This past weekend after a long drive in stop and go traffic I came out started my car and found my check engine light on. The light went off the next day but I still pulled the codes and found a P0174. After reviewing threads on this forum I checked both of the PCV lines and found the line from right valve cover to back of throttle body just broke apart in my hand when attempting to remove it. Temorary fixed with piece of hose on both fittings but was able to get new part for $15 at dealer. Car is running like new again.
Jim_V, thanks for reporting your experience! I'm glad to see your SRX is running to your satisfaction again, and please send us a private message if you would ever like us to research future questions for you.
There is no Pcv valve but there is two Pcv lines. I also found that my brake booster hose was so loose it would pop off when touched. Bought the line at dealer and the hose off amazon. 172000 miles runs beautiful. The hose was $13 so I ordered cabin air filter to get free shipping.
