If there is both a reference signal and ground signal, test the sensor resistance.

If this test is successful, test the ground wire. Test the reference voltage of the fuel rail pressure sensor, using a digital volt ohmmeter, while the car is running. If these components are operational, inspect the fuel rail pressure sensor. If there is no battery voltage at the fuel pump connector, they will check the fuse circuit, fuel pump relay circuit, and power control module circuit for any faults. If the car does not start, they will check the battery voltage at the fuel pump connector. If the car starts, this means that the fuel pump needs to be replaced. If the car won’t start and they cannot hear the fuel pump, they will try starting the car while another person taps on the bottom of the fuel tank. If the car won’t start, but they can still hear the fuel pump, the fuel injector circuitry could be faulty or a fuel filter could be clogged. To make sure the fuel pump is operating properly, the mechanic will listen to it. Low fuel pressure is an indication that the car has little to no fuel. Use a fuel pressure gauge to test the fuel pressure. If the car will not start, there is a possibility that there is no fuel in the fuel tank. Intermittent problems may need to get worse before a proper diagnosis can be made.

If the trouble code P0193 does not return immediately, this indicates the possibility of an intermittent issue. They will complete a test drive, after clearing the codes, to see if the P0193 trouble code returns.

They will use an OBD-II scanner to retrieve freeze frame data and trouble codes stored by the power control module. Repairing the wiring and connections if necessary. The mechanic will start by inspecting the wiring and connectors for melted wires, broken wires, and corrosion. How does a mechanic diagnose the P0193 code?

  • The car will hesitate during acceleration.
  • The car will take longer than normal to start.
  • Wiring that is exposed, broken, shorted, or corroded.
  • When this happens the P0193 trouble code will be stored by the power control module and the Check Engine Light will come on. The power control module (PCM) has detected that the fuel pressure is not within a range that has been predetermined by the vehicle manufacturer.
