I have a 97 honda accord 2.2 vtec and the check engine light is on and I had the code pulled and I either have failed egr valve or theegr solenoid is bad how do I diagnose which one it is. Also I checked the lines and they are not plugged

 

What code? It could be failed EGR, blocked EGR manifold ports, or loss of vacuum to actuate the EGR.

good luck

 

Auto Zone pulled the code and the Definition: EGR system fault (Exhaust gas Recirculation)
Explanation: The ECM has detected too little flow on the EGR system. Probable Causes: 1 blocked passage on the EGR system,2 failed EGR valve,3 EGR solenoid faulty, The hoses connected to the EGR are not pluged so I'm down to the other possible causes I just need to know how to cheek the parts thank you

 

The ports on the manifold are the likely clogged. Google t2t013.pdf and the last two pages show the steps for a 94-97 accord.

Good Luck.
