P2481 Ford Code - Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 5

Quick Answer

The P2481 code for Ford vehicles specifically refers to the Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 5. Common causes include Faulty Exhaust Gas Temperature Sensor: The sensor itself may be malfunctioning, sending incorrect signals to the ECM, Wiring Issues: Damage or corrosion in the wiring connecting the sensor to the ECM can disrupt the signal transmission, ECM Malfunction: The ECM may be at fault, not properly interpreting the signals from the sensor. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
