Trouble Code: P2102



Throttle Actuator Control Motor Circuit Low Voltage

Possible Causes:



TAC Motor Current is displayed on the scan tool, but the displayed value freezes when the MIL illuminates and the DTC sets.
 
The throttle valve is spring loaded to a slightly open position. The throttle valve should be open approximately 11-15 percent. This is referred to as the rest position.
 
The throttle valve should not be completely closed or open any more than a specified amount.
 
The throttle valve should move open and to the closed position without binding under the normal spring pressure.
 
The throttle should NOT be free to move open or closed WITHOUT spring pressure.
 
For an intermittent condition, refer to Intermittent Conditions .
 

Trouble Code: P2103



Throttle Actuator Control Motor Circuit High Voltage

Possible Causes:



TAC Motor Current is displayed on the scan tool, but the displayed value freezes when the MIL illuminates and the DTC sets.
 
The throttle valve is spring loaded to a slightly open position. The throttle valve should be open approximately 11-15 percent. This is referred to as the rest position.
 
The throttle valve should move open and to the closed position without binding under the normal spring pressure.
 
The throttle should NOT be free to move open or closed WITHOUT spring pressure.
 
For an intermittent condition, refer to Intermittent Conditions .
 

Trouble Code: P2111
