Diagnostic Test

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

ACTIVE DTC
NOTE:
If any other Throttle Body DTCs are present, they must be diagnosed and repaired before continuing this test.

NOTE:
If there is a loss of communication with the ABS Module or implausible data from the ABS Module DTC present, diagnose and repair those faults before proceeding. A Loss of communication w/ABS will default vehicle speed to zero while driving and false fail the idle speed rationality diagnostics, setting this code.

NOTE:
It may be necessary to drive the vehicle to meet the conditions to set this DTC, try to repeat the conditions in which the fault originally set by reviewing the Freeze Frame data.
1. Start the engine.
2. Allow the engine to reach normal operating temperature, road test the vehicle.
3. With a scan tool, select View DTCs.
  Is the DTC Active or Pending at this time?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
PCV SYSTEM
1. Inspect the PCV system for the following problems:
2. Leaks - cracked or damaged hoses or tubes, poor hose or tube connections, PCV valve stuck open, etc.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

VACUUM LEAKS
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 can result in possible serious or fatal injury.
1. Start the engine.
2. Inspect the engine for internal leaks.
3. Inspect any external components that can create a vacuum leak. Inspect the following items, but not limited too:
  - Vacuum supply lines
  - Brake Booster
  - Purge Solenoid
  - Engine seals
  Were any vacuum leaks found?
  
  Yes
  - Repair the vacuum leak as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 4
THROTTLE BODY OPERATION
1. Inspect the throttle body for carbon build up, other restrictions, and a bent throttle plate using a straight edge.
2. If the throttle plate does not close entirely it may be bent and needs to be replaced.
  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 can result in possible serious or fatal injury.
3. While the vehicle is running, perform a wire and connector wiggle test on the ETC Motor wiring and connections, and listen for idle to raise.
  Were any problems found or did the idle fluctuate while performing a wire and connector wiggle test?
  
  Yes
  - Verify that there is good pin to terminal contact at the Throttle Body and the Powertrain Control Module connectors. Replace the Throttle Body Assembly if no problems were found in the connectors. Disconnect the Battery when replacing the Throttle Body Assembly. After installation is complete, use a scan tool and select the Throttle Body Self Learn.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 5
POWERTRAIN CONTROL MODULE (PCM)
NOTE:
Before replacing PCM, verify that there are no vacuum leaks. The most common cause for this DTC is an internal or external vacuum leak.
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Throttle Body and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the Throttle Body and Powertrain Control Module harness connectors.
4. Perform any Technical Service Bulletins that may apply.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
