1. INSPECT INJECTION PUMP


  1. Inspect the engine speed sensor.



      A0096QOE01

    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      1 (NE-) - 2 (NE+)
      		20°C (68°F)
      		205 to 255 Ω

      If the result is not as specified, replace the injection pump assembly.



  1. Inspect the spill control valve.



      A00982VE01

    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      1 (SPV-) - 2 (SPV+)
      		20°C (68°F)
      		1 to 2 Ω

      If the result is not as specified, replace the injection pump assembly.



  1. Inspect the fuel temperature sensor.



      A009C2RE01

    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      1 (E2) - 2 (THF)
      		20°C (68°F)
      		2.21 to 2.69 kΩ

      ПРИМЕЧАНИЕ:
      When checking the sensor in water, be careful not to allow water to contact the terminals. After checking, wipe the water off the sensor.

      If the result is not as specified, replace the injection pump assembly.



2. INSPECT TIMING CONTROL VALVE


  1. Inspect the timing control valve.



      A009ARVE01

    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      1 (+B) - 2 (TCV)
      		20°C (68°F)
      		10 to 14 Ω

      If the result is not as specified, replace the timing control valve.

  1. Inspect the timing control valve operation.

    ПРИМЕЧАНИЕ:
    1. Do not apply voltage for more than 30 seconds to avoid burning out the timing control valve solenoid.
    2. When performing this step, wait until the solenoid coils become cool enough that the solenoid can be touched by hand.

  1. Connect the positive (+) lead of the battery to the timing control valve +B terminal.

  1. Connect the negative (-) lead of the battery to the timing control valve TCV terminal.

  1. Check that the solenoid makes a "click" sound.
    If the result is not as specified, replace the timing control valve.



3. INSPECT INJECTION PUMP DELIVERY VALVE SUB-ASSEMBLY


A009B2IE01

ПРИМЕЧАНИЕ:
Do not touch the sliding surface of the delivery valves.

  1. Pull up the valve and release it. Check that it sinks smoothly into the valve seat. If the operation is not as specified, replace the valve and valve seat as a set.

    УКАЗАНИЕ:
    Before using a new valve set, wash off the rust prevention compound with diesel fuel. Then rewash with diesel fuel and perform the above test.
