P2066 Severity
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
The Fuel Level Sensor tells the engine control module (PCM) how much fuel is in the fuel tank. When the PCM detects an irrational signal from the fuel level sensor, it will set code P2066.The Fuel Level Sensor may be part of the fuel pump.
