Code P2067 2015 GMC Sierra Description
The primary fuel level sensor and the secondary fuel level sensor change resistance based on fuel level. The Fuel Pump Driver Control Module monitors the signal circuits of the primary fuel level sensor and the secondary fuel level sensor and sends the signal information to the Engine Control Module (ECM) for all further handling. The ECM uses this value in order to determine the fuel level. When the fuel tank is full, the resistances of both fuel level sensors are low, and the ECM senses a low signal voltage on both the signal circuits of the primary fuel level sensor and the secondary fuel level sensor. When the fuel tank is empty, the resistances of the fuel level sensors are high, and the ECM senses a high signal voltage. The ECM uses the signal circuits of the primary fuel level sensor and the secondary fuel level sensor in order to calculate the percentage of remaining fuel in the tank. The ECM sends the fuel level percentage via the serial data circuit to the instrument cluster in order to control the fuel gauge.

The primary fuel level sensor and the secondary fuel level sensor change resistance based on fuel level. The Engine Control Module (ECM) monitors the signal circuits of the primary fuel level sensor and the secondary fuel level sensor in order to determine the fuel level. When the fuel tank is full, the resistances of both fuel level sensors are low, and the ECM senses a low signal voltage on both the signal circuits of the primary fuel level sensor and the secondary fuel level sensor. When the fuel tank is empty, the resistances of the fuel level sensors are high, and the ECM senses a high signal voltage. The ECM uses the signal circuits of the primary fuel level sensor and the secondary fuel level sensor in order to calculate the percentage of remaining fuel in the tank. The ECM sends the fuel level percentage via the serial data circuit to the instrument cluster in order to control the fuel gauge.
The Diagnostic Trouble Code (DTC) will be set if the ECM detects the signal voltage is less than 0.25 V.
What are the Possible Causes of the DTC P2067 2015 GMC Sierra?
- Faulty Fuel Level Sensor
- Fuel Level Sensor harness is open or shorted
- Fuel Level Sensor circuit poor electrical connection
- Faulty Instrument Cluster
- Faulty Engine Control Module (ECM)

Frequently Asked Questions about P2067 2015 GMC Sierra Code
What does the OBDII code P2067 mean for a 2015 GMC Sierra?
P2067 indicates "Fuel Level Sensor 2 Circuit Low Voltage," meaning the vehicle's computer is detecting an issue with the secondary fuel level sensor circuit, often related to low voltage.
What are the common symptoms of P2067 in a 2015 GMC Sierra?
Symptoms may include inaccurate fuel gauge readings, a check engine light, or difficulty in monitoring fuel levels.
What causes the P2067 code to appear?
Common causes include a faulty fuel level sensor, damaged wiring or connectors, corrosion in the circuit, or issues with the fuel tank sending unit.
Can a faulty fuel level sensor trigger P2067?
Yes, a malfunctioning fuel level sensor is a primary cause of this code, as it disrupts accurate voltage readings from the fuel system.
How can I diagnose the P2067 code in my 2015 GMC Sierra?
Start by inspecting the wiring and connectors for damage or corrosion, then test the fuel level sensor for proper voltage and resistance using a multimeter.
Can I drive my 2015 GMC Sierra with the P2067 code?
You can drive the vehicle, but it’s not recommended to ignore the code, as inaccurate fuel readings may lead to running out of gas unexpectedly.
How do I fix the P2067 code?
Repairs may involve replacing the fuel level sensor, repairing damaged wiring, cleaning corroded connectors, or replacing the fuel tank sending unit.
Does the P2067 code affect fuel economy?
While the code itself doesn’t directly impact fuel economy, it can make monitoring fuel levels difficult, potentially leading to inefficient refueling habits.
Will clearing the P2067 code fix the problem?
Clearing the code may temporarily turn off the check engine light, but it won’t resolve the underlying issue causing the fault. Proper diagnosis and repair are necessary.
Is the P2067 code expensive to repair?
The cost depends on the exact issue, but replacing a fuel level sensor or repairing wiring typically costs less than major engine or transmission repairs.
