The fuel pressure sensor (for high pressure side) is installed on the fuel delivery pipe sub-assembly (for high pressure side). The fuel pressure sensor (for high pressure side) changes the fuel pressure for high pressure side into an electrical signal and sends the signal to the ECM. Then the ECM controls the pump discharge using this feedback to maintain the fuel's target pressure between 4.0 and 20 MPa (41 and 204 kgf/cm² ).

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory	Note
P0190-11	Fuel Rail Pressure Sensor "A" Circuit Short to Ground	The fuel pressure sensor (for high pressure side) output voltage is less than 0.2933 V for 3 seconds or more (1 trip detection logic).	Open or short in fuel pressure sensor (for high pressure side) circuit Fuel delivery pipe sub-assembly (fuel pressure sensor (for high pressure side)) ECM	Comes on	DTC stored	SAE Code: P0192

HINT:

When this DTC is output, check the fuel pressure (for high pressure side) in the Data List. Enter the following menus: Powertrain / Engine / Data List / Fuel Pressure (High).

DTC No.	Fuel Pressure (High)	Malfunction
P0190-11	Approximately 0 kPag	Short to ground in PR circuit Short in PR to EPR circuit Open in VCPR circuit

If the Data List values is normal it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
