Could a map or Maf sensor put car into limp mode?

Yes, a malfunctioning mass airflow (MAF) sensor or manifold absolute pressure (MAP) sensor can indeed cause a car to enter limp mode. These sensors play a critical role in the engine management system by providing essential data for fuel and air mixture calculations. If either sensor fails or sends incorrect readings, the engine control unit (ECU) may trigger limp mode to protect the engine from potential damage, limiting performance and speed. Regular diagnostics can help identify and resolve issues with these sensors.
