P0443 on '96 Maxima

No your problem is the purge control valve circuit. There are two right along side each other mounted to a metal bracket. stand in front of the car with hood open look down to the right side of the valve cover. you will notice they are kind of hidden right beside the valve cover. one is called a sekenoid circuit and the other is called a purge valve. the one bolted to the left is the circuit it is your problem. the one on the left is upside down with two vacuam hoses at the bottom and one vacuam hose on the top and a connector. unplug it and take it off. connect a hot wire to the one prong and a ground wire to the other prong and run the one to positive battery post and the other to the neg post on your battery. if the solenoid clicks each time you touch the post it is good if no click it is bad. you can check the other one the same way. mine was bad and would not click. I checked the new one before I put it on and bam it clicked. reset your check engine light when your done and it will stay out. this is the p0443 code problem let me know. I grant you if you do this it will solve your problem.

nope. all the test does is look at the status of the monitors. does not test anything. besides, your code has a 3 trip code set. that means that the test has to fail at least 3 times before a code is set. this means your problem ocurred at least 3 days prior to your test. Roy
