Electrical problem
2001 Chevy Suburban V8 Four Wheel Drive Automatic 150K+ miles
I put a fuel pump in this vehicle several months ago and it fixed the problem with it losing power and not running at all until you let it sit for an hour or so. It's been fine for several months. Now I have gotten the computer to spit out two fault codes related to the evaporative emmisions pressure sensor in the fuel tank. One code (the one It has registered most frequently) says this sensor has a low input. It did however trip the check engine light after I had reset it once with a similar code that read high input. I can see a gas cap, or leaking line in this system causing a consistent low input fault code, but if it is occasionally tripping a code and reading a high input on this same sensor, is it the sensor?
