Our certified mechanics come to you · 12-month, 12,000-mile warranty
P2067 is a diagnostic trouble code (DTC) for "Fuel Level Sensor B Circuit Low". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
Fuel Level Sensor B Circuit Low
The Engine Control Module (ECM) utilizes a sensor either built into the fuel pump, or into the fuel tank, which communicates to the ECM the level of the fuel. The P2067 code will set if the fuel level becomes low or erratic. This code will also set if the sensor becomes non-communicative. The job of this sensor is to simply tell the ECM the level of the fuel.
The fuel level sensor communicates the level of fuel to the ECM by sending a voltage signal; the lower the gasoline level, the lower the voltage signal. However, the voltage may become spontaneous if the fuel level sensor is faulty, then a code P2067 will likely set. In most modern vehicles, there are two fuel sensors, one on each side of the gas tank (A,B). If there is too much variation detected in the side-by-side comparison of the sensors, a code P2067 may set. For example sensor, if Sensor A says 80% full while Sensor B says 20% full, P2067 will set because the ECM sees this as an abnormality.
Tests the fuel level sensor with a multimeter to ensure it has a proper ground, adequate voltage supply, and voltage feedback
Checks the fuel pressure
Uses a multimeter to measure the resistance of the fuel level sensor, then comparing it to specifications
Inspects the ECM for opens, shorts, frayed wiring, corrosion or broken connections
Inspects the circuit of the fuel level sensor for an open or shorted condition
Inspects the instrument cluster for faults such as broken solder contact points
This code commonly pertains to newer vehicles ranging from 2008-present. If you have this code it is likely that the manufacturer will repair it under warranty. It is suggested to check with your manufacturer to verify if your vehicle qualifies for warranty repair.
This particular code is not harmful or damaging to the vehicle, although with a Check Engine Light, you can not legally pass inspection. If you have a newer vehicle (2008- present) and trouble code P2067, it may be under warranty. To help minimize the chances of missing the opportunity for a warranty repair, it is suggested that you find out your warranty package as soon as this code is discovered.
The most likely fix for this particular trouble code is the replacement of the fuel pump, or, if you’re lucky, the fuel level sensor itself. In most cases, the entire pump will have to be replaced, even if it is just the fuel level sensor that as faulted, because in most vehicles, the fuel level sensor and fuel pump are built as one.
