Nissan Sentra B15 turns off and does not respond to accelerator pedal

Hello, good morning, a Nissan Sentra B15 QG18 has arrived with a cable accelerator pedal of the year 2000, check light is on when I start it at 2 seconds, it goes out if I leave the battery disconnected for a long time when it starts it snap well but it does not live the acceleration as I should turn it off and I do not start again, I do not start the Master. Change the trothle sensor since it had one of the connectors bad some suggestion to see how I solve .. thanks and greetings
