Code result
C0052
Left Rear Wheel Speed Sensor Circuit Low
Moderate severity
What it means
Voltage in the left rear wheel speed sensor circuit is below the expected range. Wheel-speed signals feed ABS, ESC, traction control, transmission and odometer — a single dropped signal disables all of these safety functions until repaired.
