This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the fuel gauge is stuck and not showing the correct amount of gas in the tank.
The fuel level sensor is responsible for sending the fuel level information to the vehicle's computer. If the signal is stuck, it means the sensor is not changing its output as the fuel level changes.
The P142D code indicates that the fuel level sensor is not providing a variable signal to the engine control module (ECM) as expected. This could be due to a mechanical issue with the sensor or an electrical problem in the circuit.
• Fuel gauge stuck at a certain level
• Check Engine Light is on
• Inaccurate fuel readings
• Faulty fuel level sensor
• Wiring issues in the fuel level sensor circuit
• Malfunctioning instrument cluster
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Inspect the wiring and connectors for the fuel level sensor.
• Test the fuel level sensor for proper operation.
• Check the instrument cluster for faults.
• Replace the fuel level sensor if faulty.
• Repair or replace damaged wiring.
• Recalibrate or replace the instrument cluster if necessary.
• Multimeter
• OBD-II scanner
• Screwdriver set

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regularly check the fuel gauge for accuracy.
• Inspect wiring for signs of wear or damage.
• Keep the fuel tank clean to prevent sensor issues.
Sensor Issue
• Monitor fuel level manually until the issue is resolved.
• Avoid letting the fuel level drop too low.
Check with your vehicle manufacturer; fuel system components may be covered under warranty.
This code has been associated with vehicles that have experienced wiring issues or sensor failures in the fuel system.
Moderate – It is important to have an accurate fuel reading, but it is not an immediate safety concern.
Driving with an inaccurate fuel gauge can lead to running out of fuel unexpectedly, which may be dangerous.
• Vehicle parked on a level surface
• Ignition in the ON position
The fuel level sensor is typically located inside the fuel tank, attached to the fuel pump assembly.
Q: Can I drive with a P142D code?
A: Yes, but it's important to monitor your fuel level manually to avoid running out of gas.
Q: How do I know if my fuel level sensor is bad?
A: If your fuel gauge is stuck or showing incorrect readings, the sensor may be faulty.
