Dear customer, this is an error code that tells us that there are no problems with the fuel pressure, this can be due to various inconveniences such as problems at the fuel regulation due to damage to the regulator, problems at the pump, you may be having one of the injectors working directly like your 2005 model, it is normal for these types of problems to occur and ideally, when there are these error codes, a check and maintenance to the injection system is carried out as complete as possible. It consist of cleaning injectors, replacing the pump, checking the regulator, etc.
