What impact does the SCR fault light have on the vehicle?

[SanAshley]

SCR light on will affect the engine's power reduction, and in severe cases, if not dealt with immediately, it can also lead to pump burnout. Here is some information about the SCR fault light: 1. Function: SCR refers to the Selective Catalytic Reduction system, which functions similarly to the three-way catalyst in gasoline vehicles. It uses catalysts in the traditional muffler while also requiring a urea supply system and an injection control system. It is generally used to treat NOx in diesel engines. Simply put, it processes exhaust gases. 2. Fault impact: The SCR light on indicates a fault in the Selective Catalytic Reduction system, which requires immediate inspection and repair. There are many reasons that can cause this fault, but the most critical ones are sensor damage, loose sensor connectors, short circuits, and related wiring harness issues.
