Diagnostic Test

ACTIVE DTC
NOTE: When this DTC is Active the engine speed, torque, and vehicle speed are limited to a Limp in mode.

NOTE: Before continuing visually inspect the throttle blade and bore for any obstructions. Icing of the throttle body may have caused this code to set.

NOTE: Low battery voltage can also cause excessive current draw, in very hot and very cold ambient temperature. Make sure the battery can pass a load test before continuing.

NOTE: Diagnose any 5-Volt Supply, Battery, and TP Sensor DTCs before continuing.
1. Ignition on, engine not running.
2. With a scan tool, select View DTCs.
  Is the DTC Active at this time?
  
  Yes
  - Go to step 2
  No
  - Refer to the INTERMITTENT CONDITION Diagnostic Procedure. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
THROTTLE PLATE INSPECTION
1. Turn the ignition off.
2. Remove the Air Cleaner Assembly from the Throttle Body.
3. Check for any signs of a foreign material (ice or dirt) on the Throttle Plate or in the bore causing the Throttle Plate to stick.
  Were any problems found?
  
  Yes
  - Remove the debris if possible or replace the Throttle Body Assembly. Disconnect the Battery when replacing the Throttle Body Assembly. After installation is complete, use a scan tool and select the ETC RELEARN function.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 3
THROTTLE POSITION WITHIN 2°DEGREES OF DESIRED THROTTLE POSITION
1. Start the engine.
2. Allow the engine to reach normal operating temperature.
3. With a scan tool, monitor the Actual Throttle Position and Desired Throttle Position.
4. Compare the Actual Throttle Position and the Set Point Throttle Position.
  Is the Actual Throttle Position within 2°degrees of the Desired Throttle Position?
  
  Yes
  - Go to step 4
  No
  - Replace the Throttle Body Assembly. Disconnect the Battery when replacing the Throttle Body Assembly. After installation is complete, use a scan tool and select the ETC RELEARN function.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
ETC OPERATION
1. Ignition on, engine not running.
2. With a scan tool, perform the ETC Throttle Follower Test.
  NOTE: It may be necessary to use a mirror to see the throttle blade.
3. Observe the throttle blade.
  NOTE: Make sure the motion of the throttle blade is smooth and that it opens and closes.
  
  Did the ETC motor operate properly?
  
  Yes
  - Refer to the INTERMITTENT CONDITION Diagnostic Procedure. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Replace the Throttle Body Assembly. Disconnect the Battery when replacing the Throttle Body Assembly. After installation is complete, use a scan tool and select the ETC RELEARN function.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
