Abs sensor wires are electrical wires that connect an anti-lock braking system (ABS) sensor to the brake system. The ABS sensor detects wheel speed and sends the information to the vehicle’s computer, which then adjusts the brake pressure to maintain stability and control during hard braking.
So can you splice an ABS sensor wire? That is what we’re going to discuss in this article. So stick around until the end to find out what you’ve been looking for.

Can You Splice An Abs Sensor Wire?
You can, but it isn’t recommended to do so. Don’t split them; instead, buy new ones. Just behind the shock tower, the fronts are connected to the harness.
Up along the frame, the rears. Pull the lowest plastic push connector when installing the new ones and leave it out; this should leave room for droop on up to a 4-5″ lift. The wires should not be spliced because they are sensitive to obstruction and resistance.
But if you still want to splice the ABS sensor wires, then here is how to do it.
They aren’t particularly sensitive, so soldering and heat shrink will work just fine. Additionally, I always space out the connections when splicing. Instead of cutting both wires at the same location, space the cuts apart by a few inches.
This will prevent your solders and heat shrinks from being right next to one another, making it less likely that one of them will puncture the heat shrink and cause a problem. Additionally, that prevents the harness from having a large lump in the middle, so once the complicated tubing is put back on, you won’t be able to tell anything was done.
What happens if your ABS wire breaks?
If the ABS wire breaks, then the anti-lock braking system will not work properly. This means that the brakes may not be able to respond quickly enough to prevent the wheels from locking up when you are braking hard, which can lead to loss of control of the vehicle.
Furthermore, the ABS light will come on in the dashboard, which is a warning that the brakes may not be working as intended. If the ABS wire is broken, it is important to have the system checked immediately and have the wire replaced.
If it is not fixed, the brakes may not be able to be used effectively in emergency situations, which can be dangerous.
How to test the ABS sensor wire?
- Set the multimeter to the ohmmeter setting.
- Unplug the ABS sensor wire from the vehicle.
- Connect one probe of the multimeter to one end of the ABS sensor wire.
- Connect the other probe of the multimeter to the other end of the ABS sensor wire.
- Check the continuity. The multimeter should display a reading of zero ohms if the wire is good.
- If the multimeter displays an infinite resistance, the ABS sensor wire is broken.
How to repair the ABS sensor wire?
- Locate the ABS sensor wire. It is typically located near the wheels or in the engine compartment.
- Inspect the wire for any visible signs of damage such as broken insulation, frayed wires, or cuts.
- If the wire is damaged, use a wire cutter to cut away any frayed sections.
- Strip away 1/4 to 1/2 inch of insulation from each wire that needs to be repaired.
- Use a butt connector to join the two exposed wires together.
- Secure the butt connector with electrical tape or heat-shrink tubing.
- Test the newly repaired wire by connecting a multimeter to the two ends and ensuring there is continuity.
How to test the ABS sensor?
- Check the wiring: Check the wiring between the ABS sensor and the ABS controller for any loose connections, broken wires, or corrosion.
- Set up a multimeter: Connect one lead of the multimeter to the body of the ABS sensor, and the other lead to the signal wire coming from the ABS sensor.
- Test resistance: Put the multimeter in ohms mode and check the resistance between the leads.
- Check the voltage: Switch the multimeter to volts mode and check the voltage between the leads.
- Test the signal: Connect one lead of the multimeter to the signal wire and the other to the body of the ABS sensor. Put the multimeter in its AC volts mode, and check the signal coming from the ABS sensor.
