Fuel Pressure Sensor: Inspection: Procedure

HINT: 

The fuel pressure sensor cannot be removed as a single unit. When replacing the fuel pressure sensor, replace it together with the fuel distributor as a single unit.

1. Connect the techstream to the DLC-2.
2. Switch the ignition ON (engine off).
3. Start the engine and warm it up completely.
4. Verify that the fuel pressure sensor output voltage (PID: Fuel pressure sensor) is within the specification.
