DTC A032 - Left Front Wheel Speed Sensor Circuit Open Or Shorted To Battery Or Ground: Notes

As a toothed ring passes the wheel speed sensor, changes in electromagnetic field cause sensor to produce an AC voltage signal. Frequency of signal is proportional to wheel speed. Magnitude of signal is directly related to wheel speed and the proximity of the wheel speed sensor to the toothed ring. This distance is also referred to as "air gap"

1. Verifies malfunction is currently present.
2. Identifies visibly damaged wheel speed sensor or circuitry.
3. Checks wheel speed sensor for proper resistance (at room temperature). Tester J 39200 is a DVOM with a 10-megohm input impedance.
4. Ensures wheel speed sensor and sensor ring generate proper voltage.
5. Ensures wheel speed sensor is not shorted to ground.
6. Checks for proper voltage at speed sensor harness connector.
7. Ensures wheel speed sensor circuitry is not internally shorted.
8. Checks for open in circuit 873.
9. Checks for open in circuit 830.
10. Checks for short to ground in both wheel speed signal circuits.
11. Ensures DTC A032 was not set due to poor connection between EBCM and connector C1.
