Details of the c0037 OBD Code
C0037 code indicates an issue with the left rear wheel speed sensor circuit.
OBD code C0037 means Left Front Wheel Speed Sensor Circuit.
This code is triggered by the Electronic Brake Control Module (EBCM) when an issue is detected with the left front wheel speed sensor circuit.
The EBCM monitors the signals from the wheel speed sensors to control the vehicle’s braking system and stability control.
If the left front wheel speed sensor circuit has a fault, it can lead to issues with ABS operation, traction control, and stability control systems.
