3-Pin Wheel Speed Sensor Wire Harness Connector – OEM 13847082 / F223600 / 02821E | Waterproof Female

The OEM 13847082 / F223600 / 02821E are 3-pin waterproof female connectors used in wheel speed sensor (WSS) harnesses for ABS and ESP systems. These cross-referenced part numbers cover the same connector family: 13847082 is the GM/Opel part number, F223600 and F387300 are alternate cross-references, and 02821E is an additional variant reference. The 3-pin configuration carries sensor power, ground, and wheel speed signal circuits. Available bare or with 15cm pre-wired leads.

3-Pin Wheel Speed Sensor Circuit Assignment

• Pin 1 (PWR): 12V power supply to sensor
• Pin 2 (GND): Sensor ground
• Pin 3 (SIG): Wheel speed signal output (square wave, frequency proportional to wheel speed)

Why Wheel Speed Sensor Connectors Fail

Wheel speed sensor connectors are mounted in the wheel arch — one of the harshest environments on the vehicle. Road spray, salt water, brake dust, and stone impacts all stress the connector. The connector is also subject to repeated flexing as the suspension moves. Common failure modes:

• Corrosion: Salt water ingress causes pin corrosion, increasing contact resistance and causing intermittent ABS faults
• Locking tab failure: The locking tab breaks from repeated removal during brake service, causing the connector to work loose
• Wire chafing: The harness chafes against suspension components, causing wire damage near the connector

Fault Codes from WSS Connector Faults

• C0035: Left Front Wheel Speed Sensor Circuit Malfunction
• C0040: Right Front Wheel Speed Sensor Circuit Malfunction
• C0045: Left Rear Wheel Speed Sensor Circuit Malfunction
• C0050: Right Rear Wheel Speed Sensor Circuit Malfunction
• C0110: ABS pump motor circuit fault (if ABS ECU loses all wheel speed signals)
• U0121: Lost communication with ABS control module

Frequently Asked Questions

Q: My ABS light is on but the brakes work normally — is this the connector?
A: Yes. A corroded WSS connector causes the ABS ECU to detect a circuit fault and illuminate the ABS warning light, while the base braking system continues to work normally (ABS is disabled). Replace the connector and clear the fault code to restore ABS function.

Q: How do I know which wheel’s connector is faulty?
A: The fault code identifies the specific wheel position (C0035 = left front, C0040 = right front, etc.). Inspect the connector at the identified wheel position first.
