Scan Tool Data

NOTE: Information contained in the following tables is typical of readings taken on a vehicle with engine idling at normal operating temperature, throttle closed, transmission in Park or Neutral, system in closed loop status, and all accessories off (except as noted in tables). For additional information, see scan tool owner's manual.
