Diagnostic Test

WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.
  1. DTC IS ACTIVE 
    1. Turn the ignition on.
    2. With the scan tool, Clear DTCs in the Powertrain Control Module (PCM).
    3. 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.

    4. With the scan tool, select View DTCs.

      Is the status Active for this DTC?

      Yes 

      • Go To  2

    1. Turn the ignition off.
    2. Disconnect the Manifold Flow Valve harness connector.
    3. Using a 12-volt test light connected to 12 volts, check the (Z909) Ground circuit in the Manifold Flow Valve 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 (Z909) Ground circuit for an open circuit or high resistance.
      • Perform the POWERTRIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  3. (K601) MFV CONTROL CIRCUIT SHORTED TO VOLTAGE

    1. Turn the ignition off.
    2. Disconnect the Powertrain Control Module (PCM) C2 harness connector.
    3. Turn the ignition on.
    4. Measure the voltage of the (K601) MFV Control circuit in the Manifold Flow Valve harness connector.

      Is there any voltage present?

      Yes 

      • Repair the (K601) MFV Control circuit for a short to voltage.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  4
  4. (K601) MFV CONTROL CIRCUIT SHORTED TO GROUND

    1. Turn the ignition off.
    2. Measure the resistance between ground and the (K601) MFV Control circuit in the Manifold Flow Valve harness connector.

      Is the resistance below 100 Ohms?

      Yes 

      • Repair the (K601) MFV Control circuit for a short to ground.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  5
  5. (K601) MFV CONTROL CIRCUIT OPEN OR HIGH RESISTANCE 
    Fig 4: Checking MFV Control Circuit For Open Or High Resistance
    GC0149797Courtesy of CHRYSLER GROUP, LLC
    1. Measure the resistance of the (K601) MFV Control circuit between the Manifold Flow Valve harness connector and the PCM C2 harness connector.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go To  6

      No 

      • Repair the (K601) MFV Control circuit for an open circuit or high resistance.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  6. MANIFOLD FLOW VALVE

    GC0100022Courtesy of CHRYSLER GROUP, LLC
    1. Connect the PCM C2 harness connector.
    2. Turn the ignition on.
    3. With the scan tool, actuate the Manifold Flow Valve control to the ON (100%) position.
    4. Using a 12-volt test light connected to ground, check the (K601) MFV Control circuit in the Manifold Flow Valve harness connector.
      NOTE:

      The test light should be illuminated and bright with the control actuated ON (100%). Compare the brightness to that of a direct connection to the battery.

    5. With the scan tool, actuate the Manifold Flow Valve control to OFF (0%).
    6. Using a 12-volt test light connected to 12 ground, check the (K601) MFV Control circuit in the Manifold Flow Valve harness connector.
      NOTE:

      The test light should not be illuminated with the control actuated OFF (0%).

      Is the test light illuminated and bright with the control actuated ON and not illuminated with the control actuated OFF?

      Yes 

      • Replace the Manifold Flow Valve in accordance with the service information.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  7
  7. POWERTRAIN CONTROL MODULE (PCM) 
    1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Manifold Flow Valve 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.
    4. Perform any Technical Service Bulletins that may apply.

      Were any problems found?

      Yes 

      • Repair as necessary.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No
