C0558Right Rear Wheel Speed Sensor A Incorrect Component Installed

C0558 means the anti-lock brake system (ABS) module has detected that the right rear wheel speed sensor it sees electrically does not match the component the vehicle was built with. The module compares sensor signal characteristics and learned configuration data, and it flags this code when the installed sensor's electrical signature is outside the expected range for that position.

Symptoms you may notice

Anti-lock brake system (ABS) warning light illuminated on the dashboard
Traction control or stability control warning light also on, since those systems share wheel speed data
ABS and traction control disabled, though normal base braking usually remains
Intermittent warning light that may reset after a key cycle and return later
Often no symptoms besides the warning light, with no change in pedal feel or braking performance

Common causes, most likely first

An aftermarket or incorrect wheel speed sensor installed at the right rear position
A right rear sensor from a different trim, axle, or production variation that looks identical but has different internal electronics
Corrosion or poor contact at the right rear sensor connector causing the module to misread the sensor's electrical signature
Damage to the sensor pigtail or harness that alters resistance or signal characteristics
A replacement sensor installed without the required configuration or calibration step on vehicles that learn sensor type
A faulty ABS module that incorrectly flags a correctly installed sensor
Contamination or debris on the sensor tip or tone ring that changes the signal the module evaluates

How to diagnose and fix it

Scan all modules and record every stored and pending code before clearing anything, so the full fault context is preserved
Inspect the right rear wheel speed sensor connector and harness for corrosion, pushed pins, or chafing, and repair as needed
Verify the installed sensor is the correct part for the vehicle's build data by comparing the part number on the sensor to the catalog listing for that VIN
Check live wheel speed data on a road test to confirm the right rear signal is present, consistent, and matches the other three wheels
If the sensor is aftermarket or of unknown origin, replace it with the correct OEM-equivalent sensor for that position
Perform any required sensor learn or configuration procedure with a capable scan tool after replacement
Clear codes and complete a full drive cycle to confirm the code does not return

Why the right rear sensor gets misidentified

This code is frequently set by a perfectly functional aftermarket sensor whose internal resistance or signal profile differs from the original, so replacing it with another cheap sensor repeats the fault.
A sensor that fits the connector and mounts correctly can still be the wrong component, because the ABS module evaluates electrical characteristics rather than physical fit.
Corroded terminals at the right rear connector can mimic an incorrect sensor by shifting the resistance the module measures, so inspect the connector before condemning the sensor.
On some vehicles the ABS module must be told which sensor type is installed, and skipping that configuration step leaves the code stored even with the right part.
A failing wheel bearing or damaged tone ring at the right rear can distort the signal enough that the module misinterprets it as the wrong sensor, so check the tone ring as well.

Can I keep driving with C0558?

The vehicle remains safe to drive at normal speeds because base braking is unaffected, but ABS and traction control are disabled, so avoid hard braking, slippery surfaces, and towing until the fault is repaired.
