I doubt it would have issues with all codes generated by the car's computer, but some of them are manufacturer-specific. I would not think the knock sensor to be one of those. In fact, it seems to me that a knock sensor problem would cause more of an issue while the car is cold than warm! Maybe I am just not thinking it through well enough though. How about airflow sensor? Input is bypassed from that circuit until the operating cycle reaches a preset temperature.
 
The knock sensor is mounted on top of the engine, just slightly on the right side (looking at the car from the front), and near the back of the block. It is somewhat underneath the intake manifold. It is not overly difficult to access, but it is a tight space - especially plugging it in!
 
Keep us posted with what you discover, please!

Just changed this sensor ($60) on my mother's 2001 Legacy. Very easy to do. Haynes manual has good a description. Make sure to note the orientation of it. I put a long socket extension between the two throttle cables to get to the bolt directly below on the engine block. You'll need a new cable tie unless you figure out how to unlock it. Her car runs better now.

#12 of 406 "Check Engine" light + flashing Cruise Control light = ? by sapphireblue

Nov 05, 2007 (7:13 pm)

Hi all. I have a engine light question re: my 2005 Subaru Outback 2.5i wagon.
 
After driving from MD to NC and back this past weekend (with no problems) ... today I was driving around and, mid-way thru errands, the yellow "Check Engine" light turned on, and the green "Cruise Control" light started to blink on and off. I tried to "turn off" the CC using the handle by the steering wheel (even tho' I wasn't using it), but no luck. And stopping and restarting the car still gives me the error.
 
Any ideas on diagnosis and fix, or should I just take it into my local mechanic? (I'm not super car-fix handy myself.)
 
Thanks,
sapphireblue

The cruise comes on like that to alert you to the CEL that is going on.

Is this something my regular mechanic can diagnose and try to fix? Or do I need to take it to a dealership?
 
And if it is an engine problem (e.g., cylinder issue), is that covered under the 3Y/36000 mile warranties (which I am still under)?
 
Thanks,
sb

Anyone with an OBDII scanner can pull the code. If you are under the 3/36k that is a bumper to bumper warranty which means that whatever is causing it should be covered.

I have a brand new 2008 Subaru Outback with 350 miles. On my way to work yesterday my cruise started flashing & the check engine light came on. I called my dealership but they can't get me in until Monday. Has anyone experienced this issue? Thanks

The CEL + Cruise flasshing just means your have a CEL which could be anything out of about 200 different codes. You'll have to wait and see what the code says when hooked up to an OBDII scanner. Could be something as simple as the gas-cap was not tightened all the way on your last fillup.

#18 of 406 Gas cap not tightened by holte

It was as simple as gas cap not tightened.
They cleared the code a few weeks ago & since I've tightened the gas cap it hasn't come back.
