After a period of time where I noticed the fuel gauge acting erratically (occasionally widely swinging) the check engine light eventually illuminated. Dealer service found code p0464: "inspected cluster for any loose connections or damage, no issue found with cluster or wiring. Removed the sending units and found send units out of spec when moving by hand and ohm senders. Replaced both sending units and cleared codes. ".
