Laymans terms

This code means that the computer in your car thinks the sensor that measures the temperature in the fuel tank is giving a reading that doesn't make sense.

Explanation

The vehicle's computer has detected an implausible signal from the fuel tank pressure/temperature sensor, indicating that the temperature reading is outside expected parameters.

Technical description

P11E4 is triggered when the Engine Control Module (ECM) receives a signal from the fuel tank pressure/temperature sensor that is outside the expected range. This could indicate a faulty sensor, wiring issues, or an ECM problem.

Symptoms

• Check Engine Light is on

• Possible fuel odor

• Poor fuel economy

Common Causes

• Faulty fuel tank pressure/temperature sensor

• Wiring issues or poor electrical connections

• Faulty Engine Control Module (ECM)
