Step 11 - Step 12
The numbers below refer to the step numbers in the diagnostic table.
1. The Diagnostic System Check - Vehicle prompts the technician to complete some basic checks and store the Freeze Frame data on the scan tool, if
applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored in the scan tool for later
reference.
3. This step determines whether the fuel pump can provide fuel within the correct regulated pressure range.
4. This step tests that the fuel system can maintain fuel pressure with the pump OFF. A fuel pressure drop of more than 55 kPa (8 psi) within the
specified time indicates a leak in the fuel system.
6. This step determines whether the loss in fuel pressure is on the fuel tank side of the system or the fuel rail side.
7. This step tests the operation of the fuel pressure regulator. If the fuel pressure exceeds the specified value, the fuel pressure regulator is faulty.
8. This step tests for a restriction in the fuel system.
