The OBD code P008B indicates a high fuel pressure condition in the fuel system.
This code affects the Fuel Rail Pressure (FRP) Sensor circuit.
Symptoms include the Engine Light being ON.
Causes may include high fuel pressure, a faulty FRP sensor, open or shorted FRP sensor harness, or poor electrical connections.
This issue should be addressed promptly to prevent potential engine damage.
A possible fix involves inspecting and repairing any damaged components or wiring connections related to the FRP sensor circuit.

Details of the p008b OBD Code
Code P008B indicates a lowpressure fuel system performance issue in the vehicle.
OBD code P008B means that the fuel pressure regulator 1 performance has exceeded the learning limit.
This code is triggered by the Engine Control Module (ECM) when it detects that the actual fuel pressure does not match the desired fuel pressure.
The ECM monitors the fuel pressure sensor signal to determine if the fuel pressure regulator is functioning properly.
If the actual fuel pressure deviates significantly from the desired pressure, the ECM will set code P008B.
Mechanic’s Tech Notes
Code P008B indicates a lowpressure fuel system performance issue in the vehicle.
OBDII code P008B indicates a low voltage condition in the engine coolant temperature sensor circuit.
To diagnose this, use a voltmeter to check the voltage at the engine coolant temperature sensor connector.
Ensure the sensor is receiving proper voltage and ground.
Use a scan tool to monitor the sensor’s data and compare it to the actual engine temperature.
Visually inspect the wiring harness and connectors for any damage, corrosion, or loose connections.
Check the connector pins for any signs of being broken, bent, or pushed out.
Repair or replace any faulty components as needed to resolve the issue.
