VG1500090061 Sensor Euro3 Key To Boosting Engine's Performance

Function, Specifications, Materials, and Key Parameters of VG1500090061 Coolant Temperature Sensor

1. Function

• Coolant Temperature Monitoring: The VG1500090061 sensor measures the temperature of the engine coolant, providing real-time data to the engine control unit (ECU) for precise fuel management, ignition timing, and fan control.

• Engine Protection: By monitoring coolant temperature, it helps prevent overheating and ensures optimal engine performance under varying loads and environmental conditions.

• Diagnostic Support: Provides input for onboard diagnostics (OBD) systems to detect coolant-related issues (e.g., overheating, thermostat failure).

2. Specifications

• Part Number: VG1500090061

• English Name: Coolant Temperature Sensor (also referred to as "ECT Sensor" or "Engine Coolant Temperature Transducer")

• Installation Location:

• Engine System: Integrated into the cooling system of heavy-duty trucks (e.g., Sinotruk WD615 series engines).

• Common Positions: Near the thermostat housing, cylinder head, or radiator outlet.

• Compatibility: Designed for Euro III (or earlier) emission standard engines, commonly used in Sinotruk HOWO A7 and other commercial vehicles.

3. Materials

• Sensor Housing:

• Stainless Steel or Brass: Provides corrosion resistance and durability in harsh engine environments.

• Thermal Element:

• NTC (Negative Temperature Coefficient) Thermistor: A semiconductor-based sensor whose resistance decreases as temperature increases.

• Electrical Connectors:

• Plastic or Rubber-Coated Terminals: Ensure waterproofing and vibration resistance.

4. Key Parameters

• Temperature Range:

• Operating Range: -40°C to +150°C (or -40°F to +302°F).

• Accuracy: ±1–2% over the operating range.

• Electrical Characteristics:

• Resistance at 25°C (77°F): Typically 2.2–2.5 kΩ (varies by manufacturer).

• Output Signal: Analog voltage (0–5V) or resistance-based signal proportional to temperature.

• Thread Size:

• M12 x 1.5 or M16 x 1.5: Common thread sizes for mounting in the engine block or cooling system.

• Response Time:

• < 5 Seconds: Rapid temperature detection to support real-time engine adjustments.

• IP Rating:

• IP67 or Higher: Dustproof and waterproof for automotive applications.

Additional Notes

• OEM vs. Aftermarket: The VG1500090061 is available as an original Sinotruk part or aftermarket replacement, with slight variations in specifications.

• Maintenance: Requires periodic inspection for corrosion or damage, with replacement recommended if resistance values deviate from specifications.

• Calibration: Factory-calibrated for specific temperature ranges; recalibration is not typically user-serviceable.

The VG1500090061 coolant temperature sensor is critical for engine reliability and efficiency, ensuring optimal performance in heavy-duty commercial vehicles.
