Troubleshooting for CC1: Short circuit to +12 V
Check the fuel flow actuator connector.
Check the ECM connections.
Check the low pressure circuit and that the correct fuel is being used using fault finding
• Tests Test 2 referring to "Test 2: Low pressure circuit check: For Diesel Engine Model".
Repair if necessary.
Measure the resistance of the fuel flow actuator between "C83-1" and "C83-2" terminals.
If the resistance is not 2.9 – 3.1 Ω at 20 °C, 68 °F, replace the fuel flow actuator.
Check the continuity and insulation from the +12 V feed of the following connection:
• Between "C83-2" wire of the fuel flow actuator connector and "C86-7" terminal of ECM connector
Check the fuel pressure sensor using the interpretation of "DTC P0190: Fuel Pressure Sensor Circuit: For Diesel
Engine Model".
If the fault is still present replace the fuel flow actuator.
Troubleshooting for CC0: Short circuit to vehicle body ground and CO: Open circuit
Check the fuel flow actuator connector.
Check the ECM connections.
Check the low pressure circuit and that the correct fuel is being used using fault finding
• Tests Test 2 referring to "Test 2: Low pressure circuit check: For Diesel Engine Model".
Repair if necessary.
Measure the resistance of the fuel flow actuator between "C83-1" and "C83-2" terminals.
If the resistance is not 2.9 – 3.1 Ω at 20 °C, 68 °F, replace the fuel flow actuator.
Check the continuity, and insulation from vehicle body ground of the following connection:
• Between "C83-2" wire of fuel flow actuator connector and "C86-7" terminal of ECM connector
With ignition switch ON, check for +12 V on "C83-1" of the fuel flow actuator.If there is not +12 V on "C83-1",
check the continuity and absence of interference resistance of the following connection:
• Between "C83-1" wire of fuel flow actuator connector and "E33-6" wire of main relay mounting connector
Repair if necessary.
Check the fuel pressure sensor using the interpretation of "DTC P0190: Fuel Pressure Sensor Circuit: For Diesel
Engine Model".
If the fault is still present replace the fuel flow actuator.
