This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble reading how much gas is in the tank. It's like when your video game controller can't tell how many lives you have left.
The P1407 code indicates a problem with the signal from the fuel level sensor to the vehicle's powertrain control module (PCM).
The fuel level sensor sends a signal to the PCM to indicate the amount of fuel in the tank. A P1407 code is set when the PCM detects an unexpected signal from the fuel level sensor, which may be due to an incorrect reading or a malfunction.
• Inaccurate fuel gauge reading
• Check engine light illuminated
• Erratic fuel level display
• Faulty fuel level sensor
• Damaged wiring or connectors
• PCM malfunction
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Check for other codes related to the fuel system.
• Inspect the fuel level sensor and its wiring for damage.
• Test the fuel level sensor output with a multimeter.
• Replace the fuel level sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford Focus
• Chevrolet Malibu
• Toyota Camry
• Regularly check fuel level sensor connections.
• Avoid running the vehicle on low fuel frequently.
• Schedule routine maintenance checks.
Sensor Issue
• Keep track of fuel fill-ups manually until fixed.
• Avoid long trips until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on fuel system components.
This code has been reported more frequently in vehicles with high mileage or those operating in harsh conditions.
Moderate – While the vehicle may still operate, inaccurate fuel readings can lead to unexpected stalls.
Ignoring this issue may lead to running out of fuel unexpectedly, which can be dangerous.
• Vehicle at operating temperature
• Fuel level sensor connected
The fuel level sensor is typically located inside the fuel tank, attached to the fuel pump module.
Q: Can I drive with a P1407 code?
A: Yes, but be cautious as the fuel gauge may not be accurate.
Q: How do I reset the P1407 code?
A: Fix the underlying issue, then use an OBD-II scanner to clear the code.
