Circuit Description
During Battery Saver Mode, the powertrain control module (PCM) determines if the throttle plate is returning to the correct de-energized position. If the PCM determines the throttle plate is not at the correct position during battery saver mode, this diagnostic trouble code (DTC) is set.
Conditions for Running the DTC
| • | The ignition is ON and the engine is OFF. |
| • | The ignition voltage is more than 8.5 volts. |
| • | Battery Saver Mode is active. |
Conditions for Setting the DTC
The PCM detects that the commanded and actual throttle positions are not within a calibrated range of each other.
Action Taken When the DTC Sets
The PCM stores conditions which were present when the DTC set as Failure Records only. This information will not be stored as Freeze Frame Records.
Conditions for Clearing the MIL/DTC
| • | The DTC becomes history when the conditions for setting the DTC are no longer present. |
| • | The history DTC clears after 40 malfunction free warm-up cycles. |
| • | The PCM receives a clear code command from the scan tool. |
Diagnostic Aids
If you do not find any trouble, inspect for mechanical conditions or binding that may be temperature related. Components may not move freely in extreme heat or cold due to the presence of contaminants or ice formation.

Does the scan tool indicate throttle position within the specified values? | 10.8-23.2% | Go to Step 6 | Go to Step 4 |
4 | Remove the throttle body assembly. Refer to Throttle Body Assembly Replacement . Did you find any obstructions preventing the throttle blade from returning to the default position? | -- | Go to Step 5 | Go to Step 6 |
5 | Remove the obstruction. Did you complete the repair? | -- | Go to Step 7 | -- |
6 | Replace the throttle body assembly. Refer to Throttle Body Assembly Replacement . Did you complete the replacement? | -- | Go to Step 7 | -- |

Did the DTC fail this ignition? | -- | Go to Step 2 | Go to Step 8 |
Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed? | -- | System OK | ||
