John,

Quote from the Service manual:
"During NORMAL engine power operation, (secondary operation disabled) a DTC 61 will set if any vacuum is present at the air inlet valve actuators. When DTC 61 is set, engine speed is limited to 3,000 RPM."

I haven't taken the time to try & review all the diagnostics to see what else besides the solenoind valve, might be involved (secondary vacuum sensor, etc.) Just thought I would tell you what I found regarding a DTC 61 in normal conditions, i.e. no full power operation.

Hope this helps a little bit.
