Hi I have a clio 182 54 plate which has this following code currently the engine management light is on as well as traction control light and service light now when I ran dinosics on my £ 10 reader in came up with 0 2 sensor fault and injector fault I have replaced injector and misfire has gone and cleared 02 fault code and injector fault just left speed sensor now am I right in thinking that a 182 gets it speed from abs sensors and if one of them is playing up it sends a fault code to ecu which puts on management light I havnt cleaned any sensors or checked them yet is this best to do that also all my dials work as they should I don't know about speedo as car has no mot or tax so is it worth just raking it down Road opposite just to check speedo any help would be greatly appreciated
