The ZTech Volvo D13 Temperature Sensor (20513340 / 21531072) monitors both coolant and oil temperatures in the D13 engine, providing dual temperature inputs to the engine management system for thermal protection. Accurate temperature monitoring prevents catastrophic overheating damage — the ECM triggers warning systems and can perform protective shutdowns based on these readings. ZTech sensors are manufactured to OEM calibration standards for reliable temperature measurement in Volvo VNL trucks.

Q: Which trucks does this temperature sensor fit?
A: Fits Volvo VNL trucks with D13 engines. Replaces OEM part numbers 20513340 and 21531072.

Q: What fault codes does a failing temperature sensor trigger?
A: Common codes include SPN 110 (engine coolant temperature) and SPN 175 (engine oil temperature) faults in Volvo VCADS.

Q: What happens if a temperature sensor fails?
A: A failed sensor can cause false overheating warnings (unnecessary shutdowns) or fail to detect actual overheating (engine damage).

Q: Is this OEM or aftermarket?
A: ZTech is a European aftermarket brand manufacturing sensors calibrated to Volvo D13 OEM temperature specifications.

Q: What is included with this sensor?
A: Includes the complete dual coolant/oil temperature sensor assembly with connector, ready for plug-and-play installation.
