Code P2067 2016 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 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 2016 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 2016 GMC Sierra Code
1. What does the OBDII code P2067 mean for a 2016 GMC Sierra?
P2067 indicates "Fuel Level Sensor 2 Circuit Low Voltage," meaning the vehicle's computer has detected a low voltage signal from the secondary fuel level sensor.
2. What are the common symptoms of code P2067 in a 2016 GMC Sierra?
Common symptoms include inaccurate fuel gauge readings, a check engine light, possible stalling, and difficulty determining fuel levels.
3. What causes the P2067 code in a 2016 GMC Sierra?
Possible causes include a faulty fuel level sensor, damaged wiring or connectors, corrosion in the circuit, or issues with the powertrain control module (PCM).
4. Can I continue driving my 2016 GMC Sierra with a P2067 code?
While the vehicle may still drive, inaccurate fuel readings can lead to running out of fuel unexpectedly, so it’s recommended to address the issue promptly.
5. How is the P2067 code diagnosed?
A mechanic will use an OBDII scanner, inspect the fuel level sensor and wiring, test for proper voltage, and check for corrosion or damaged connectors.
6. How do I fix code P2067 in my 2016 GMC Sierra?
Repairs may include replacing the faulty fuel level sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming the PCM if necessary.
7. How much does it cost to repair a P2067 code on a 2016 GMC Sierra?
Repair costs vary, but replacing a fuel level sensor typically costs between $200 and $500, including parts and labor.
8. Can a bad fuel pump cause code P2067 in a 2016 GMC Sierra?
While uncommon, issues with the fuel pump assembly, which houses the fuel level sensor, could potentially contribute to the P2067 code.
9. Will clearing the P2067 code fix the problem on my 2016 GMC Sierra?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be resolved to prevent the code from returning.
10. Is P2067 a common issue in the 2016 GMC Sierra?
It’s not extremely common, but it can occur, especially in vehicles with high mileage or those exposed to harsh environmental conditions that can damage wiring or sensors.
