So I went to the dealer for a new gas cap because i was getting an error code. It worked for a few days but now the engine light is lit. The gas gage does not move and it will not take gas when i squeeze the pump handle. Posted via the PriusChat mobile app.
I hate to say it but it might be a bladder problem. What DTC code is being generated, and is your gauge empty, full or some where in between (and how much gas do you think is in there)? NO fix for Prius Gas Tank Filling Up Issues | PriusChat is a long thread with issues folks have had. There also is a TSB posted in Fuel Tank and Fuel Gauge Diagnostic Tips: TSB-0163-08 | PriusChat that might be helpful.
