The ABS sensor (wheel speed sensor) reads how fast each wheel is turning. When one fails you get an ABS warning light, traction control disabled, and sometimes a speedometer issue. Here is what replacement costs in 2026.
Standalone sensors $30-$120. Hub-with-sensor assembly $100-$300.
30-45 min standalone sensor. 1-2 hours hub replacement or rusted-in sensor.
| Vehicle Class | Typical Range | Notes |
|---|---|---|
| Compact car | $100 - $250 | Easy bolt-in sensor |
| Sedan | $130 - $300 | Standard wheel hub |
| SUV / Crossover | $160 - $360 | Sometimes integrated with hub |
| Truck | $180 - $400 | Larger hubs, heavier sensors |
| Luxury / European | $250 - $600 | Often hub-integrated, OEM only |

It reads each wheels rotational speed. The ABS module uses that data for anti-lock braking, traction control, and stability control.
Yes, but you lose anti-lock braking and traction control. Standard braking still works. Fix it before winter or any track use.
On many newer cars, yes - the speedo uses the same sensor. On older vehicles, no - the speedo is separate.
ABS codes use the B-prefix (chassis codes) instead of P-prefix (powertrain). Both can be read by a basic OBD2 scanner with ABS support.
Not in normal conditions. It becomes dangerous on ice, gravel, or hard braking when ABS would normally engage.
