Restore Proper Aftertreatment Function on Your Volvo with a New Pressure Sensor
Is your Volvo diesel logging aftertreatment fault codes, going into derate, or failing to complete a DPF regeneration cycle? A faulty pressure sensor in the exhaust aftertreatment system is one of the more common causes behind those symptoms. The pressure sensor monitors the exhaust system, feeding real time data to the ECM so it can manage DPF loading and trigger regeneration at the right time. When that sensor starts reading incorrectly or stops reporting altogether, the ECM loses the information it needs to manage the aftertreatment system properly, and the result is often fault codes, failed regens, or a truck running in reduced power mode until the fault is addressed. HHP’s new 20451992 pressure sensor replaces that failing component with a quality aftermarket part built to get your Volvo back to proper aftertreatment function.
Why Replacing a Failing Pressure Sensor Quickly Matters
Aftertreatment sensors are small parts that carry a big responsibility. They are exposed to exhaust heat, vibration, and the chemical environment of a diesel aftertreatment system every hour the engine runs, and that environment wears them out over time. Replacing a failed or failing sensor quickly matters because an ECM running on bad pressure data cannot manage the DPF correctly, which can lead to plugged filters, missed regenerations, and additional repair costs on top of the original sensor failure.
Built to OEM Specifications in an ISO 9001:2015 Certified Facility
The 20451992 pressure sensor is manufactured in an ISO 9001:2015 certified facility and built with hard wearing materials designed to withstand the heat and operating conditions of a Volvo diesel aftertreatment system. Each unit is built to OEM specifications for proper fitment and function, so it installs correctly and gives the ECM accurate readings from the moment it goes in.

Frequently Asked Questions, Volvo Pressure Sensor (20451992)
What does the 20451992 pressure sensor do on a Volvo diesel?
This sensor monitors exhaust pressure in the aftertreatment system and reports that data to the ECM in real time. The ECM uses those readings to manage DPF soot loading and determine when to trigger a regeneration cycle.
What are the symptoms of a failing Volvo pressure sensor?
Common symptoms include aftertreatment or DPF related fault codes, failed or incomplete regeneration cycles, and the engine going into reduced power mode or derate while the fault is active.
Is the 20451992 pressure sensor new or remanufactured?
This is a brand new pressure sensor, not remanufactured. It is manufactured in an ISO 9001:2015 certified facility to OEM specifications for proper fit and function.
Which Volvo engines does this pressure sensor fit?
This sensor fits the Volvo ALL engine range and cross references to part numbers 20451992 and 8CL005. HHP recommends submitting your ESN or VIN at checkout so the parts team can confirm fit for your specific model year and configuration.
Does this pressure sensor have a core charge?
No. This is a new part with no core charge, so there is no deposit to pay and nothing to return after installation.
What warranty comes with the 20451992 pressure sensor?
This sensor is backed by a 1 year warranty, along with support from ASE certified technicians for questions about the order or the installation.
How fast will my pressure sensor ship?
In stock orders placed by 2 PM EST ship the same day, Monday through Friday, so your truck is not sitting any longer than it needs to be.
