CIRCUIT DESCRIPTION The Powertrain Control Module (PCM) enables the appropriate fuel injector on the intake stroke for each cylinder. A voltage is supplied directly to the fuel injectors. The PCM controls each fuel injector by grounding the control circuit via a solid state device called a driver. A fuel injector coil winding resistance that is too high or too low will affect the engine driveability. A fuel injector control circuit DTC may not set, but a misfire may be apparent. The fuel injector coil windings are affected by the temperature. The resistance of the fuel injector coil windings will increase as the temperature of the fuel injector increases. DIAGNOSTIC AIDS Monitoring the misfire current counters, or misfire graph, may help to isolate the fuel injector that is causing the condition. Operating the vehicle over a wide temperature range may help to isolate the fuel injector that is causing the condition. Perform the fuel injector coil test within the conditions of the customers concern. A fuel injector condition may only be apparent at a certain temperature, or under certain conditions. If the fuel injector coil test does not isolate the condition perform the fuel injector balance test. Refer to Fuel Injector Balance Test with Special Tool or Fuel Injector Balance Test with Tech 2.

Start By: A. Remove the valve mechanism cover. Refer to Disassembly and Assembly, “Valve Mechanism Cover – Remove and Install”. NOTICE Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. NOTICE Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, “Caterpillar Tools and Shop Products Guide” for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. Removal Of The Injector 1. Remove oil drain plugs (1) at each end of the cylinder head. 2. Allow the engine oil to drain from the ports in the cylinder head before the injector is removed. 3. Disconnect harness connector (2) . Note: Some of these engines were built without the deflector. During the installation of the unit injectors, the deflectors (Y) should be installed. 4. Remove bolt (3) . 5. Remove bolt (4) . 6. Place Tooling (A) under clamp (5) on the flywheel side of the injector. 7. Tooling (A) should be placed at this location in order to gently remove the injector. Use Tooling (A) to remove the injector. 8. Do not pry at location (Z) . 9. Remove the O-Ring seals (6) from the injector. 10. Repeat Step 3 through Step 9 for the remainder of the injectors. Cleanliness is very important in the area around the sleeve and the sleeve bore when you are reinstalling the injector. This injector has a metal seal (7) between the bottom of the injector’s case and a seat in the cylinder head. Clean the carbon from the seat area that is inside of the cylinder head. Also clean the carbon from the end of the injector if the injector should be reinstalled. The fine grade of the Scotch Brite material is preferred. Scotch Brite is available from the Tools And Shop Products Guide as the abrasive material and as the surface reconditioning pad. If the sleeve of the injector has been removed from the engine, use a reamer to remove carbon deposits from the angled surface. Note: Do not use the reamer in order to remove metal from the sleeve. Use the reamer in order to remove carbon only.

Removal 1. Disconnect the battery ground cables. 2. WARNING: RED-STRIPED WIRE HARNESS CARRIES 115V DC. SEVERE ELECTRICAL SHOCK MAY BE RECEIVED. DO NOT PIERCE. CAUTION: Do not attempt to service the fuel injector. The fuel injector is serviced as an assembly. If the fuel injector is disassembled for any reason, the calibration of the fuel injector will be inaccurate. There are two different fuel injectors used in the 7.3L DI turbo diesel engine: a 49-state injector and the California injector (rate shaped injector). These two injectors must not be interchanged because the Powertrain Control Modules are calibrated to the specific injector. Before replacing any injectors, refer to the Vehicle Emission Control Information (VECI) decal for proper injector selection. Failure to do so can cause poor engine performance, high emissions levels or damage to engine. Remove the engine cover. 3. Remove the two (2) nuts retaining the air cleaner-outlet tube support bracket to the left valve cover. Remove the engine harness bracket from the air cleaner- outlet tube support bracket and position aside. 4. Remove and discard the crankcase ventilation hose clamp and disconnect the hose. Loosen the clamps at the turbocharger and air cleaner and disconnect the intake duct and outlet tube. 5. Remove the bolt and nut retaining the air cleaner assembly, disconnect the air intake sensor and remove the air cleaner assembly. 6. CAUTION: Do not pierce engine electrical wires or damage to the harness can occur. Remove the engine harness tie strap from the left engine-lifting bracket. 7. Remove the two (2) crankcase breather filter retaining screws and remove the crankcase breather filter from the left valve cover. 8. Remove the left valve cover. 9. Disconnect the electrical connectors from the left valve cover gasket. Remove the valve cover gasket. 10. Disconnect the electrical connectors from the left fuel injectors and the glow plugs. 11. Drain the oil from the left cylinder head by removing the internal oil rail drain plugs. 12. Remove the left oil deflectors. 13. WARNING: DO NOT ROTATE THE CRANKSHAFT WITH THE FUEL INJECTOR REMOVED. OIL AND FUEL WILL ENTER THE COMBUSTION CHAMBER WHICH COULD CAUSE ENGINE DAMAGE OR PERSONAL INJURY. NOTE: The shoulder bolt on the inboard side of the fuel injector does not require removal. Remove the left outboard fuel injector-retaining bolts.

Circuit Description The control module enables the appropriate fuel injector on the intake stroke for each cylinder. An ignition 1 voltage is supplied directly to the fuel injectors. The control module controls each fuel injector by grounding the control circuit via a solid state device called a driver. Diagnostic Aids • Monitoring the fuel injector circuit status with a scan tool, while moving the fuel injector harness, may help to isolate an intermittent condition. • Performing the Fuel Injector Coil Test may help isolate an intermittent condition. Refer to Fuel Injector Solenoid Coil Test . • For an intermittent condition, refer to Intermittent Conditions . Test Description The numbers below refer to the step numbers on the diagnostic table. 4. This step tests for a short to ground on the ignition 1 voltage supply circuit of the fuel injector. 5. This step tests for an open ignition 1 voltage supply circuit between the injector fuse and a fuel injector electrical connector.
