Scan Tool Data List - Powertrain System

Diagnostic Chart:

The Engine Scan Tool Data List contains all of the engine related parameters that are available on the scan tool. The list is arranged in alphabetical order.

Use the Engine Scan Tool Data List only after verifying the following:
^ The Power train on-board Diagnostic System Check is completed.
^ No Diagnostic Trouble Codes (DTCs) are present.
^ The on-board diagnostics are functioning properly.

Scan tool values from a properly running engine may be used for comparison with the engine you are diagnosing. The Engine Scan Tool Data List represents values that would be seen on a normally running engine.

IMPORTANT: A scan tool that displays faulty data should not be used. The scan tool problem should be reported to the manufacturer. The use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.

Only the parameters listed below are referenced in this service manual for use in diagnosis. If all values are within the typical range described below, refer to Symptoms for diagnosis.
