Hi there, just joined the forum, first post.
I have a 2007 Mazda Premacy (Mazda 5) Japanese import, live in New Zealand. A few weeks ago I had a couple of incidents where the engine cut out on me, once while I was in drive (automatic transmission) with break on waiting to turn into traffic, and another when I was reversing down my driveway with brake slightly pressed to reduce speed. A day or so after the second incident the CEL came on.
I took the car to a mechanic, he said the code it was giving out was nonsense, reset the code, checked a few things and said the car was fine.
Next day, with CEL off, I went to fill up with petrol. After filling up and starting the engine the CEL came back on. When I got home, I started googling for answers and found lots of posts saying the CEL can come on if the petrol cap is not tightened until it clicks a few times. I had no idea about this so thought this was the likely answer. Since then, even though I now always click three times when screwing the cap on, the CEL still comes on and goes off again intermittently.
Then I read about OBD2 scanners, so I bought one for my iPhone. The code is P2009 which seems to be related to the air intake in the engine. This morning, I filled up with petrol again and the car struggled to start - it has never done this before.
So I'm guessing the mechanic was wrong and that there is something wrong... but does anyone know what? Can a faulty petrol cap cause these sorts of issues? I'm also reading that the car starting rough after a refuel can point to purge solenoid valve.
After paying NZ$92 to have a mechanic tell me there's nothing wrong with my car, I'm nervous to take it in again.
Cheers
Steve
