When the fuel/air mixture ignites, many factors must be met to pass a misfire monitor.
Direct injection pressure is measured with sensors, and you’ll need a scan tool to measure the signals
How do modern gas gauges stay still when the gas in your tank moves around? This video is sponsored by Carter.
The fuel pressure sensor usually has three wires and operates on five volts. What controls the speed of the fuel pump?
Since the fuel pump module needs information for various sensors, it usually communicates on a serial data bus. If modules are not communicating, the fuel pump can’t be adequately controlled. The key to investigating these problems is to communicate with different modules to see what data PIDs are present and which ones are missing.
