Fuel Cutoff Mode: Notes

To prevent possible engine damage from over-speed, the PCM cuts off fuel from the injectors when the engine speed is above approximately 5800 RPM. Also, see Rapid Deceleration in Deceleration Mode.

The fuel metering system consists of the following parts:

• The fuel supply components:
  • The fuel tank
  • The pump
  • The pipes
• The fuel pump electrical circuit
• The fuel rail
• The fuel injectors
• The fuel pressure regulator
• The throttle body
• The idle air control (IAC) valve
• The throttle position (TP) sensor
