In new Chevrolet vehicles, specifically on those equipped with an anti-lock braking system, two speed sensors are usually installed. The first is the engine speed sensor. This speed sensor is often mounted on the vehicle's crankshaft and is actually where the speedometer gets its data. The other type of speed sensor used in modern vehicles is the wheel speed sensor. This speed sensor, on the other hand, picks up impulses from the wheels and sends the data to the anti-lock braking system (ABS) ECU. This data is then used by the system to anticipate a condition when the wheels would lock-up.

Now, what happens if these two types of speed sensors fail or malfunctions? Nothing much, probably, in the case of the engine speed sensor. The only complication it will make is that the engine management ECU won't be able to measure the engine speed and thus you won't be able to determine how fast your Chevy is moving through the speedometer. But if the wheel speed sensor is the one that fails, then you are in serious trouble. If this happens, your ABS brakes would become totally useless as there is nothing that will tell the system that your Chevy's brake is already locking up.

So if your Chevy's wheel speed sensor is already malfunctioning, you better replace it at once with a new Chevrolet wheel speed sensor. It will also do you good if you replace the engine speed sensor once you discover it malfunctioning.
