I recently drove my truck and then the code popped up, Now i know its the fuel tank pressure sensor is getting low voltage, but im wondering what would cause it i checked wires and everything in voltage is right so what im asking is how do i take it out of the fuel pump assembly?

thanks ahead of time

  Is this a bottom end issue, if so oil weight is not the reason or cause, i have been running 0-20 weight in my 6.2 since November of 2014 and I'm just about at 100,000 miles. Gm just released a statement yesterday stating they are bringing certain machining back in house for their next gen v-8's. I have been screaming from the rooftops on this issue since easily 2021! These lower end issues all stems from using slave wage labor in Mexico. If you were building a 60-80,000 dollar truck, would you have a guy who makes around 3-5 bucks an hour create the crank shaft for it and finish the surfaces on it? I bet 100 out of 100 people would say hell f'ing no and rightfully so! Gm tried to save penny's and in the end it is costing them millions, not to mention customers who will never look at a single GM product again after this experience!

  You guys won't do anything. You will make him pay a $250 diagnostic fee and hopefully try and find the issue. This has been a known issue with these trucks. If GM says safety is a top priority then GM would make this a recall or some special coverage like the vacuum pump issue.
