This summary uses the existing diagnostic information shown in full below.
The car's computer thinks the sensor that checks the gas tank's pressure and temperature is not working right because it's too cold.
The P11DC code is triggered when the vehicle's engine control module (ECM) detects a problem with the fuel tank pressure/temperature sensor, specifically indicating that the temperature is lower than expected.
The P11DC code indicates that the fuel tank pressure/temperature sensor is reporting a temperature reading that is below the expected range. This could be due to a sensor malfunction, wiring issues, or environmental factors affecting the sensor's performance.
• Check Engine Light is on
• Possible fuel smell
• Decreased fuel efficiency
• Faulty fuel tank pressure/temperature sensor
• Wiring issues or poor connections
• Environmental factors such as extreme cold
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to verify the code.
• Inspect the wiring and connections to the sensor.
• Test the sensor's resistance and voltage output.
• Replace the faulty sensor.
• Repair or replace damaged wiring or connectors.
• Ensure the sensor is properly insulated against environmental factors.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regularly inspect sensor connections.
• Avoid exposing the vehicle to extreme temperatures.
• Perform regular maintenance checks.
Sensor Issue
• Have the vehicle inspected by a professional if the Check Engine Light is on.
• Avoid driving in extremely cold conditions until the issue is resolved.
Check your vehicle's warranty; sensor issues may be covered under emissions warranty.
This code is relatively uncommon and is typically associated with vehicles operating in colder climates.
Moderate – It is important to address this issue to prevent further fuel system problems.
Operating a vehicle with a malfunctioning sensor can lead to increased emissions and may not comply with legal standards.
• Vehicle must be in a cold environment.
• Engine should be off for accurate testing.
The fuel tank pressure/temperature sensor is typically located near or on the fuel tank itself.
Q: Can I drive with a P11DC code?
A: It's best to have it checked soon, as it can affect fuel efficiency and emissions.
Q: How can I prevent this code?
A: Regular maintenance and avoiding extreme cold can help prevent this issue.
