My car keeps bringing up the problem code 332 which means insufficient egr flow detected. I don't understand it because the valve is new, the sensor is new, and the pipe going into it is new. I'm guessing the vacuum line going into it is not working. So it must be the line or the solenoid that gives it vacuum. Does anyone know what the specific name of that solenoid is?

 

hmm mines always popped up randomly.. but it came up with o2 sensor codes

 

Just recently 332 has popped on up mine as well along with a 565. I removed the egr, cleaned and tested it all seems fine. My next step is going to be checking/replacing the EGR Vacuum Solenoid. Seeing as the parts are fairly inexpensive and im certain they haven't been replaced since the birth of my vehicle i'm most likely going to replace the egr and vacuum solenoid and hope that it solves the problem.

 

It's called the egr solenoid Also, the port where the valve bolts up could be clogged. Seen that many times.

 

After checking the Purge Valve I noticed the vacuum hoses werent up to par. Cracking and such, noticed a big gapping hole as well, so I replaced the hoses and with wishful thinking was hoping that solved the check engine light problem. Drove to work, no light, no light, bam check engine light. Ill have to do more investigating when I get home.
