2003 Nissan 350Z P0183 and P0447 Fault Codes - Gas Gauge Reads Empty After Replacing Fuel Temperature Sensor and Sending Unit

Model: 2003 nissan 350z Fault Code: P0183 Posted: 2020-07-05 09:20

I am experiencing fault codes P0183 and P0447 on my 2003 Nissan 350Z. The gas gauge consistently reads empty, even when fuel is present. I have already replaced both the fuel temperature sensor and the fuel sending unit (coded NW7). Despite these repairs, the issue persists. I'm seeking advice on possible causes or next steps to resolve this problem, especially in relation to the P0183 and P0447 diagnostic codes.
