Question

How do you repair a P2103 for my 2007 Nissan Altima 4 Cyl? The battery is dead I can recharge and the next morning it is dead again.

Answer 1

The P2103 code is for the Throttle Control Motor Relay and may not be related to the battery problem. The code may come up because the battery is weak. Something else is probably draining the battery. Common causes are aftermarket products, radios, and amplifiers.
