C1165
WysokiRight rear wheel speed sensor error – circuit damage. The ABS module is not receiving a correct signal from the right rear wheel speed sensor, which may deactivate the ABS and traction systems.
OBD-II (EN): Right Rear Wheel Speed Sensor Circuit Malfunction
Code C1165 indicates a problem with the right rear wheel speed sensor, a key component of the ABS and traction control systems. Its failure can deactivate active safety systems, which is particularly dangerous on wet or icy roads. We recommend a visit to a diagnostic workshop as soon as possible – causes can range from a damaged wire to a worn wheel bearing hub.
Symptoms
• Illuminated ABS and/or ESP/TCS warning light on the dashboard • Deactivation of the anti-lock braking system (ABS) and traction control • Possible deactivation of the electronic stability control system (ESP) • Harder or unstable braking on slippery surfaces • Possible warning message on the onboard computer • In some vehicles, speed limitation or entry into limp mode
Possible causes
• Damaged or contaminated right rear wheel speed sensor (e.g., corrosion, cracked housing) • Open circuit or short circuit in the sensor wiring harness (mechanical damage, chafing) • Worn or damaged tone ring (encoder) on the axle shaft or wheel hub • Loose or corroded ABS sensor electrical connector • ABS module failure (rare – after excluding other causes) • Excessive wheel bearing play causing an irregular sensor signal

Does code C1165 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.
