Code P20C1 Ford Description
The P20C1 Ford code indicates a problem with the Reductant Heater 'C' control circuit in the vehicle's Selective Catalytic Reduction (SCR) system. The SCR system is responsible for reducing harmful emissions by injecting a urea-based solution, known as diesel exhaust fluid (DEF), into the exhaust stream. The Reductant Heater 'C' is a component that helps heat the DEF to optimize its chemical reactions and reduce emissions effectively.
