Symptoms for Chevrolet Camaro 2000
Important Preliminary Checks Before Starting
Perform Powertrain On Board Diagnostic (OBD) System Check before using the Symptom Tables, and verify all of the following are true:
| • | The PCM and MIL (Service Engine Soon) are operating correctly. |
| • | There are no DTCs stored. |
| • | Ensure that the engine coolant temperature is not above 132°C (270°F). This condition causes the PCM to operate in Engine Coolant Over temperature-Fuel Disabled Mode. While in Engine Coolant Over temperature-Fuel Disabled Mode, the PCM turns fuel off to four cylinders at a time to keep engine temperatures from reaching damaging levels. The customer perceives Engine Coolant Over temperature-Fuel Disabled Mode as a lack of power, miss, or rough idle. If the engine operates in Engine Coolant Over temperature-Fuel Disabled Mode, refer to Engine Overheating in Engine Cooling. |
| • | The scan tool data is within the normal operating range. |
| • | Verify the customers concern, and locate the correct symptom in the table of contents. Inspect the items indicated under that symptom. |
| • | Several of the symptom procedures ask for a thorough Visual/Physical inspection. This step is extremely important - it can lead to correcting a condition without further inspections and can save valuable time. |
| • | If the condition exists as a start and stall, search for DTCs related to the vehicle theft deterrent system. Inspect for improper installation of electrical options such as lights, cellular phones etc. |
| • | Use the following tables when diagnosing a symptom concern. |
| • | If you cannot isolate the condition with the appropriate table, refer to Intermittent Conditions for further diagnosis. |
