• The ABS sensor is typically located in each wheel hub/rotor on a four channel ABS system. Some rear wheel drive applications have the sensor mounted in the rear differential
  • Generally these sensors will fail as a result of clogging from metallic debris, brake dust or dirt due to exposure to the harsh elements
  • A failing sensor can illuminate the MIL or ABS warning lamp, and may cause failure of the anti-lock braking system to operate safely and properly
  • An ABS sensor can be visually inspected and the wire winding and sensor harness can be tested for opens, shorts and proper factory specified resistance with an ohmmeter

ABS Sensor Testing – See how the rest of the pack stacks up

We left no stone unturned; performing extensive laboratory and real life testing that included measuring and comparing shaft speed vs. delta voltage, output voltage and variation to OE, magnetic field strength, air gap, output wave form, pulse width as well as a complete physical product comparison to OE.

The Findings

Competitor's ABS Sensors

  • No Consistency in signal output performance.
  • Inferior materials in the magnetic circuit which results in low voltage output and can lead to ABS system failure.
  • No Consistency in critical sensor dimensions which establish the gap between the sensor tip and target wheel which can lead to the sensor tip hitting the spinning target wheel causing sensor damage.
  • Inadequate quality inspection and product testing.
  • No Consistency in matching OE for form, fit and critical function.

BWD®: ABS Sensor #ABS1443 (GM 02-95; ranked in the top 10 sellers) matches OE for output voltage, resistance, trigger wheel gap and all critical fit, form, and function measurables.

Competitor: 29%-51% lower voltage output when compared to OE leading to potential ABS system failure. Incorrect mounting bracket does not match OE.

BWD®: ABS Sensor #ABS309 (Ford 09-95; ranked in the top 10 sellers) matches OE for output voltage, resistance, trigger wheel gap and all critical fit, form, and function measurables.

Competitor: 45%-74% lower voltage output when compared to OE leading to potential ABS system failure. Inconsistent winding resistance, electrical inductance and magnetic field orientation resulting in poor sensor performance. Inconsistent gap between sensor tip and trigger wheel leading to potential sensor tip damage.
