What is the fault when the ABS and tire pressure monitoring lights are on?

[OJanelle]

The illumination of the tire pressure monitoring light and ABS light indicates a fault in the ABS anti-lock braking system and tire pressure. The detailed reasons and solutions for the ABS and tire pressure monitoring lights being on are as follows: 1. Faulty wheel speed sensor: A computer diagnostic tool can identify which wheel speed sensor is malfunctioning. Solution: Replace the sensor. 2. ABS sensor has not been cleaned for too long: This can prevent the ABS sensor from detecting the wheel speed, triggering the ABS warning light. Solution: Clean the sensor. 3. Faulty wheel speed sensor wiring: Damaged wiring for the wheel speed sensor can also cause ABS faults. Solution: Replace the wheel speed sensor wiring harness.
