Detroit DD13, DD15 Temp Sensor 2014-2024: OEM A6805402117
Exhaust Heat Monitoring for Detroit DD13 & DD15 Engines (2014–2024)
What is it?
The Detroit DD13 / DD15 Temperature Sensor, identified by OEM A6805402117, is an exhaust monitoring component designed for engines produced between 2014 and 2024. This sensor is installed at key points within the aftertreatment system—such as the DOC inlet or outlet—where it measures exhaust gas temperature. The sensor converts heat readings into electrical signals and sends them to the engine control module (ECM) for real-time system monitoring.
Why choose this Temperature Sensor?
Exhaust temperature data is critical for maintaining proper aftertreatment function. The OEM A6805402117 sensor is designed for Detroit DD13 and DD15 platforms, helping ensure accurate thermal readings and consistent communication with the ECM.
The ECM uses this data to regulate processes such as regeneration cycles, DEF dosing, and overall emissions system coordination. If the sensor becomes inaccurate or fails, it can lead to incorrect system adjustments, warning alerts, or inefficient emissions control. Maintaining a properly functioning sensor helps keep exhaust conditions balanced and system performance stable.
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 aftertreatment operation and regeneration cycles
✅ 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 to manage emissions output.
Installation Notes
Allow the exhaust system to cool completely before beginning service. Disconnect the electrical connector and remove the existing sensor from its mounting point. 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 readings using diagnostic tools.
Final Thoughts
Maintaining proper exhaust temperature monitoring is essential for keeping emissions systems operating efficiently. The Detroit DD13 / DD15 Temperature Sensor (OEM A6805402117) provides the data needed for the ECM to manage aftertreatment processes, helping support consistent system operation and dependable emissions control.
