When Monitored and Set Conditions When Monitored: This diagnostic runs when the following conditions are met: •

With the ignition on. 1

•

The ETC Motor Self Learn procedure has been completed.

Set Conditions: •

When the Powertrain Control Module (PCM) detects that the Throttle Body blade is not in the correct position when checked during the closing spring return test for 0.5 seconds.

Default Actions: •

The ETC light will flash.

•

The MIL light will illuminate. Possible Causes

COKING OR BLOCKAGE OF THE THROTTLE PLATE ETC MOTOR/THROTTLE BODY Always perform the PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE before proceeding. (Refer to 28 DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure). 1.

THROTTLE BODY INSPECTION

1. Turn the ignition on. NOTE:

The PCM tests the Throttle Body Assembly by opening and closing the Throttle Body plate before starting the engine.

2. With the scan tool, read DTCs and record on the repair order. Is the DTC active or pending? Yes

•

Go To 2

No

•

Perform the INTERMITTENT CONDITION diagnostic procedure. (Refer to 28 - DTC-Based Diagnostics/ MODULE, Powertrain Control (PCM) - Standard Procedure).

2.

THROTTLE BODY ASSEMBLY 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. 4. Inspect for any signs of coking or a foreign material (ice or dirt) on the Throttle Plate or in the bore causing the Throttle Plate to stick. Turn the ignition on and use the scan tool to actuate the Throttle Plate and check for any sticking. Were any signs of foreign material or scoring of the Throttle Plate or bore found? Yes

No

•

Clean the throttle blade and bore if possible or replace the Throttle Body Assembly in accordance with the Service Information if necessary.

•

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

•

Go To 3 2

3.

CHECK THE THROTTLE BODY ASSEMBLY

1. Disconnect the Throttle Body harness connector. 2. Check the connector for any corroded, pushed out, spread or damaged terminals. Were any problems found? Yes

No

•

Perform the appropriate repair.

•

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

•

Replace the Throttle Body Assembly in accordance with the Service Information. (Refer to 14 - Fuel System/ Fuel Injection/THROTTLE BODY - Removal).

•

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
