Product Overview
A warning light, reduced-power mode, failed regeneration, or implausible exhaust-pressure reading may lead a technician to this sensor after the pressure hoses, ports, wiring, and exhaust system are checked. A blocked hose can mimic a failed sensor, so scan data and physical inspection matter.
The sensor compares pressure across the connected exhaust circuit and reports that signal to the control module. It does not clean a blocked filter or repair split hoses, carbon-packed ports, damaged wiring, or an exhaust leak.
Compare both hose ports, electrical connector, mounting bracket requirements, calibration reference, engine, year, and original number. Some replacement listings do not include the mounting bracket.
Key Features & Performance
- Dual pressure ports for the matching exhaust hoses
- Vehicle-style electrical connector for listed references
- Supports accurate exhaust-pressure feedback after proper diagnosis
- Replacement sensor body; bracket inclusion must be confirmed from photos

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above. Model year, production date, serial number, engine or equipment specification, installed options, and previous repairs can change fitment. Match the original part, reference number, dimensions, connectors, mounting points, and product photos before purchase.
Frequently Asked Questions
Q: Can this fix a DPF warning light? A: Only if testing identifies the sensor as the fault. A restricted filter, blocked hose, exhaust leak, wiring fault, or failed regeneration can set similar codes.
Q: Does it include the mounting bracket? A: Do not assume so; compare the listing photos and reuse the original bracket if required.
Q: Can I swap the two pressure hoses? A: No. Reversed hoses produce incorrect readings. Label them before removal.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
