Scan Data - Typical Data Values
The "Scan Data" listed in the table may be used for comparison, after completing the Diagnostic Circuit Check and finding the on-board diagnostics functioning properly and no trouble codes displayed. The "Typical Values" are an average of display values recorded from normally operating vehicles and are intended to represent what a normally functioning system would typically display.
NOTE:
All readings at idle, with upper radiator hose hot, closed throttle, PARK or Neutral, Closed Loop, and all accessories OFF.
