Code P2067 2017 Chevrolet Silverado 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 2017 Chevrolet Silverado?
- 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 2017 Chevrolet Silverado Code
What does the OBDII code P2067 mean on a 2017 Chevrolet Silverado?
P2067 indicates a "Fuel Level Sensor 2 Circuit Low Voltage," meaning the fuel level sensor for the secondary fuel tank is reporting a voltage lower than expected.
What are the common symptoms of a P2067 code?
Symptoms include an inaccurate fuel gauge reading, the fuel gauge stuck at empty or full, a check engine light, and potential issues with fuel system performance.
What causes the P2067 code to appear?
Common causes include a faulty fuel level sensor, damaged wiring or connectors in the sensor circuit, corrosion, or a malfunctioning fuel pump assembly.
Can a bad fuel level sensor cause drivability issues?
While it typically doesn’t affect engine performance, a faulty fuel level sensor can lead to inaccurate fuel readings, increasing the risk of running out of fuel unexpectedly.
How can I diagnose the P2067 code?
Start by checking the wiring and connectors for damage or corrosion, test the fuel level sensor’s resistance, and use a scan tool to monitor fuel level sensor voltages.
Can I still drive my truck with a P2067 code?
You can drive with a P2067 code, but it’s risky as the fuel gauge may not provide an accurate reading, increasing the chance of running out of fuel.
How is the P2067 code fixed?
Repairs may include replacing the faulty fuel level sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or replacing the fuel pump module if necessary.
Is the P2067 code covered under warranty for a 2017 Chevrolet Silverado?
It depends on your warranty coverage. Check with your dealership to see if fuel system components are covered under your vehicle’s warranty.
How much does it cost to repair a P2067 code?
Repair costs can vary but typically range from $200 to $600, depending on whether the fuel level sensor or fuel pump module needs replacement.
Can a failing fuel pump cause a P2067 code?
While uncommon, a failing fuel pump assembly that houses the fuel level sensor could contribute to the issue and trigger the code.
