I have a 2004 Nissan Pathfinder SE with V6 and 4WD. Service engine light came on. Had it checked at Autozone. Came up as Vapor recovery problem (leak). I smoke tested the system using a home made smoke machine. Smoke poured out of Purge Valve at rear of car. Removed purge valve bracket and purge valve. Purge valve severely corroded and in 2 pieces. Replaced valve. Light still on. I removed vacuum hose at rear of car coming from engine. No vacuum. I removed hose at outlet of vacuum solenoid valve on top of engine. No vacuum. I put 12 volts on terminals o f solenoid valve. Valve opened and there was vacuum at the rear of the car. Checked for voltage on plug to solenoid valve on intake man. 11 volts but valve doesn't open when I plug it back into valve. I bypassed the solenoid valve and I have vacuum at rear of car. I hear air being sucked in at the round vent thing behind the canister with the three large hoses going to it. One hose goes into vehicle frame. The round thing has a white vent on it and that is where air is being sucked in. Any ideas on the vacuum valve on the engines intake or if the vent in rear of car should be sucking air in. I'm lost! Thanks.
have the same problem?
