ENGINE - 2 Fuel Pressure Regulator - The fuel pressure regulator has been relocated to the left end of the fuel rail. The fuel rail has also been changed to accommodate the regulator.


LH 2.4 Fuel System, 9000S - LH 2.4 is the latest generation of the LH fuel system and is installed in the 9000S. LH 2.2 is the system fitted to 9000 Turbos.
The main difference between this version and earlier types is the expanded memory in the electronic control unit, a new plastic cased air mass meter and a built-in fault diagnosis system. The idle control system is of the adaptive type. This means that the idling speed and AIC setting are adjusted automatically and continuously to compensate for all normal variations. This type of system results in little or no need for idle speed adjustments.

Review the Service Manual Section 0 - "NEWS" for a listing of the fault codes and instructions for retrieving the codes. Later editions of Section 2:3 will also contain this information.
