Technical Specifications: Genuine VOLVO Electronic Temperature Sensor Module 20513340Genuine VOLVO Electronic Temperature Sensor Module — Engine & Hydraulic Thermal Monitoring Solution
The Genuine VOLVO Premium Heavy‑Duty Electronic Temperature Sensor Module (Part Numbers: 20513340 / VOE 20513340 / 21531072) monitors coolant, engine oil and hydraulic fluid temperature via high‑precision NTC thermistor. It transmits resistance‑based voltage signals to V‑ECU (11381435) to control cooling fans and fuel injection timing. Replacing drifting sensors prevents engine overheating, power derating and exhaust black smoke.
Core Technical Advantages
High‑Accuracy NTC Thermistor: Excellent thermal linearity, low drift and rapid temperature response.
Corrosion‑Proof Brass Housing: High‑grade brass resists coolant, oil and hydraulic fluid corrosion with precision threads.
IP67 Sealed Vibration‑Resistant Connector: Silicone‑gasketed over‑molded plug blocks moisture, dust and high‑pressure wash damage.
EMI/RFI Noise Suppression: Internal shielding eliminates alternator and radio frequency interference.

Critical B2B Procurement & Maintenance Guidelines
B2B Procurement Strategy
Temperature sensors fail under thermal shock and chemical corrosion, causing false overheat alarms and engine power loss. Stock 20513340/21531072 for emergency repairs. Cross‑sell with water pumps, radiators and wiring harness (14597767) for cooling system overhaul.
Common Failure Symptoms
False overheat warnings and automatic engine power derating
Frozen temperature gauge or “Open Circuit” fault codes from internal wire breakage
Exhaust black smoke and high fuel consumption caused by false low‑temperature signals
Best Practice Overhaul Advisory:
Disconnect main battery and fully cool engine/coolant system before replacement to avoid scalding and voltage spikes damaging ECU. Clean mounting area, install sensor with correct torque, reconnect harness and verify temperature readings.
