This summary uses the existing diagnostic information shown in full below.
The car's computer is getting a signal that the back left wheel's speed sensor is sending too much power, which might mean something is wrong with the sensor or its wires.
This code indicates a high voltage signal from the rear left wheel speed sensor, suggesting a potential issue with the sensor or its circuit.
The C1208 code is triggered when the ABS (Anti-lock Braking System) module detects a high voltage condition in the rear left wheel speed sensor circuit. This could be due to issues such as a short circuit, damaged wiring, or a faulty sensor.
• ABS warning light illuminated
• Loss of ABS functionality
• Inconsistent speedometer readings
• Faulty rear left wheel speed sensor
• Damaged or corroded wiring or connectors
• Short circuit in the sensor circuit
ABS: Anti-lock Braking System, a safety system that prevents the wheels from locking up during braking.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Inspect the rear left wheel speed sensor and wiring for damage.
• Check the sensor connector for corrosion or loose connections.
• Test the sensor's voltage output with a multimeter.
• Replace the faulty wheel speed sensor.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Honda Accord
• Ford Fusion
• Regularly inspect wheel speed sensors and wiring.
• Keep wheel wells clean to prevent debris buildup.
• Perform routine ABS system checks.
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Get the ABS system checked by a professional.
• Monitor for any changes in braking performance.
Check with the vehicle manufacturer for warranty coverage on ABS components.
This code has been associated with issues in vehicles with high mileage or those frequently driven in harsh conditions.
Moderate – While the vehicle is still drivable, the ABS system may not function properly, affecting braking safety.
Driving with a malfunctioning ABS system can increase the risk of accidents, especially in wet or slippery conditions.
• Vehicle parked on a level surface
• Ignition in the 'on' position
The rear left wheel speed sensor is located near the brake rotor of the rear left wheel.
Q: Can I drive with a C1208 code?
A: While the vehicle is still drivable, it's not recommended to drive long distances without addressing the issue, as the ABS system may not function properly.
Q: How do I reset the ABS light?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, the ABS light should stay off.
