Fuel level sensor high voltage detected. HTH. -Jim

Catalyst temp range low.... you have a sensor in front and behind the catalyst converter.. if the temps are not in a certain range this can trigger this code.. it could just be the o2 sensor located in front of the catalyst converter.. that would be bank 1


That's absolutely false! Also, bank 1 is anything that is on the #1 cylinder side of the engine. If we were talking about an inline engine then everything comes up "bank 1". The two sensors that you're referring to are the upstream oxygen sensor (ahead of the catalytic converter) and the downstream oxygen sensor (behind the catalytic converter). They have nothing to do with this trouble code and are not referred to as bank 1 or bank 2! -Jim


Jim. The code has nothing to do with fuel level.. I have had the car since new and mine has 270,000 us miles. I'm sure I know I have had every code imaginable .. Still the first O2 sensor you run into


Are you in the United States? U.S. vehicles built for export to other countries have different computer systems and different trouble codes. I apologize for sounding harsh but I researched this then double checked myself. Then I thought some more about this and it occurred to me that the catalytic converter temp sensor that you're referring to is on some export vehicles. Buicks in the U.S. don't have that. -Jim
