Detroit Diesel Differential Pressure Sensors
Detroit Diesel differential pressure sensors measure exhaust pressure before and after the DPF to monitor soot load and regeneration efficiency. Accurate readings are critical for proper aftertreatment operation and preventing engine derates. At Advanced Truck Parts, we supply Detroit Diesel pressure sensors designed for reliable performance in heavy-duty engines.

Detroit Diesel Differential Pressure Sensors in DPF Systems
Differential pressure sensors are a key component of the diesel particulate filter (DPF) system. They measure the pressure difference across the filter to determine soot accumulation and trigger regeneration cycles when needed.
These sensors help the ECM:
- Monitor DPF soot load in real time
- Control active and passive regeneration cycles
- Prevent excessive exhaust restriction
- Maintain proper aftertreatment efficiency
Accurate pressure readings are essential for preventing DPF clogging and maintaining engine performance.
Common Detroit Diesel Engine Applications
Detroit Diesel differential pressure sensors are used in engines equipped with DPF and SCR aftertreatment systems.
- Detroit Diesel DD13 engines
- Detroit Diesel DD15 engines
- Detroit Diesel DD16 engines
- Freightliner Cascadia and Western Star trucks
Sensor configurations may vary depending on emissions generation and exhaust system design.
Common Failure Symptoms
- DPF or aftertreatment fault codes
- Frequent or failed regeneration cycles
- Engine derate conditions
- Incorrect soot load readings
- Check engine light related to exhaust system
Failures may result from sensor contamination, clogged pressure lines, electrical issues, or internal sensor malfunction.
Installation & System Considerations
When replacing a differential pressure sensor, it’s important to inspect related components in the exhaust system.
- Check pressure tubes for blockage or soot buildup
- Inspect DPF condition and ash load
- Verify wiring harness and connectors
- Ensure proper routing of pressure lines
Addressing these areas helps ensure accurate readings and prevents repeat sensor failures.
Verify Fitment Before You Buy
Differential pressure sensors are specific to engine model and emissions configuration. To confirm compatibility before ordering, provide:
- Engine serial number
- Truck year / make / model
- Current sensor part number
- Photos of the sensor and pressure lines if available
This ensures the correct Detroit Diesel sensor is selected for your application.
