My car listed above has a CEL when I scan with an ODM-ll, I get a P0181 code...I Have already tested all the wiring and connections for damage and continuity. Please help... I have been researching for weeks now and I’m at the point where I’m going to lower my fuel tank to see if that’s where a sensor goes because everything on the Internet points to it being integrated into the fuel pump. The problem is, I don’t have any idea where it goes in the fuel pump and the thread on it looks like it’s placed and either the fuel tank or the engine block somewhere.

The fuel temperature sensor can be part of the fuel tank pressure sensor.
