How do you diagnose a bad ABS sensor?
Bad ABS Wheel Speed Sensor Symptoms
- Illuminated Warning Lights. Your dashboard contains a variety of important lights that alert you to danger.
- Pulsating Brake Pedal while braking.

Can AutoZone read ABS codes?
Unfortunately, the only way to check whether or not the problem is with the ABS is to go and get the codes of your car read. AutoZone can scan your codes as part of our Fix Finder service, or you can do it yourself if you already have a scan tool.
What voltage should be at ABS sensor?
With the sensor disconnected, connect the positive lead to the signal wire and the negative lead to the other side that is the ground for the ABS module. This voltage comes directly from the ABS module and will be between 1.5 and 5 volts. This is the bias voltage from the ABS module.
What ohms should an 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.
How can I tell if my ABS module is bad?
Signs Of A Faulty ABS Module
- The ABS Warning Light Glows. This is the most common sign of problems with the ABS system.
- The Brakes Lock Up. The ABS system is specifically designed to prevent any wheel from locking up during heavy braking.
- An Unresponsive Brake Pedal.
- Increased Pedal Effort.
- Speedometer Failure.
What happens if you remove the ABS fuse?
In summary, the brakes will operate as normal, but the vehicle will not have ABS engage in a situation that would otherwise operate ABS. This could result in locking of the wheels, increasing stopping distance and more importantly, affecting the ability to steer when braking and locking the wheels.

How does the ABS system work on a Dodge Caravan?
Your Caravan’s ABS system uses a system of sensors to determine wheel speed when braking. If one of the wheels is starting to lock up, it’ll apply the maximum amount of brake to that wheel in order to keep it from sliding. Wheels that are turning will slow a vehicle faster than a locked wheel.
How to tell if ABS module is bad?
It’d be great if this is the fix. If you connect a tester that reads ABS codes, yet it’s not detecting the module, then the ABS controller (module) is most likely to be bad. I have the same problem with my Sable, just never replaced the module yet.
Can the OBDII side connect to ABS system?
The OBDII side works fine (no codes), but cannot connect to the ABS system. My thought is it might be an ABS brake module. Anyone have similar experience? What was your corrective action?
