EGR (Exhaust Gas Recirculation) is one of the On-Board Diagnostics (OBD-II) systems related to emission. The EGR system is a pivotal element in reducing harmful emissions, making the engine run better, and improving fuel efficiency. Let’s learn further about the EGR system and how it actually works in more depth. Purpose of EGR System The main goal of the EGR system is to cut down on the amount of Nitrogen oxides(NOx) that comes out of the engine. NOx is a dangerous pollutant that makes smog and makes it hard to breathe. By sending some of … Read more

The Catalyst Monitor is a key part of the On-Board Diagnostics II (OBD-II) system. This component would ensure that vehicles meet national and/or regional emissions standards. Its job is to check and monitor how well your catalytic converter is working and make sure the emission control system is working right. We’d discuss the Catalyst Monitor’s purpose, its parts, how it works, diagnostic trouble codes(DTCs), and how important it is to keep this system well-maintained below.  Purpose of Catalyst Monitor  The main job of the Catalyst Monitor is to check how well the catalytic converter, the … Read more

An OBD2 Readiness monitor is a self-diagnostic emission monitoring system in a vehicle having a standard OBD2 system (SAE J1979). The Readiness monitor checks whether the emissions control systems (EGR, EVAP, etc) are working correctly. Most modern cars have the Readiness monitor look over up to 11 emission tests to make sure the car’s harmful emission levels are kept low. (as seen in the image below) Most Countries (i.e The United States, Australia, etc) require an annual or biannual vehicle emission inspection for the car to be legally driven on the roads, hence, it is … Read more
