ECM Code 61 - Page 2 - ZR-1 Net Registry Forums

Ted and Jim,

Thanks for the suggestion. I was looking at the vacuum diagram on page 6A2A-33 of the FSM and drivers side looks to be directly connected to the check valve. I just tried your suggestion and the pump continued to run. I took a snake light and looked under the plenum and found the main line into the tee had come out. I got the line into the tee using a pick-up tool and some long needle nose pliers. The pump now turns on and off about every 30 seconds to a minute, so I must still have a small leak under the plenum. I still will need to pull the plenum but at least now it may clear the code 61??? Need to get the car inspected this month.

Thanks again for the advice, John
