This summary uses the existing diagnostic information shown in full below.
The car's computer is confused about which way the front left wheel is spinning. It's like when you can't tell if a fan is blowing air towards you or away from you.
The wheel speed sensor is detecting an implausible direction of rotation for the left front wheel, which may indicate a sensor or wiring issue.
The wheel speed sensor on the left front wheel sends signals to the vehicle's control module to determine the wheel's speed and direction. If the sensor provides a signal that indicates an impossible or incorrect direction of rotation, the system triggers this code.
• ABS warning light on the dashboard
• Traction control system may be disabled
• Unusual braking behavior
• Faulty wheel speed sensor
• Damaged wiring or connector
• Faulty ABS module

Moderate
• Ford Explorer
• Toyota Camry
• Honda Accord
• Regular inspection of wheel speed sensors.
• Avoid driving through deep water or mud.
• Perform regular maintenance checks.
Sensor Issue
• Drive cautiously if the ABS light is on.
• Have a professional diagnose the issue promptly.
Check your vehicle's warranty for coverage on ABS components.
This code has been more prevalent in vehicles with high mileage or those frequently driven in harsh conditions.
Moderate – It is safe to drive for short distances but should be repaired soon to ensure proper ABS function.
Driving with a malfunctioning ABS can lead to reduced braking performance and increased stopping distances.
• Drive the vehicle at a low speed.
• Perform a gentle stop to observe sensor readings.
The left front wheel speed sensor is located near the wheel hub of the front left wheel.
Q: Can I drive with this code?
A: Yes, but it's best to get it fixed soon to ensure your ABS and traction control systems work properly.
Q: Will this affect my car's braking?
A: It might. The ABS might not function correctly, which can affect braking performance in slippery conditions.
