I need help with this
Maxima 2001
The car has the service engine soon light on with the code p1130 but I don't feel anything wrong with thr car cleared the code ant it comes again.
I tested the valve with voltage and works fine, changed all the hoses, checked the signal to ground from the ecm and all is working fine, cleared the code but it come again immediately

 

Here is a link to the service manual. Follow the diagnostic procedure and hopefully you will find the problem. It starts on page 453.
