What should the resistance of a wheel speed sensor be?
The typical reading for a passive wheel speed sensor is between 1,000 and 2,500 ohms. This is a normal range for all passive sensors. The specification for active sensors is between 1,000 and 2,500 ohms.
What happens if you unplug ABS sensor?
Removing a wheel speed sensor will disable ABS—and sometimes, stability control. If your car has a yaw sensor, you can unplug that for results. You can also try simply unplugging the ABS module, though that could adversely affect your car’s braking performance.
How many ohms should a ABS sensor have?
On a passive ABS sensor, measuring resistance across the signal and ground leads generally produces a reading of 800-2000 ohms. A steady reading within this range indicates a good sensor. If the resistance is constantly changing or increasing on the meter, the sensor is faulty.
What is the resistance of an ABS sensor?
Most abs sensors on cars have a resistance of approx 1000 -1500 ohms .the reading that you have is correct ,but when fitted to the car the cable twists & flexes and can possibly give you an open circuit condition which is enough for the abs Ecu to detect as a fault.

How many ohms do you need to check ABS?
It is 50 ohms on most cars. If you have ABS on the front wheels only you will be checking the sensors for the front wheels only. If you have ABS on all four wheels you will be doing this for all four wheels. Consulting the manual will tell you which arrangement you have.
How can I tell if my car has an ABS sensor?
With a little effort you might save hundreds of dollars. Look in your car manual to see what the resistance is on tour Anti-locking Breaking System (ABS) sensor. It is 50 ohms on most cars. If you have ABS on the front wheels only you will be checking the sensors for the front wheels only.
What is the fault of the ABS system?
If you have ABS, the fault is often the ABS sensor. This sensor tells the braking system how fast the wheels are spinning–and the braking system uses this information to come between you and the brakes when you are doing something that is going to lock them up.
