Vehicle Speed Sensor 8-97256525-0 8972565250 For ISUZU NKR77 4JH1T 4KH1T Truck

The Vehicle Speed Sensor (OEM Numbers: 8-97256525-0 / 8972565250) is a premium-quality, direct replacement electronic sensor designed specifically for ISUZU NKR77 series light-duty trucks equipped with 4JH1T and 4KH1T diesel engines.

Vehicle speed sensor measures transmission output speed and sends electrical signal to ECU and speedometer, ensuring accurate speed display and proper vehicle operation in ISUZU NKR77 trucks.

This precision-engineered sensor monitors the rotational speed of the transmission output shaft and converts it into an electrical pulse signal. The signal is transmitted to the engine control unit (ECU), instrument cluster, and other vehicle systems. It is essential for accurate speedometer display, odometer operation, proper transmission shift control, and various engine management functions.

• OE Quality: Manufactured to strict ISUZU dimensional and electrical specifications for perfect fit and function
• Accurate Speed Signal: Precision sensing element provides reliable, consistent speed signal to ECU and instrument cluster
• Durable Construction: Robust housing resists vibration, temperature extremes, and under-vehicle contaminants
• Sealed Connector: Prevents moisture and dust intrusion, ensuring long-term electrical reliability
• Restores Speedometer Function: Eliminates erratic, intermittent, or non-operational speed display
• Improves Drivability: Correct speed signal ensures proper transmission shift points and vehicle operation
• Direct Replacement: Matches OE sensor dimensions, thread pitch, and electrical connector
• Long Service Life: Engineered for light-duty commercial truck applications
• Essential for Diagnostics: Proper speed signal helps avoid false trouble codes and enables accurate system monitoring
• Cost-Effective Repair: Affordable replacement that restores proper vehicle speed sensing

Professional mechanic or auto electrician installation recommended:

1. Ensure vehicle is safely raised - Use appropriate jack stands or a lift to access the sensor location
2. Locate the vehicle speed sensor - Typically mounted on the transmission output shaft housing or rear differential
3. Disconnect battery - Always disconnect the negative terminal before working on electrical components
4. Disconnect electrical connector - Carefully unplug the wire harness connector from the old sensor
5. Remove the old sensor - Unscrew or unbolt the old sensor from its mounting location
6. Clean the mounting area - Remove dirt, debris, or metal particles from the sensor mounting hole and trigger wheel
7. Inspect trigger wheel - Check for damaged or missing teeth on the tone ring/trigger wheel
8. Install new sensor - Thread or bolt the new sensor into position; ensure proper seating
9. Adjust air gap - If applicable, set the air gap between sensor tip and trigger wheel per specification
10. Reconnect electrical connector - Plug the wire harness securely into the new sensor; apply dielectric grease
11. Reconnect battery - Reconnect the negative terminal
12. Test operation - Start the engine and drive the vehicle; verify speedometer operation and check for trouble codes
13. Clear codes - Use a diagnostic scanner to clear any related trouble codes

• Electrical Testing: Each sensor tested for proper signal output and resistance
• Signal Waveform Verification: Sample tested to ensure clean, consistent pulse signal
• Dimensional Inspection: Thread size, body length, and connector type verified for exact fit
• Sealing Inspection: Housing and connector checked for proper sealing against moisture and dust
• Visual Inspection: 100% checked for defects, damage, or assembly errors
• Packaged Safely: Protected and packaged to prevent damage during transit
