Other issues, although very rare, can be the car components that trigger limp mode don't emit the signals to the ECU.

Fuel and Air Delivery Problems

Poor acceleration can result from an engine that's running lean (not enough fuel). Similarly, a lack of airflow can also prevent the engine from accelerating as it should. Some of the most common causes of fuel and air delivery issues include: A weak fuel pump.

Will disconnecting battery fix limp mode?

Sometimes. If the limp mode is set by the ECU, disconnecting the battery may reset the limp mode. The limp mode will most likely return as soon as you start to drive or once the engine warms up. If limp mode is set by the transmission module, disconnecting the battery won't reset the limp mode.
