P229000	Injector control pressure too low	Fuel leak (high or low-pressure system) Fuel filter/line fault Air lock in injection pump Fuel pump fault	There are different approaches to this depending on whether or not the vehicle runs. If the vehicle does not run: remove the lift pump fuse (fuse 1E of the engine compartment junction box). Disconnect the volume control valve connector from the rear of the injection pump. Disconnect the fuel spill lines and direct into a suitable container through a length of clear pipe. Crank the engine to at least 250 rpm for a minimum of 15 seconds. The pump spill flow should be at least 160 ml/min. If the spill flow is greater than this, install a new injection pump. REFER to: Fuel Pump (303-04D Fuel Charging and Controls - TDV8 3.6L Diesel, Removal and Installation). Clear the DTCs and test for normal operation. If the spill flow is less than 160 ml/min, carry out the low-pressure bleeding procedure.

If the fault does not clear, check the low-pressure system to the injection pump. Insert a length of clear pipe into the fuel line and check for a steady flow of fuel with no air bubbles. If the low-pressure system checks out, disconnect the fuel injector electrical connectors and backleak connections. Direct the lines into a suitable container and crank the engine. Compare the flow from the injectors and if there is one or more with low flow, install a new injector to that cylinder.
