Diagnostic Test

WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.

DTC IS ACTIVE
NOTE: Diagnose and repair any related turbocharger solenoid or pressure sensor DTCs before continuing with this test.

NOTE: It may be necessary to test drive the vehicle within the DTC monitoring conditions in order to get this fault to reset.
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 step 2
  No
  - Perform the CHECKING FOR AN INTERMITTENT DTC diagnostic procedure. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
CHECK FOR INTAKE AND EXHAUST SYSTEM RESTRICTIONS
NOTE: Damaged, restricted or poorly connected intake and turbocharger related tubes may cause this DTC to set.
1. Inspect all air intake, crankcase vent and turbocharger related hoses/tubes and connections.
2. Inspect the complete exhaust system for damaged, bent or clogged pipes that can cause exhaust system restrictions and excessive back pressure.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 3
THROTTLE INLET PRESSURE SENSOR CIRCUIT INSPECTION
1. Turn the ignition off.
2. Disconnect the PCM harness connectors.
3. Disconnect the Throttle Inlet Pressure sensor harness connector.
4. Inspect and test each of the sensor circuits between the sensor connector and PCM harness connectors.
  NOTE: Test each circuit for high resistance, a short to ground and a short to voltage.
  
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 4
WASTEGATE AND SOLENOID INSPECTION
NOTE: A seized or sticking Wastegate may cause this DTC to set.
1. Inspect the Wastegate Solenoid, linkage and the Wastegate for proper operation. Refer to the appropriate Service Information.
2. Inspect and test each of the Wastegate solenoid vacuum circuits between the engine, the solenoid and the Wastegate.
3. Inspect and test each of the Wastegate solenoid electrical circuits between the solenoid connector and PCM harness connectors.
  NOTE: Test each electrical circuit for high resistance, a short to ground and a short to voltage.
  
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Repair or replace the Turbocharger in accordance with the Service Information.
  - Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
