CEL. two common codes

[LSiTo5Revo]

if any one has had these codes and has figured out what was setting them off please do enlighten me on what it was. bank 2 sensor 1 and knock sensor.

[green97gt]

how about the actual codes???

its not like you hook up a reader and it just says "knock sensor" or whatever...

could be sensor malfunction, circuit malfunction/high/low/heater/et-frickin-cetera

sounds like you need an upstream O2 sensor, and a knock sensor.

but you gave us no information..so thats just a guess, could be there is an issue with the circuit...etc.

[LSiTo5Revo]

Thats what the codes came up as. my question was...what would set them off. What would be the cause of my knock sensor putting out a code. i cant just assume its bad because the code came up. somthing is setting it off. i cant trouble shoot worth a F*@#. there is no more information to give, that is the information.

[green97gt]

No, its not.

on the same page you posted this thread... about the 3rd sticky is this link.... viewtopic.php?f=11&t=13695 (https://sl-i.net/FORUM/viewtopic.php?f=11&t=13695) or this one http://www.sl-i.net/FORUM/viewtopic.php?f=11&t=6598

open it...use the find function on your browser (hit ctrl + F)

type in knock

hit next, and again, and again, and again there are four knock sensor codes as possibilities.

when you repeat that process typing Bank 2 sensor 1, there are eleven different codes that come up...

believe me, there is more potential info you need.

could be your knock sensor is bad, could be the wiring, could be the ground to the block, could be that the engine is knocking and setting it off, could be any number of reasons.

same with o2 sensors, could be all of the above and more, heaters, dirty, etc etc etc.

knowing WHICH of the several codes it could be leads to correct diagnoses.

i hate to be an ass, but damn dude.

you need to find the Pxxx (eg. P0132) for your codes.
you need to find if the "bank 2 sensor 1" is o2 related or fuel trim related
knock sensor code is usally "knock sensor malfunction" common things are the ground is bad, or sensor is cracked
but you need Pxxx code for us to have a idea were to start

[LSiTo5Revo]

No, its not.

LMFBO!!!! :smt005.

Just like what decke48 said, whenever you scan an OBDII car, it should display a five digit code. It usually begins with "P", then four numbers. Like "P0300" or "P1135".

The information you gave is the computer's description of the codes. But you need the P codes as well.

I don't know what kind of Code Reader your using but every reader I have ever touched from Snap-on to Mactools to cheap-o-autozone readers they all spit out a Pxxxx code.

With some simple google-ing skills I came up with these Pxxxx codes. The O2 sensor code is not a subaru standard OBDII code but what your code reader displayed is what google gave me.

P0050 O2 Sensor Heater Circuit Range/Performance Bank 2 Sensor 1
P0325 Knock Sensor 1 Circuit Malfunction
P0327 Knock Sensor 1 Circuit Malfunction (Low Input)
P0328 Knock Sensor 1 Circuit Malfunction (High Input)
P0330 Knock Sensor 2 Circuit Malfunction
P0332 Knock Sensor 2 Circuit Malfunction (Low Input)
P0333 Knock Sensor 2 Circuit Malfunction (High Input)

So its safe to say you need to replace your knock sensor and o2 sensor.

Did you change your exhaust system? New manifold, cats, bigger pipes? We need more info if you want some help.

2 1/2" cat back.

[chuckthefuk]

change the knock sensor and get a o2 sensor de-fouler / extension to trick the o2 sensor.

The code you claim you got for the O2 sensor is not possible. There is no bank 2 on a Subaru unless you have an H6 and they are different or something.

Knock sensors have a HIGH failure rate on these cars. 90% of the time a knock sensor code is due to the knock sensor failing.

i think this post is about over. the car is gone. thanks for the input tho
