Natural Gas Vehicle (NGV) Module.
WARNING: This page is about a different car, the 2004 Ford RV Cutaway, 2004 Ford Econoline, 2004 Ford E450 Super Duty, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The NGV module assembly:
- Consists of a 90-pin module and a bracket and four retainers.
- Houses the unique electronics required for natural gas fuel systems.
- Is located on the LH inner fender.
The NGV module carries out the following functions:
- Injector drivers: the NGV module accepts eight unmodified injector signals from the powertrain control module (PCM) and allows a peak-and-sustain current to flow through the injector solenoids.
- Fuel gauge driver: the NGV module uses fuel tank temperature and fuel tank pressure inputs to calculate the density of the fuel. A look-up table is used to determine the output signal to the fuel gauge.
