Will a car run without wheel speed sensor?
If the wheel speed sensor isn’t working, it won’t send any information to the ECU when there’s a problem. The ABS system won’t know to begin working and you can lose control of your vehicle and cause a crash.
What happens if I unplug my wheel speed 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 do you fix a wheel speed sensor?

- Step 2: Loosen the lug nuts.
- Step 3: Jack the vehicle up and use jack stands.
- Step 4: Remove the old wheel speed sensor.

How much does it cost to replace an ABS sensor?
The ABS wheel speed sensor replacement cost often ranges from $200 to $400 per sensor. You can expect to pay about $100 to $150 for the wheel speed sensor and another $100 to $300 for the labor. ABS wheel speed sensors on luxury vehicles can often cost more, plus some models can be harder to work on, which increases the labor cost.
How do you check wheel speed sensor?
One way to check a suspicious wheel speed sensor is to measure its output voltage. One way to do this is to plug a breakout box into the ABS module’s wiring harness and attach the test leads from a digital volt ohm meter (DVOM) to the appropriate pins for the WSS circuit.
What does a bad wheel sensor do?
Loss of stability and traction control: If it detects a bad wheel speed sensor, the ABS computer will usually disable the stability and traction control systems, as well. On some vehicles, a bad wheel speed sensor may affect other functions as well, such as hill-start assist and roll stability.
Can you drive with a bad ABS sensor?
That is why in general, it is unsafe to drive a vehicle with a broken wheel speed sensor. If the wheel speed sensor becomes damaged or wears out, initially you probably won’t notice much difference in the way your car performs if your ABS light comes on unless you are driving on slippery pavement.
