Instrucciones de reparación
NOTA: Los vehículos equipados con motores que cumplen las emisiones US2010 y posteriores tienen dos sensores
de NOx, uno que mide el nivel de NOx antes de que el escape ingrese a la unidad de Reducción catalítica selectiva
(SCR) y otro que mide el nivel de NOx después de que el escape sale de SCR. Este procedimiento es para ambas
ubicaciones del módulo de control y sensor de NOx.
