Code P2053 GMC Description
The P2053 GMC code indicates a problem with the Reductant Injection Valve Circuit/Open in Bank 1 Unit 2. This code specifically relates to the selective catalytic reduction (SCR) system in diesel vehicles. The SCR system is responsible for reducing nitrogen oxides (NOx) emissions by injecting a urea-based solution, known as diesel exhaust fluid (DEF), into the exhaust stream. The reductant injection valve controls the flow of DEF into the exhaust system to facilitate the chemical reaction that converts harmful NOx emissions into nitrogen and water vapor.
