulation chafing) • Corroded or damaged sensor electrical connector • Damaged tone ring (reluctor ring) on the hub or axle shaft – chips, rust, metal filings • Excessive mounting clearance of the ABS sensor relative to the tone ring • Less common: damage to the ABS/ESP module
