Turning the key only to hear the engine crank without firing is stressful, but this specific fuel pressure sensor code gives us a solid lead. This video clarifies that this code usually points to the electrical circuit monitoring the pressure, not necessarily the fuel pump itself. We are dealing with a sensor that tells the computer how much fuel to deliver, and if the wiring is bad, the computer is blind. I will explain how to test the three main wires: the five-volt reference, the signal, and the ground. We will talk about checking for rodent damage or broken wires in the harness and the importance of verifying the actual pressure with a mechanical gauge to confirm if the sensor is lying to the computer.
