OBD Code P0192refers to
The Fuel Rail Pressure (FRP) sensor is a diaphragm strain gauge device in which resistance changes with pressure. The electrical resistance of a strain gauge increases as pressure increases, and the resistance decreases as the pressure decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signal to the Powertrain Control Module (PCM) corresponding to pressure. Strain gauge type sensors are consider passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. The FRP sensor measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each combustion cylinder.

Naravno da ta greška ukazuje na pritisak goriva u vodu, ali više stvari mogu da dovedu do toga. Ja sam prvo sumnjao na instalaciju, ali su mi električari nakon dijagnostike rekli da je posao za mehaničara. Kod mehaničara naravno prvo krenu od dizni i pvp za svaki slučaj, zbog toga sam napomenuo da sam imao sreće.
