- Fuel Rail Pressure Sensor harness is open or shorted
- Fuel Rail Pressure Sensor circuit poor electrical connection
First diagnose P119B code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
Cost of diagnosing the P119B code
Labor: 1.0The cost of diagnosing the P119B code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
P119B Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P119B MeaningThe fuel rail pressure (FRP) sensor is placed to the fuel rail and measures fuel pressure in the fuel rail. The sensor transmits voltage signal to the Engine Control Module (ECM). As the pressure increases, the voltage rises. The ECM controls the fuel pressure in the fuel rail by operating high pressure fuel pump. The ECM uses the signal from fuel rail pressure sensor as a feedback signal.
The Engine Control Module (ECM) monitors the Fuel Rail Pressure Sensor. The ECM sets the OBDII code when the Fuel Rail Pressure Sensor is not to factory specifications.
