8-97349767-1 8973497671 ABS Wheel Speed Sensor ISO/TS16949 Certified for ISUZU NPR NQR 4HF1 4HE1T 4HG1T 4HK1

Direct-fit OEM replacement sensor (OEM 8-97349767-1 / 8973497671) for ISUZU NPR and NQR trucks equipped with 4HF1, 4HE1T, 4HG1T, and 4HK1 diesel engines. This sensor measures wheel rotational speed and transmits the signal to the ABS control module, enabling anti-lock braking, traction control, and stability functions.

The wheel speed sensor monitors a toothed ring (tone ring) rotating with the wheel hub. As the teeth pass the sensor, they generate a variable reluctance (passive) or Hall-effect (active) signal proportional to wheel speed. The ABS module uses this data to detect wheel lock-up and modulate brake pressure accordingly. A failed sensor disables ABS and may trigger the warning light.

• VerifiedOEM Cross-Reference: Replaces 8-97349767-1 / 8973497671 — consistent across multiple independent supplier listings.
• VerifiedSupplier Certification: ISO/TS16949 referenced by primary supplier listing.
• VerifiedEngine Coverage: Listed for 4HF1, 4HE1T, 4HG1T, 4HK1 across multiple supplier platforms.
• VerifiedWarranty Offered: 6 months (one supplier) / 3 months (another) — confirm with seller.
• CriticalInstallation Position Conflict: One supplier lists this sensor as Front Right (passenger side on LHD). Another supplier lists the same OEM number as Rear Wheel. Confirm position on your vehicle before ordering.
• Data GapTechnical Data: No resistance values, output voltage specifications, or bench test data (temperature range, vibration resistance) was found in available search results. Request supplier test report if critical.

• ABS warning light illuminated on dashboard
• ABS system disabled (no anti-lock function during hard braking)
• Erratic or intermittent speedometer readings (if sensor shares signal with speedometer)
• Traction control or stability control warning lights active
• Diagnostic trouble code (DTC) indicating wheel speed sensor circuit fault for the affected corner

1. Disconnect battery negative terminal.
2. Raise and support vehicle; remove the wheel at the affected corner.
3. Locate the ABS sensor on the hub/knuckle assembly. Disconnect the electrical connector.
4. Remove the sensor mounting bolt (typically 8–10 mm head). Carefully extract the sensor — avoid damaging the tone ring.
5. Clean the mounting surface and inspect the tone ring for damage or debris.
6. Install new sensor; torque mounting bolt to OEM specification (confirm exact value in manual — typically low torque, 8–12 N·m range for plastic-bodied sensors).
7. Reconnect electrical connector; secure harness routing away from moving components.
8. Reinstall wheel; lower vehicle.
9. Clear ABS fault codes with a diagnostic scanner. Test-drive and verify ABS warning light remains off.

• Inspect sensor harness and connector for corrosion during brake service intervals.
• Clean tone ring and sensor face if metallic debris accumulation is suspected.
• Replace if ABS fault code indicates sensor circuit failure and wiring checks are normal.

• Neutral carton standard; color box or customer-branded packaging available.
• Suitable for: repair workshops, fleet maintenance, spare parts distributors.
