The one solenoid on my car is (was) there for the fuel tank vapors. It is connected to the canister on one side and to the intake on the other. The canister itself is also connected to the fuel tank and the atmosphere valve and filter.

So, the Euro NBs do have the six-wire EGR valve, but they do not have an EGR pressure sensor?

I'd have to check the number of wires on my car, but I'm pretty sure it has 6 wires.

Could well be an EGR pressure sensor elsewhere in addition to the Barr sensor

anyways, it references the exhaust flow back into the intake.

Great diagram...Thanks.

Correct. We also don't have the VTCS.
