Fuel and Fuel Control

The fuel control torque values are listed in Table 2-4. Listed in Table 2-5 are the fuel system
torque values. See Figure 2-23 for a harness drawing of the wiring from the PLD (pump and
nozzle) control unit. For a detailed (partial) harness drawing showing the interface between the
PLD and the vehicle control unit (VCU) through the electronic engine frontwall connector,
see Figure 2-24. For a detailed (partial) harness drawing showing the PLD wiring to the
proportioning valves and the oil system sensors, see Figure 2-25. For a detailed (partial) harness
drawing showing the PLD wiring to the other system sensors, including charge air, coolant, fuel,
crank angle position, and TDC (top dead center), see Figure 2-26.
