Start the car and drive it at a slow speed for a few moments. Lightly tap on the brake pedal. If the ABS light comes on after you tap on the brake pedal, it is an indication of a problem with the vehicle’s solenoid. You should also notice pressure on the brake pedal when you lightly tap it to bring the car to a stop.
Can you test a ABS sensor with multimeter?
With an ABS sensor disconnected you can probe the terminals with a multimeter, eliminating the need to remove the sensor from the vehicle. Both passive (2-wire) and active (2 or 3-wire) ABS sensors can be tested for basic functionality with a multimeter. Research which type of sensor your vehicle has before proceeding.

How do you test a transmission speed sensor?
Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor’s wire coupling. Using the multimeter’s voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.
How do I test a sensor with a multimeter?
Multimeter Test: Voltage
- Reconnect the sensor’s power source.
- Disconnect the power wires at the sensor (Point C in the diagram) or connection point closest to the sensor (Point B, if the cable to your sensor cannot be disconnected at the sensor).
- Maintain the same probe – multimeter connections.
