This code specifically points to an issue with the fuel level sensor in the vehicle, which is responsible for measuring the amount of fuel in the tank and sending this information to the engine control module (ECM). The fuel level sensor is a crucial component in ensuring the accurate display of fuel levels on the dashboard and is essential for proper fuel management.
Common Causes of P2068 2017 GMC Sierra
- Faulty fuel level sensor
- Corrosion or damage to sensor wiring
- Issues with the ECM
- Poor electrical connections
- Fuel system contamination
Symptoms of P2068 2017 GMC Sierra
- Inaccurate fuel gauge readings
- Check Engine Light illuminated
- Fluctuating fuel gauge readings
- Engine stalling or hesitating
- Reduced fuel efficiency
How to Fix P2068 2017 GMC Sierra
- Begin by diagnosing the root cause of the issue using a diagnostic scanner to retrieve the fault codes and pinpoint the problem area.
- Inspect the fuel level sensor and its wiring for any signs of damage, corrosion, or loose connections. Replace or repair components as needed.

What are the symptoms of code P2068 on a 2017 GMC Sierra?
Common symptoms include inaccurate fuel gauge readings, a check engine light, and, in rare cases, improper fuel system performance.
What causes the P2068 code on a 2017 GMC Sierra?
Possible causes include a faulty fuel level sensor, damaged or corroded wiring, a poor electrical connection, or issues with the Powertrain Control Module (PCM).
How can I diagnose the P2068 code on my 2017 GMC Sierra?
Start by inspecting the wiring and connectors near the fuel level sensor for damage, corrosion, or looseness. Use a multimeter to test voltage and continuity of the circuit.
Can I drive my 2017 GMC Sierra with the P2068 code active?
While the truck may still be drivable, the inaccurate fuel gauge readings can make it difficult to determine fuel levels, potentially leading to unexpected fuel depletion.
How do I fix the P2068 code on a 2017 GMC Sierra?
Repairs may involve replacing the fuel level sensor, fixing or replacing damaged wiring, cleaning corroded connectors, or reprogramming the PCM if necessary.
How much does it cost to repair the P2068 code on a 2017 GMC Sierra?
Repair costs vary, but replacing a fuel level sensor typically ranges from $200 to $500, including parts and labor. Wiring repairs may cost less.
Will clearing the P2068 code solve the problem on my 2017 GMC Sierra?
Clearing the code without addressing the underlying issue will temporarily reset the check engine light, but the code will likely return.
Is the P2068 code related to the primary fuel level sensor on a 2017 GMC Sierra?
No, P2068 specifically points to issues with the secondary fuel level sensor, commonly found in dual-tank or large-capacity systems.
Do I need any special tools to fix the P2068 code on a 2017 GMC Sierra?
Basic tools like a multimeter and OBD-II scanner are typically required for diagnosing and fixing this code.
