Default 2001 Forester Knock Sensor again - 05-07-2007 , 09:45 AM






The guy at autozone tested my car to see why the engine light was on. he
said it showed the knock sensor. So I replaced it for $75. But the light
has not gone off. I am not happy with this.

Anyone have experience with this? Any reason why the light would not go
off? Perhaps the wire is bad or something!?



Thanks for tips.

What octane fuel you running? You might try a higher octane rating if
possible. . . . and yes, a bad wire is always a possibility.

I'm sure there are more things to check on your rig.

Did you clear the computer? Always good to reset it after replacing a
sensor....

I tried the high octane before I replaced the sensor. No luck. Does it
require a specific torque setting? Maybe I need to buy a quality torque
wrench?

I did not. Typicaly though when the active codes clear the engine light
goes off. The light does not light over stored codes. But I'll bite the
bullett and buy a code thingy today I suppose...

Some of the auto parts stores (in the USA) will read/reset them for free.
Disconnecting the battery for a few minutes will reset it too.

I have 01 Forester. Experienced same problem several months ago. The car had
~63K miles back then. Took it to dealer...they fixed it - and it never
happened again (so far).
