Would a 2se gasoline 1986 camry use a electronic vacuum regulating valve or a high altitude compensator? Chilton's only shows those two in diagrams of diesel engines.

My hunch is they should not have been on my car.

Unlikely. Those both sound like carburetor (gas) or mechanical injection (diesel) items. Your engine is EFI.

There are a number of VSV (vacuum switching valves) that do perform various operations on your engine though. (AC idle-up, evap system control, EGR control, etc.)

That what I was thinking. I see it does have a couple vsv.....
  • The camry I have one, but the more I learned about it, the less likely it seems it belongs there.
  • Its bolted to valve cover, above spark plug closest to driver side. The two wires broke off.

That looks original to me. Sounds like Toyota just changed their terminology between the gen1 and gen2 Camry. I don't know what that regulates, but that unit will either pass air/vacuum or not depending on the energized state of the solenoid in the body of that valve.

Thanks Charlie.
The piece isn't in diagram for EGR system....perhaps it was before the computer compensated for high altitude.....the 86 also has a cold start valve/injector and I think subsequent fuel injected toyotas had that function taken over by ecu

Altitude compensation shouldn't be needed with a vane airflow meter. That could also be for evaporative emissions control, AC idle-up or maybe some other function.

Thanks Charlie....I'm glad you're still here sharing your knowledge.
