Code Po449

So I decided to check my spark plugs at 50,000.
They looked good so i decided not to replace.
I put it back together, started my car, and my check engine light was on.

I got a diagnostic and it read code PO449.
I had autozone reset it and it came back on.

Does anyone out there now why this could happen or was it just a coincidence?

Make sure all the connections are good...and no cracks in the tube...before buying parts!

what do you guys think happened.
maybe while pulling the ignition coil i maybe bumped a hose or something.
or messed up the coil itself?? which i took off carfully.

any input would be very appreciated.

Should have nothing to do with your coilpack, I would take it to the dealership, is you car running differently?

When i was taking off the ignition coil to the spark plugs i bumped the vent solenoid valve, do you think that could be cause for the Check engine reading?


As you can see it is right next the the coil and pretty easy to bump.

How hard did you bump it? Just make sure everything is on tight and connected.
