Try resetting the ECU (ELECTRONIC CONTROL UNIT) sometimes the ECU needs to be reset if an error occurs. how can the fuse unplug ECU / EFI look at the fuse box. remove and let stand about 3-5mn and then reinstall and start the engine let it live for 5-15 minutes and take your vehicle to the road so that the ECU record your driving character. or by unplugging the power to the battery, but it will reset all electrical components including the radio (not recommended).
