Diagnostic Aids
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- Use the J-35616 Connector Test Adapter Kit for any test that requires probing the PCM harness connector or a component harness connector.
- Inspect for a condition in which the throttle valve may have been held open. For example, ice may have formed in the throttle bore causing the throttle valve not to close. Observe the Freeze Frame/Failure Records.
- 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.
- The scan tool has the ability to operate the throttle control system using the throttle actuator control located in the throttle control menu. This function operates the throttle valve through the entire range in order to determine if the TAC system operates correctly. Additional DTCs may set using this function. Refer to Scan Tool Output Controls for more information.
- For an intermittent condition, refer to Intermittent Conditions .
