Diagnostic Test

  1. 1) ACTIVE DTC 
    NOTE: Diagnose any TP Sensor or 5 Volt Supply DTCs before continuing.

    Turn the ignition on.

    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 can result in personal injury or death.

    With the scan tool, select View DTCs.

    Is the status Active for this DTC? 

    Yes

    No 

    1. Refer to *CHECKING FOR AN INTERMITTENT CONDITION diagnostic procedure.
  2. 2) THROTTLE PLATE INSPECTION 

    Turn the ignition off.

    Remove the air cleaner assembly.

    Check for any signs of a foreign material (ice or dirt) on the throttle plate or in the throttle bore that can cause the throttle plate to stick or not open.

    Attempt to manually open the throttle plate. Use an appropriate tool that will not damage or mar the throttle body.

    Were any problems found? 

    Yes
