Check Engine Light ~ Won't Pass Smog Test

There are companies that rebuild control modules, this may be a better solution. Search the web for ECU rebuilders

I own a 05 Frontier that recently got a check engine light(code).Dealer said @$400. Go to you purge vent/canister and locate the 2-wire connection going to the actual purge vent solenoid.Establish a good connection and the problem will probably be solved. My understanding is the evaporative canister does not need replacing if unit is 5 lbs or lighter leaving a solenoid if above procedure did not correct. The solenoid is removable and replaceable for much less. This failure is on their cars and trucks and I believe that this is known to all at Nissan but the money is just too good.
