P119C Code - Fuel Rail Pressure Sensor Malfunction
Quick Answer
The fuel rail pressure (FRP) sensor is placed to the fuel rail and measures fuel pressure in the fuel rail. Common causes include Faulty Fuel Rail Pressure Sensor, Fuel Rail Pressure Sensor harness is open or shorted, Fuel Rail Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P119C Description
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.
What are the Possible Causes of the DTC P119C?
- Faulty Fuel Rail Pressure Sensor
- Fuel Rail Pressure Sensor harness is open or shorted
- Fuel Rail Pressure Sensor circuit poor electrical connection
How to Fix the DTC P119C?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P119C code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
