Code C1237 Lexus Description
The C1237 code for Lexus vehicles indicates a fault with the speed sensor rotor. The speed sensor rotor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. This sensor is responsible for measuring the speed of each wheel and sending this information to the vehicle's electronic control unit (ECU). The ECU uses this data to determine if any wheel is rotating at a different speed than the others, which could indicate wheel slippage or lock-up.
Common Causes of C1237 Lexus
- Damage to the speed sensor rotor due to road debris or corrosion
- Electrical connection issues between the sensor and the ECU
- Faulty wiring or connectors in the ABS system
- Malfunctioning ABS control module
- General wear and tear on the speed sensor rotor over time
Symptoms of C1237 Lexus
