What is the reason for the high voltage fault of Cruze fuel system?

Cruze reported that the high voltage failure of the fuel system may be caused by these two reasons:

The valve cover is broken.

The solution can be solved by cleaning the carbon deposit in the throttle nozzle.

When cleaning the throttle, check whether there is oil behind the throttle, which indicates that the valve cover is broken. Need replacement. The high voltage of Cruze fuel system is usually the problem here.

Maybe it's related to the mixture, maybe it's too rich. It is necessary to check the data flow with a computer to check the intake air volume and the fuel injection pulse width. And then start here.

Solution to high voltage fault of transmitter fuel reporting system;

1, gasoline pressure 345-414;

2. Carbon canister solenoid valve;

3. Air flowmeter, comparing the actual flow and calculating the flow value; When the oil cover leaks, the fuel adjustment will be thin. The diagnosis depends on the data flow. Strong fuel regulation means less air intake, more oil and weak ignition.
