hi, yes I had already seen this page and changed the connectors. the injector is ok because even when I disconnect the cable the error appears. which does not happen when I disconnect the cable of injector 4. I checked the cables and also the insulation.. everything is ok. I will tell you more I get the error even if I disconnect the large connector of the ECU leaving only the small one connected which is power supply
