Where is the fuel control actuator located?

Where is the fuel control actuator located?

The Fuel Control Actuator is located at the rear of the high-pressure, fuel injection pump (Fig. 13).

How do you test a fuel control actuator?

Ignition on, engine not running. Disconnect the Electronic Fuel Control Actuator connector. Connect an incandescent test light across the Fuel Control Actuator driver pin and the Fuel Control Actuator return wire at the fuel control actuator connector. Observe the test light.

What is fuel pump actuator?

The Fuel Control Actuator (FCA) or Fuel Pressure Regulator is an electronically controlled solenoid valve. The ECM controls the amount of fuel that enters the high-pressure pumping chambers by opening and closing the FCA based on a demanded fuel pressure.

What to do if fuel control actuator is not working?

Ignition on, engine not running. Disconnect the Fuel Control Actuator (FCA) harness connector. Connect an incandescent test light across the Fuel Control Actuator driver circuit and the Fuel Control Actuator return circuit at the fuel control actuator harness connector.

What are the symptoms of a failing 6.7L Cummins fuel control actuator?

What are the symptoms of a failing 6.7L Cummins Fuel Control Actuator? Rattling Noise from the engine, which sounds like Fuel Knock. It decreased the engine power output level. Engine operation is rough. Engine RPM surging. A surging or loping idle. A faulty fuel pressure regulator causes these symptoms.

How to measure resistance of fuel control actuator?

Measure the resistance of the (K65) return circuit between the FCA harness connector and the ECM harness connector. Is the resistance less than 10 Ohms? Repair or replace the engine wiring harness. Perform POWERTRAIN VERIFICATION TEST (DIESEL). (Refer to 9 – ENGINE – STANDARD PROCEDURE) 4.

How to test fuel control actuator Cummins CP3?

Connect an incandescent test light across the Fuel Control Actuator driver circuit and the Fuel Control Actuator return circuit at the fuel control actuator harness connector. Observe the test light.

How does the fuel control actuator work?

The Fuel Control Actuator is an electronically controlled solenoid valve that is constructed with corrosion-resistant external housing for increased component durability. The ECM controls the amount of fuel that enters the high-pressure pumping chambers by opening and closing the FCA based on demand.

How to check fuel control actuator CP3 diagnosis?

Measure the voltage between the (K65) FCA return circuit in the FCA harness connector and battery negative. Is the voltage greater than 1 volts? Repair the (K65) FCA return circuit shorted to external voltage. Perform POWERTRAIN VERIFICATION TEST (DIESEL). (Refer to 9 – ENGINE – STANDARD PROCEDURE) 6.

How to test a Cummins fuel control actuator?

1. FUEL PUMP Ignition on, engine not running. Disconnect the Fuel Control Actuator (FCA) harness connector. Connect an incandescent test light across the Fuel Control Actuator driver circuit and the Fuel Control Actuator return circuit at the fuel control actuator harness connector. Observe the test light.

What is voltage of fuel control actuator k604?

(K604) FUEL CONTROL ACTUATOR DRIVER CIRCUIT SHORTED TO EXTERNAL VOLTAGE Measure the voltage between the (K604) FCA driver circuit in the FCA harness connector and battery negative. Is the voltage greater than 1 volts? Repair the (K604) FCA driver circuit shorted to external voltage.
