Scan Tool Data List - Engine Controls

SCAN TOOL DATA LIST
Use the Typical Scan Data Values table only after the Powertrain On-Board Diagnostic System Check has been completed, no DTCs were noted and you have determined 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 Typical Scan Data values represent values that would be seen on a normally running engine.

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