99 - OBD 2 CODE READER INFORMATION

1999 Nissan Pathfinder

Hello, this site is great!

What does it mean after hooking up a code reader when the Freeze Frame section says:

Fuel Sys 1 - OL, not ready CL
Fuel Sys 2 - OL, not ready CL
MAP 29, 2

and the I/M Status (what does I/M stand for?) Says:

EVAP System mon inc
Oxygen Sensor mon inc
Oxygen Sensor Htr inc
EGR system inc

I presume the inc means incomplete. But why? Do I need to turn the engine on. Running for this section?

thanks

Sounds like the battery was disconnected and the car needs to run through a drive cycle. Each car is different so some will cycle sooner then others. Drive the car around for awhile and then run a scan on it again. If the car was driven long enough then you shouldn't get a inc or not ready.
