DEF Sensor Simulator – Arduino DUE (Original Build)
Assembling a DEF Sensor Simulator Using an Arduino DUE with CAN Card Following is the build process for the original version of the DSS hardware and software from September 2021. This is still a valid solution and requires no soldering, however, check the Quick Build page for the currently recommended solution which is likely to be smaller and less expensive. Only basic electrical and DIY skills are required for the hardware assembly, no soldering isLearn More
DEF Sensor Simulator – Quick Build
Page last updated May 30, 2022 Since the original DSS solution published in September of 2021, the team has been busy looking at alternative hardware and software options. This page has a brief description and links to the build instructions for all the variants developed to date. The solution in the Recommended section has been deemed by the team to be the most viable current option considering factors such as price, size, parts availability, easeLearn More

DEF Sensor Simulator
Background: DEF systems in modern diesel engines are key to reducing Nitrous Oxide (NOx) emissions and protecting the environment. The DEF system is a combination of software, hardware and DEF fluid that enable this important task. Recently there has been a pandemic of failures affecting one of the elements of the DEF system called the DEF sensor. The origins of this “DEF pandemic” are not known for certain but the failures may be related toLearn More
