2011 Jeep Grand Cherokee Limited P2006 Fuel Level Sensor Error: Is It the Auxiliary Tank?
Hi everyone, I own a 2011 Jeep Grand Cherokee Limited with a 5.7L Hemi engine, and I'm consistently receiving a P2006 fuel level sensor error from my OBD-II scanner. The code specifically points to Sensor 2. Given that this vehicle comes standard with two fuel tanks—one main tank and one auxiliary tank on the passenger side—I’m wondering if this error is actually related to the auxiliary gas tank. While I suspect this might be the case, I’d like confirmation before proceeding with any repairs. I'm concerned about potentially dropping the wrong tank during maintenance, which could lead to unnecessary costs and time. Does anyone have experience with this issue or know whether P2006 in a 2011 Grand Cherokee Limited typically points to the auxiliary fuel tank? Thanks for your help! — Jay
Strongly recommend using a different OBD-II scanner to verify the code — many auto parts stores offer free diagnostics as part of their customer service, which can help confirm whether the P2006 error is accurate and specific to Sensor 2.
