Fuel injectors spray the fuel into the manifold through a nozzle. Then the fuel combines with the air. Thus, engine combustion takes place by burning them.

Due to combustion, carbon deposits are produced. These deposits can clog the fuel injectors opening. For this reason, a sufficient amount of fuel can’t enter the combustion chamber. So, the 07e8 code pops up on the display.

2. Clogged fuel filter: 

The fuel filter is used to remove the sediments from the fuel. It helps to purify the fuel. But as time goes by, it collects debris from the fuel before the fuel enters the fuel injector.

As a result, it gets clogged and fuel can’t pass properly from the clogged obstacle. Thus, the sensors detect the malfunction and show the 07e8 code.

3. Broken fuel pump: 

Fuel pumps are like the heart of an engine. It takes the proper amount of fuel from the fuel tank and passes it through the air filters and fuel injector.

If the pump malfunction, there occurs a fuel intake issue. Gradually the sensors detect the fuel intake issue and the result is the 07e8 code.

4. Dirty air filter: 

For combustion, the air is mixed with the fuel. This air is collected from the atmosphere. Then it passes through the air filter before entering the manifold.

Air filters remove the dirt from the air for complete combustion. Thus, the air filter becomes dirty and can’t draw sufficient air for the engine. It alarms the Chevy suburban’s ODB sensor. And it shows the 07e8 code.
