Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

DTC IS ACTIVE
NOTE:
Diagnose and repair any system voltage or sensor reference voltage DTCs before continuing with this test.
1. Start the engine and allow it to reach normal operating temperature.
  WARNING:
  When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.
2. With the scan tool, select View DTCs.
  Is the status Active for this DTC?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .

1. Turn the ignition off.
2. Disconnect the Fuel Injector 4 harness connector.
3. Turn the ignition on.
4. Using a 12-volt test light connected to ground, check the (F342) Fused ASD Relay Output circuit in the Fuel Injector 4 harness connector.
  NOTE:
  The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
  
  Is the test light illuminated and bright?
  
  Yes
  - Go To 3
  No
  - Repair the (F342) Fused ASD Output circuit for an open circuit or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
(K14) INJECTOR 4 CONTROL CIRCUIT OPEN OR HIGH RESISTANCE

1. Turn the ignition off.
2. Disconnect the Powertrain Control Module (PCM) C2 harness connector.
3. Measure the resistance of the (K14) Injector 4 Control circuit between the Fuel Injector 4 harness connector and the PCM harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 4
  No
  - Repair the (K14) Injector 4 Control circuit for an open circuit or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

FUEL INJECTOR 4

Turn the ignition off.

Measure the resistance between the terminals of Fuel Injector 4.

NOTE:

The resistance of the circuit will vary according to the temperature of the injector coil. Use the table below to determine the resistance range of the injector.

Fuel Injector Coil Resistance Based on Engine Temperature
Temperature	Resistance
-20° C (-4° F)	10 Ohms (+/-.6 Ohm)
20° C (68° F)	12 Ohms (+/-.6 Ohm)
60° C (140° F)	14 Ohms (+/-.6 Ohm)
100° C (212° F)	16 Ohms (+/-.6 Ohm)

Is the resistance of the injector within the specified range?

Yes

Go To 5

Replace Fuel Injector 4 in accordance with the Service Information. Refer to INJECTOR(S), FUEL, REMOVAL .
Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Fuel Injector 4 and the Powertrain Control Module (PCM).
  - Look for any chafed, pierced, pinched, or partially broken wires.
  - Look for broken, bent, pushed out or corroded terminals.
  - Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
  - Look for the data to change or for the DTC to reset during the wiggle test.
  - Perform any Technical Service Bulletins that may apply.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
