Engine Speed Sensor 8-98019024-0 8980190240 For ISUZU ELF 4HK1 Diesel Truck

The Engine Speed Revolution Sensor (OEM Numbers: 8-98019024-0 / 8980190240) is a premium-quality, direct replacement engine management sensor designed specifically for ISUZU ELF series trucks equipped with 4HK1 diesel engines.

This sensor - also known as an engine speed sensor, revolution sensor, or crankshaft position sensor - monitors the rotational speed and position of the engine crankshaft or flywheel. It converts this information into an electrical pulse signal that is transmitted to the engine control unit (ECU). The ECU uses this signal to control fuel injection timing, injection quantity, idle speed, exhaust gas recirculation (EGR), and other critical engine management functions. It also provides the signal for the dashboard tachometer.

• OE Quality: Manufactured to strict ISUZU dimensional and electrical specifications for perfect fit and function.
• Accurate Speed Signal: Precision sensing element provides reliable, consistent engine speed signal to ECU and tachometer.
• Durable Construction: Robust housing resists vibration, temperature extremes, and under-hood contaminants.
• Sealed Connector: Prevents moisture and dust intrusion, ensuring long-term electrical reliability.
• Restores Engine Performance: Eliminates hard starting, rough idle, power loss, and tachometer malfunction caused by a faulty sensor.
• Improves Fuel Efficiency: Correct engine speed signal ensures proper injection timing and combustion efficiency.
• Direct Replacement: Matches OE sensor dimensions, mounting configuration, and electrical connector.
• Long Service Life: Engineered for heavy-duty commercial diesel engine 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 engine management without costly diagnostics.

This engine speed sensor is specifically designed for ISUZU medium-duty trucks and commercial vehicles. Common applications include:

• ISUZU ELF (Medium-Duty Trucks)
• ISUZU FR, FS, FT series (as applicable)
• ISUZU 4HK1 Engine Specifications:
  • 4-Cylinder, Inline Turbo Diesel
  • Displacement: 5.2L
  • Application: Medium-duty trucks and commercial vehicles

Also compatible with various ISUZU models using the 4HK1 engine and the same engine speed sensor configuration.

Professional mechanic or auto electrician installation recommended:

1. Disconnect battery - Always disconnect the negative terminal before working on electrical components.
2. Locate the engine speed sensor - Typically mounted on the flywheel housing, timing cover, or cylinder block.
3. Disconnect electrical connector - Carefully unplug the wire harness connector from the old sensor.
4. Remove the old sensor - Unscrew or unbolt the old sensor from its mounting location.
5. Clean the mounting area - Remove dirt, debris, or metal particles from the sensor mounting hole and trigger wheel/flywheel teeth.
6. Inspect trigger wheel/flywheel - Check for damaged or missing teeth on the tone ring or flywheel.
7. Install new sensor - Thread or bolt the new sensor into position; ensure proper seating.
8. Adjust air gap - If applicable, set the air gap between sensor tip and trigger wheel per specification.
9. Reconnect electrical connector - Plug the wire harness securely into the new sensor; apply dielectric grease.
10. Reconnect battery - Reconnect the negative terminal.
11. Test operation - Start the engine and verify proper tachometer operation, smooth idle, and no warning lights.
12. Clear codes - Use a diagnostic scanner to clear any related trouble codes.
