PID Value Charts: Notes
Ensure following conditions are met before comparing scan tool data to typical data value found in appropriate PID value table:
- 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.
