Laymans terms

Your car has a sensor that checks the pressure in the fuel tank. This sensor is stuck and not working properly.

Explanation

The fuel tank pressure/temperature sensor is responsible for monitoring the pressure inside the fuel tank. When the sensor signal is stuck, it means the sensor is not sending the correct information to the car's computer.

Technical description

The P119F code indicates that the fuel tank pressure/temperature sensor is not providing a variable signal to the engine control module (ECM). This could be due to a mechanical failure of the sensor or an electrical issue such as a short or open circuit.

Symptoms

• Check Engine Light is on

• Possible fuel smell

• Poor fuel economy

Common Causes

• Faulty fuel tank pressure/temperature sensor

• Wiring issues such as a short or open circuit

• Connector problems at the sensor
