Diagram of the engine bay showing the injector resistor location and a connector pinout view with terminals labeled A, B, C, E, F
Schematic diagram of the injector resistor showing internal resistance paths between terminals A, B, C, E, and F

19M0515

  1. Injector resistor
  2. Disconnect the injector resistor connector.
  3. Check the resistance between each of the injector resistor terminals (F, E, C and B) and the power terminal (A).
  4. Resistance should be 5 – 7 Ohms.
  5. Replace the injector resistor with a new one if any of the resistances are outside of the specification.

FUEL PRESSURE REGULATOR

Testing

WARNING: Do not smoke during the test. Keep open flames away from your work area.

Diagram showing a fuel pressure gauge connected to the fuel rail service port, with callouts for the fuel pressure regulator and clamp

19M0518

  1. A Fuel pressure regulator
  2. B Clamp
  3. Attach a fuel pressure gauge to the service port of the fuel rail. Start the engine and allow it to idle. The fuel pressure should be 280 – 330 kPa (with the fuel regulator vacuum hose disconnected and clamped)
  4. Reconnect the vacuum hose to the fuel pressure regulator.
  5. Check that the fuel pressure rises when the vacuum hose from the fuel regulator is disconnected again.
  6. If the fuel pressure does not rise, replace the fuel pressure regulator.
