P202E: Your Car’s Fuel Injector Circuit Low – Explained
The P202E fault code is related to the reductant injection valve circuit in the Selective Catalytic Reduction (SCR) system.
It indicates that there is a range or performance issue with the circuit in Bank 1 Unit 1. This circuit is responsible for injecting a metered amount of Diesel Exhaust Fluid (DEF) into the exhaust gas stream to reduce oxides of nitrogen (NOx) emissions. The Engine Control Module (ECM) uses upstream and downstream NOx sensors to vary the amount of DEF added by varying the reductant injector duty-cycle in response to changes in engine-out NOx levels.
FAQ
If your engine light is on and you’re seeing the P202E fault code, it could be due to a faulty Reductant Fluid Injector, an open or shorted Reductant Fluid Injector harness, or a poor electrical connection in the Reductant Fluid Injector circuit.
