Iveco 500382599 Temperature Sensor: Function, Specifications, and Industry Applications
The Iveco 500382599 Temperature Sensor is a crucial engine monitoring component designed to ensure the optimal performance, efficiency, and safety of various Iveco commercial vehicles. Found in engine and coolant systems, this sensor is responsible for continuously monitoring temperature values and relaying real-time data to the vehicle’s electronic control unit (ECU). Whether it’s protecting the engine from overheating or enabling emissions control systems to function properly, the 500382599 sensor plays a vital role in modern diesel vehicle management.
1. What is a Temperature Sensor?
A temperature sensor in an internal combustion engine measures the thermal conditions of various components—typically the engine coolant, oil, or intake air. The Iveco 500382599 sensor usually functions as a coolant temperature sensor (CTS), though it may also be configured for other thermal monitoring roles depending on the vehicle application.
The sensor allows the ECU to:
-
Adjust fuel injection timing and quantity
-
Manage the cooling fan operation
-
Control exhaust gas recirculation (EGR)
-
Optimize engine start and idle functions
-
Trigger warning lights if temperatures exceed safe limits
2. Technical Specifications of Iveco 500382599
-
Part Number: 500382599
-

3. Vehicle Compatibility and Applications
The 500382599 sensor is used across a wide range of Iveco vehicles, particularly:
-
Iveco Daily (various generations)
-
Iveco Eurocargo
-
Iveco Stralis and Trakker trucks
-
Iveco Bus and coach platforms
Its primary role in these vehicles is engine coolant monitoring, though it may also serve oil temperature or EGR temperature sensing functions.
Always verify the compatibility using the vehicle’s VIN or by consulting the official Iveco parts catalog.
4. Role in Modern Engine Management
The 500382599 temperature sensor directly affects how the ECU controls the following systems:
-
Fuel Management: Cold engines require a richer fuel mixture; this sensor informs the ECU when to adjust.
-
Cooling System Activation: Signals when the radiator fan should engage.
-
Emission Control: Ensures that components like the EGR and DPF (Diesel Particulate Filter) operate within the correct temperature range.
-
Dashboard Readings: Sends data to temperature gauges on the instrument panel.
In case of a fault or incorrect temperature reading, the ECU may enter a default mode or trigger fault codes that affect drivability.
5. Common Signs of Sensor Failure
When the Iveco 500382599 sensor malfunctions, drivers and technicians may notice:
-
Check Engine Light (CEL)
-
Poor fuel economy
-
Difficulty starting, especially when cold
-
Erratic temperature gauge behavior
-
Overheating or delayed fan activation
Faulty readings can disrupt the engine’s air-fuel ratio and lead to increased emissions, reduced performance, or even engine damage.
6. Diagnostic and Replacement Procedure
Diagnosis:
-
Use a diagnostic tool to scan for DTCs (Diagnostic Trouble Codes)
-
Measure resistance with a multimeter and compare with standard temperature-resistance curves
Replacement:
-
Allow the engine to cool completely.
-
Locate the sensor (refer to the vehicle manual).
-
Disconnect the battery and unplug the sensor’s electrical connector.
-
Use a socket wrench to remove the old sensor.
-
Apply thread sealant (if recommended) and install the new sensor.
-
Reconnect wiring and refill coolant if necessary.
Note: Always clear any error codes using a scan tool and test the system post-installation.
7. OEM vs. Aftermarket Considerations
Genuine Iveco 500382599 sensors ensure full compatibility and calibration accuracy. However, high-quality aftermarket alternatives are also available. When choosing non-OEM sensors, confirm:
-
Correct resistance curve and voltage output
-
Durable, heat-resistant materials (e.g., brass or stainless steel body)
-
ISO/TS 16949 certification for quality standards
8. Packaging, Storage, and Handling
Sensors are delicate electronic components and must be handled carefully. For best storage practices:
-
Store in original anti-static and moisture-proof packaging
-
Avoid exposure to magnetic fields or high heat
-
Do not remove protective caps until installation
Iveco 500382599 Temperature Sensor
The Iveco 500382599 Temperature Sensor is a small but critical component that ensures the efficient and safe operation of diesel engines across Iveco’s commercial vehicle lineup. From managing engine cooling to supporting emissions control systems, its role is deeply embedded in the vehicle’s overall performance strategy. Regular diagnostics and timely replacement with genuine or certified aftermarket parts help prevent engine issues and ensure operational continuity. Whether for workshop repairs or international trade, this sensor remains a high-priority item for maintaining modern commercial vehicle fleets.
