Detroit DD13, DD15 Temp Sensor 2014-2024: OEM A6805401917

Exhaust Temperature Monitoring for Detroit DD13 & DD15 Engines (2014–2024)

What is it?
The Detroit DD13 / DD15 Temperature Sensor, identified by OEM A6805401917, is a monitoring component used in engines produced between 2014 and 2024. This sensor is installed within the exhaust system—often at key points such as the DOC or SCR sections—where it measures exhaust gas temperature. The sensor converts these readings into signals that are sent to the engine control module (ECM), allowing the system to track thermal conditions in real time.

Why choose this Temperature Sensor?
Temperature data is essential for managing emissions systems and protecting engine components. The OEM A6805401917 sensor is designed for Detroit DD13 and DD15 platforms, helping ensure proper communication between the exhaust system and the ECM.

The ECM uses temperature input to regulate processes such as regeneration cycles, DEF dosing, and overall aftertreatment operation. If the sensor provides incorrect readings or fails, it can lead to improper system responses, warning alerts, or inefficient emissions control. Maintaining a properly functioning sensor helps keep the system balanced and operating as intended.

Key Benefits
✅ OEM-matched temperature sensor for Detroit DD13 and DD15 engines
✅ Monitors exhaust gas temperature at critical system points
✅ Sends real-time data to the ECM for system adjustments
✅ Supports proper regeneration and aftertreatment operation
✅ Direct-fit design for straightforward installation

Applications
This temperature sensor is used on Detroit DD13 and DD15 diesel engines manufactured from 2014 through 2024. These engines are commonly found in heavy-duty trucks and commercial vehicles equipped with advanced aftertreatment systems.

Installation Notes
Allow the exhaust system to cool completely before beginning service. Disconnect the electrical connector and remove the existing sensor from its mounting location. Inspect the wiring and surrounding area for soot buildup or damage. Install the replacement sensor using proper torque specifications, reconnect the harness, and verify accurate temperature readings using diagnostic tools.

Final Thoughts
Monitoring exhaust temperature is critical for maintaining proper emissions system performance. The Detroit DD13 / DD15 Temperature Sensor (OEM A6805401917) provides the data needed for the ECM to manage aftertreatment processes, helping support consistent operation and dependable system response.
