Detroit DD13, DD15 Temp Sensor 2014-2024: OEM A6805401317
Thermal Monitoring Control for Detroit DD13 & DD15 Engines (2014–2024)
What is it?
The Detroit DD13 / DD15 Temperature Sensor, identified by OEM A6805401317, is an exhaust monitoring component designed for engines produced between 2014 and 2024. This sensor is positioned within the aftertreatment system—often near the Diesel Oxidation Catalyst (DOC)—where it measures exhaust gas temperature and converts it into signals sent to the engine control module (ECM). These readings allow the system to track thermal conditions during operation.
Why choose this Temperature Sensor?
Temperature feedback is essential for maintaining proper emissions system function. The OEM A6805401317 sensor is designed for Detroit DD13 and DD15 platforms, helping ensure accurate readings and consistent communication with the ECM.
The ECM uses this data to regulate key processes such as regeneration cycles, exhaust flow management, and overall aftertreatment coordination. If the sensor becomes inaccurate or fails, it can lead to incorrect system adjustments, warning alerts, or inefficient emissions control. Keeping a properly functioning sensor helps maintain stable system performance and proper exhaust treatment.
Key Benefits
✅ OEM-matched temperature sensor for Detroit DD13 and DD15 engines
✅ Monitors exhaust gas temperature at critical system locations
✅ 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 for emissions control.
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 readings using diagnostic tools.
Final Thoughts
Accurate exhaust temperature monitoring is essential for keeping emissions systems operating as intended. The Detroit DD13 / DD15 Temperature Sensor (OEM A6805401317) provides the input needed for proper system control, helping maintain consistent aftertreatment performance and dependable engine operation.
