PID Value Charts: Notes

Ensure following conditions are met before comparing scan tool data to typical data value found in appropriate PID value chart:

• Engine is idling unless checking a value at a specified RPM.
• Throttle is closed unless checking a value at a specified RPM.
• Vehicle is in Park or Neutral.
• Vehicle is operating in closed loop.
• Vehicle accessories are turned off.

Compare actual PID values on scan tool to PID values found in appropriate PID value chart.
