2001 Rodeo gas gauge and check engine light Sign In

I have a 2001 Isuzu Rodeo Sport, 2wd, automatic, 2.2L 4cyl with approx. 90,000 miles. Every once in a while my gas gauge will drop to empty and at the same time the check engine light will come on. I haven't tried anything yet because it runs great while all this is happening. It is frustrating to not be able to use the gas gauge with any faith. Eventually the gas gauge will move from empty but the check engine light still stays on. The check engine eventually goes out after about 2 or 3 stops and I restart my car. Does anyone know what the problem is?

There’s a good possibility that the sending unit in the tank is at fault. The check engine light is coming on because the PCM (computer) needs to know how much fuel is in the tank; as to perform certain emission tests.
