Diagnostic Aids
- 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 .
