Delphi speed and position sensors are designed for use with any control module
that accepts a digital input. Our sensors use the Hall Effect or magneto resistive
(MR) principles for accurate and clean signal input to the electronic control
module (ECM). The result is more design flexibility to address unique applications
requiring high-temperature operation and extremely stable switch point repeatability
and/or high air gap capability. Our speed and position sensors also maintain optimal
performance during drastic temperature changes for robust, long-lasting sensor
protection thanks to a single-element design. Delphi speed and position sensors
undergo certified electrical testing with industry EMI protection against noise
interference and other sensor output, and feature enhanced sensing functionality
that delivers reduced emissions, improved reliability and superior driveability.
Symptoms of a Failing Speed Sensor vs. ABS Wheel Speed Sensor
Some vehicles may use the same part for both a Speed Sensor and an ABS Wheel Speed Sensor, while others may use two different parts. These parts serve different systems of the vehicle and may fail for different reasons - it is important to replace the proper sensor to fix the underlying issue.
SPEED SENSOR
The Speed Sensor(s) measure rotational speed of the transmission shafts. Common failure symptoms include:
Erratic Speedometer Behavior
Harsh or Improper Shifting
Loss of Cruise Control
Surging or Hesitation
Check Engine Light On
Located in 'Electrical'
ABS WHEEL SPEED SENSOR
The Anti-Lock Brake System (ABS) sensor monitors wheel speed. Common failure symptoms include:
ABS Light On
Brake Pulsing
No / Erratic Traction or Stability Control
No / Erratic ABS Operation
Braking Without Pedal Contact
Located in 'Brake & Wheel Hub'
