WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

The fuel rail sensor reads the oncoming temperature of the CNG fuel entering the fuel rail. The information is sent to the Powertrain Control Module (PCM) were it will calculate the temperature and pressure readings for the required fuel injection timing.
