Question about Cars & Trucks
SOURCE: 2002 Chevy Impala Sensor # 3
You didn't give the engine size, so I'll give what my manual shows.
The 3.4L engine----- 2nd one in from the left, in back of the engine.
The 3.8L engine------2nd one in from the left, in front of the engine.

There is no sensor for a loose gas cap. What is happening is that the evaporative emission system is sensing a "Large Leak". Usually code p0455. The computer sees this as the most probable cause is a loose gas cap depending on several factors it looks at. You would need to clear the code(s) and see if that was the problem. If the light comes back on, then you have a problem in the system that will not let it seal. Possible solenoid problem, leaking hose / line, etc.
