I have a 1992 FJ80 that I am trying to get smog tested for the first time (now stationed in CA). Tail pipe emissions are really clean, but it failed because the EGR was not getting a vacuum signal.
I found a problem, the vacuum ports in the throttle body were gunked up. I cleaned them, and now I get vacuum to the EGR VM. I took it in again, but it still fails. I need to get this sorted out ASAP.
What is the driveway procedure for testing EGR vaccum? (How do I know it is fixed?)
i.e. what conditions would activate the EGR?
How do I test the EGR VM and the solenoids?
If anyone could scan the FSM for those few pages, it would be greatly appreciated.
I tried a Chilton, but it was misprinted, the EGR section was omitted so I returned it. I am selling the 92 so I don't want to buy a FSM and shop labor is really expensive in this area.
Thanks,
Jule
