Code P2067 2014 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 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 2014 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 2014 Chevrolet Silverado Code
What does the OBDII code P2067 mean for a 2014 Chevrolet Silverado?
The P2067 code indicates a low voltage issue in the Fuel Level Sensor 2 circuit, which monitors the fuel level in the secondary fuel tank or system.
What are the common symptoms of a P2067 code?
Symptoms may include an inaccurate or fluctuating fuel gauge, an illuminated check engine light, or erratic fuel level readings.
What causes the P2067 code in a 2014 Chevrolet Silverado?
Possible causes include a faulty fuel level sensor, damaged wiring or connectors in the sensor circuit, a malfunctioning fuel pump module, or a short to ground in the circuit.
Can I still drive my Silverado with a P2067 code?
Yes, but it’s not recommended for extended periods since the inaccurate fuel readings may lead to running out of fuel unexpectedly.
How do I diagnose the P2067 code?
Start by inspecting the wiring and connectors for damage, test the fuel level sensor with a multimeter, and verify the voltage and ground signals in the circuit.
Can a bad fuel pump cause a P2067 code?
Yes, if the fuel pump module contains the fuel level sensor and it fails, it could trigger a P2067 code.
How is the P2067 code fixed?
Repairs may involve replacing the faulty fuel level sensor, repairing or replacing damaged wiring or connectors, or replacing the fuel pump module if it includes the sensor.
How much does it cost to fix a P2067 code?
The repair cost depends on the specific issue but can range from $150 to $600, with fuel level sensor replacement being a common expense.
Can a software update fix the P2067 code?
In rare cases, a software update to the vehicle’s ECM may resolve the issue if it’s related to incorrect calibration, but this is uncommon for this code.
Will clearing the P2067 code solve the problem?
Clearing the code may turn off the check engine light temporarily, but the issue will likely return unless the underlying problem is addressed.
