Code P1115 2001 Ford F150 Description

The P1115 code for a 2001 Ford F150 indicates a problem with the Intake Air Temperature Sensor 2 Circuit being too high. This sensor is responsible for monitoring the temperature of the air entering the engine. When the sensor detects a high voltage signal, it triggers the P1115 code. This issue can have a significant impact on the vehicle's performance as the engine control module relies on accurate temperature readings to adjust the air-fuel mixture for optimal combustion. If left unaddressed, it can lead to decreased fuel efficiency, rough idling, poor acceleration, and potential engine damage.
