This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the amount of gas in the tank doesn't match how much gas the car is using. It's like if you ate a lot of cookies, but the cookie jar still looked full.
The car's computer monitors fuel levels and consumption to ensure they correlate correctly. If the readings don't match expected values, it triggers this code.
The P144B code is set when the Powertrain Control Module (PCM) detects a discrepancy between the fuel level sensor readings and the calculated fuel consumption data. This could indicate an issue with the fuel level sensor, fuel consumption calculations, or related wiring and connections.
• Check Engine Light is on
• Inaccurate fuel gauge readings
• Possible poor fuel economy
• Faulty fuel level sensor
• Issues with the fuel gauge
• Wiring or connection problems

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check fuel system components
• Ensure proper maintenance of fuel sensors
• Avoid running the vehicle on low fuel frequently
Sensor Issue
• Monitor fuel levels closely
• Address the issue promptly to avoid fuel system problems
Check with your vehicle manufacturer for warranty coverage on fuel system components.
This code has been reported in vehicles with aging fuel sensors or after fuel system repairs.
Moderate – It should be addressed soon to ensure accurate fuel readings and avoid potential fuel system issues.
Driving with inaccurate fuel readings can lead to unexpected vehicle shutdowns. Ensure repairs are done by a qualified technician.
• Vehicle at operating temperature
• Consistent driving conditions
The fuel level sensor is typically located inside the fuel tank, attached to the fuel pump module.
Q: Can I drive with a P144B code?
A: While the car may still run, it's not recommended to ignore this code as it can lead to inaccurate fuel readings.
Q: How do I reset the P144B code?
A: After repairs, the code can be reset using an OBD-II scanner. However, ensure the issue is fixed to prevent the code from returning.
