P0203Injector Circuit/Open - Cylinder 3

The engine computer detected an electrical fault, such as an open circuit, in the control circuit for the fuel injector on cylinder 3. It is not seeing the expected electrical response from that injector. This usually means cylinder 3 is not being fueled correctly, which commonly causes a misfire on that cylinder.

Ամենատարածված պատճառներն են՝ Loose, corroded, or damaged injector connector at cylinder 3, Open or shorted wiring to the cylinder 3 injector, Failed cylinder 3 fuel injector, Poor power or ground feed to the injector, Faulty injector driver circuit in the ECM (less common)։

Սովորաբար անվտանգ է կարճ տարածությունների վրա վարել, սակայն շուտով ստուգել տվեք։

Inspect the connector and wiring at the cylinder 3 injector first, then test the injector itself. Because a misfire can harm the catalytic converter, keep driving to a minimum and get it repaired soon.
