SSANGYONG 4893034100
Overview & Operating Principle
▲

The SENSOR WHEEL SPEED is a magnetic or Hall-effect device mounted at each wheel hub or knuckle that monitors the rotational speed of the wheel and transmits a continuous pulse signal to the ABS control module, traction control system, and stability control unit. The sensor reads the tooth pattern of a reluctor ring — either a pressed-steel tone ring on the hub or an integrated magnetic encoder ring on the inner bearing seal — and converts rotational speed into a frequency signal used by the ECU to detect wheel lock-up, slip, and speed differential between axles.

This unit — SSANGYONG 4893034100 — is manufactured to OEM-equivalent specifications: signal output waveform, air gap tolerance, connector pinout, and operating temperature range are matched to the original part. Supplied as a direct plug-and-play replacement requiring no ECU recalibration for standard fitment. Available wholesale from 7.84 USD, MOQ 45 pcs, production lead time 15-20 days.

Wheel speed sensors fail gradually through cable chafing, connector corrosion, or contamination of the sensing face with metallic debris from worn brake components. Before replacing the sensor, inspect the reluctor ring for cracks, missing teeth, or heavy rust — a damaged ring will cause erratic ABS codes even with a new sensor installed.

Symptoms & Diagnostics
▲
ABS warning light illuminated on the instrument cluster — typically accompanied by codes C0031, C0034, C0037, C0040 or manufacturer-specific equivalents identifying the affected wheel.
Traction control (TCS) and electronic stability control (ESC/ESP) warning lights active simultaneously — these systems share wheel speed data and disable when a sensor signal is lost.
ABS activating at low speed or on dry roads during normal braking — indicates an intermittent or erratic signal from a partially failed sensor or damaged reluctor ring.
Speedometer reading incorrect or dropping to zero intermittently — on vehicles where the ECU derives vehicle speed from wheel speed sensors rather than a dedicated VSS.
Harsh or delayed automatic transmission shifts — the TCU uses wheel speed data for shift scheduling; a missing signal can cause the transmission to default to a protective shift map.
No fault codes present but ABS light on after wheel bearing replacement — indicates the new bearing’s integrated encoder ring is misaligned or the sensor air gap is outside specification.

Installation Tips
▲
  1. Raise and support the vehicle safely on axle stands, remove the wheel, and clean the sensor mounting area with a wire brush to remove rust and brake dust before attempting to unbolt the sensor.
  2. Disconnect the sensor connector at the harness clip point — release the locking tab carefully, as brittle plastic connectors on high-mileage vehicles break easily. If corroded, apply electrical contact cleaner before attempting separation.
  3. Remove the sensor retaining bolt (typically M6 or M8, 8–12 Nm) and extract the sensor. If the sensor is seized in the hub bore, use a sensor removal kit or tap the body gently with a copper hammer — never use steel on the sensor body.
  4. Inspect the reluctor ring for missing teeth, cracks, or heavy corrosion before installing the new sensor. A damaged ring must be replaced — it is the most common cause of continued ABS faults after sensor replacement.
  5. Verify the air gap between the new sensor tip and the reluctor ring using a feeler gauge if the application specifies a gap (typically 0.2–1.5 mm). Passive magnetic sensors are air-gap sensitive; Hall-effect sensors are more tolerant.
  6. Install the new SENSOR WHEEL SPEED (SSANGYONG 4893034100), torque the retaining bolt to specification, route and clip the cable to prevent contact with the CV joint or brake caliper, reconnect the connector, and use an OBD-II scanner to clear ABS codes and verify no new codes after a short drive.
Tools: OBD-II scanner with ABS code access, 8–10 mm socket, torque wrench, wire brush, feeler gauge, sensor removal kit, electrical contact cleaner.
Frequently Asked Questions
▲
Should all four wheel speed sensors be replaced at the same time?
It is not necessary to replace all four sensors simultaneously unless the vehicle has very high mileage and multiple sensors are showing degraded signal output. Confirm the faulty wheel with a scanner before ordering — the fault code will identify the exact corner. ok.parts supplies individual sensors and axle sets at wholesale MOQ from 7.84 USD per unit.
Is any calibration or ECU adaptation required after replacing a wheel speed sensor?
No calibration or ECU coding is required for a standard wheel speed sensor replacement. After installation, clear any stored ABS, TCS, or ESC fault codes using an OBD-II scanner and perform a short road test above 30 km/h to allow the ABS module to confirm consistent signals from all four corners. The system will self-validate automatically.
How does the OEM-equivalent aftermarket unit compare to the genuine OEM part?
OEM-equivalent units in this catalogue replicate the current OEM design geometry and material specification. Quality is verified against OEM cross-reference data. When ordering in bulk, confirm with our team that the specification matches the latest OEM revision for your application.
Is white-label or custom packaging available for wholesale orders?
Yes. ok.parts works directly with the manufacturing facility and can accommodate neutral white-label packaging or fully branded packaging with your company logo, part numbers, and barcode. Minimum order quantities and lead times for custom packaging may differ from standard stock. Contact the team via the inquiry form to discuss your specific requirements.
Frequently Replaced Together
PartReason for Combined Replacement
Wheel Bearing Hub Assembly
OEM ref. varies by axle position		On modern vehicles the reluctor ring is integrated into the wheel bearing inner seal. A worn bearing with a damaged encoder ring will cause continued ABS faults after sensor replacement — inspect bearing play and replace if worn.
ABS Sensor Wiring Harness
Application-specific		The sensor cable is routed along the suspension and subject to chafing, cracking, and corrosion over time. A damaged harness is a common cause of intermittent ABS codes even after sensor replacement — inspect the full cable run and replace if insulation is compromised.
Reluctor Ring (Tone Ring)
OEM ref. varies by hub type		On older vehicles with a separate pressed-steel tone ring, corrosion and impact damage can cause missing or deformed teeth that produce erratic sensor signals. Replace the tone ring if teeth are damaged — a new sensor will not resolve the fault if the ring is defective.
