P0190 - Fuel Rail Pressure Sensor Circuit Malfunction

It's on the fuel rail that feeds the injectors. This is the best drawing I could find.

Be aware diagnostic fault codes never say to replace a part or that one is bad. When a part is referenced in a fault code, it is actually the cause of that code about half of the time. First we have to rule out wiring and connector terminal problems before spending your money on a part.

Thank you for your answer to this. Yes, the part, (depending where you source it from) can be rather "pricey". Stuart.
