I have a 2011 Infiniti QX56 and a couple weeks ago my engine light came on and my husband checked what was wrong with it and a code came up P0183 which is the Fuel Temp Sensor A Circuit. My truck has been lagging and stalling while driving with no force. We were told the it is the fuel sensor or something that is located in the gas tank. My truck hardly drives now. Does someone have similiar issues or can direct me as to what to do what can it be etc. Thanks
