Code P0453 1997 Ford F150 Description

The P0453 diagnostic trouble code (DTC) in a 1997 Ford F150 indicates that the fuel tank pressure sensor circuit is detecting a high voltage signal. This sensor is responsible for monitoring the pressure inside the fuel tank and sending this information to the vehicle's engine control module (ECM). When the voltage detected by the sensor exceeds the specified threshold, the ECM triggers the P0453 code.
