Cummins QSB 6.7L, B6.7 Temp Sensor 2013-2018: OEM 5461627
Keep Engine Temperatures in Check for Cummins QSB 6.7L & B6.7 (2013–2018)
What is it?
The Cummins QSB 6.7L / B6.7 Temperature Sensor, listed under OEM 5461627, is a monitoring sensor used on Cummins diesel engines built from 2013 through 2018. Its job is to detect temperature at a designated system location (commonly within exhaust or cooling-related circuits) and send that information to the engine control unit. That data helps the engine and emissions systems make the right adjustments during operation.
Why choose this Temp Sensor?
This sensor is designed to match Cummins specifications for both the QSB 6.7L and B6.7 platforms. When temperature sensors become inaccurate or fail, the engine may receive incorrect heat readings, which can lead to system fault codes, inconsistent engine behavior, or improper emissions-related adjustments. Installing the correct OEM-specified sensor supports stable monitoring and helps keep engine management decisions consistent.
Key Benefits
✅ Designed for Cummins QSB 6.7L and B6.7 engines (2013–2018)
✅ Provides dependable temperature feedback to engine electronics
✅ Helps support smoother emissions and engine management operation
✅ Direct replacement fit — no modifications required
✅ Built for harsh heat exposure and heavy-duty working environments
Applications
This temperature sensor is commonly used in a wide range of equipment powered by Cummins QSB 6.7L or B6.7 engines from 2013 to 2018. It’s often found in commercial trucks, industrial machinery, construction equipment, agricultural units, and generator applications where accurate temperature tracking is necessary for reliable engine operation.
Installation Notes
Let the engine and exhaust system cool fully before starting service. Disconnect the sensor’s electrical connector, remove the existing unit, and inspect the sensor port along with the wiring harness for buildup or damage. Install the replacement sensor and torque it to specification, then reconnect the harness. After installation, clear fault codes and verify proper temperature readings using diagnostic tools.
Final Thoughts
If your equipment is throwing temperature-related codes or showing inconsistent engine/emissions behavior, replacing the sensor with the correct OEM unit can help restore accurate thermal feedback. The Cummins QSB 6.7L / B6.7 Temp Sensor (OEM 5461627) plays an important role in maintaining stable monitoring and dependable system operation.
