Question: Diagnostic Trouble Codes

"i have a 2001 Isuzu Redeo S. I took it in for emissions testing and got the following codes,. P0402 (lcosed valve) and P1404 (excessive flow). How can this be ? Also got Catalic converter Eff. and Oxygen Sensor not ready. Think these are all tided in but I am not sure how.
Thank You, Fran.

P0402 - Exhaust Gas Recirculation Flow Excessive Detected

P1404 - Exhaust gas recirculation (EGR) solenoid - valve closed

They may or may not be related to the other codes. You'll need to check the EGR system proper operation.

The catalyst may need to be replaced.

The o2 sensors may need more time to set readiness or may need to be replaced.
