well my clutch safety switch went the other night so i got screwing around under there.. spliced them together and it starts now... I had a check engine light an I plugged in this little green harness that apeared to fit toigether... so now its flashing (im asuming this is an engine code) it flashs 2 long.... then 2 short.... so Im guessing a 22?? anyone know what this code is??

You sure? 22 isn't a possible code for our car's atleast.

22 Ignition pulse system (1983 only)/Vehicle speed sensor or circuit or VLC solenoid valve or circuit. (1984 to 1988 carbureted)

Ok, well unplug your battery for about 1 hour, then it should clear the code, if not, then? I don't know

Thanks... theres somthing about memory codes... so ill chekc an see if that harness is plugged in... I also have an ABS light flashing so i might jsut take the bulbs out if thats possible lol

lol, you should fix taht abs though

For me with my car if ANYTHING isn't perfect it bothers me, like right now ITS BOTHERING me! front left CV needs replacement, need to change ATf fluid, need to clean and detail car, need 2 new front fenders(rust) and repaint front and rear hatch and bumper, and a little bondo and front hood. I am going crazy

Im pretty much the same way... but the cold permits me from actually doing work... ABS will be a fortune to fix i would suspect... an I really dont know what this engine code is so who knows... my trunck vibrates BAAAAD from my subs ( sounds like hell outside

) I want an exhaust system... I want it lowered... its getting sprayed this spring... just a ton of stuff. dealing with it day by day.. I get my full on tuesday if I can pass... yea I got a 92 SS 5 speed at age 16

I am not anal about things being perfect, but I HATE having a CEL on.

For me it's 35 - canister purge solenoid. The thing is a PITA to get to, otherwise I would have fixed it long ago.

I wish I even new what this code was.... Im thinking I have a bad O2 censor cause it floods on start up an stuff... but I REALLY don't know....

Uhh, 22 is knock sensor, very very common code for our cars.

Makes perfect sense... except that from my knowledge the kncok sensor retards timing as to compenate for different combustion errors ... in which "ping" would be produced... car runs great... no ping on hills... no ping any time... Ive had the thing at redline Ive never had it at WOT but damn near.... an it never ever has any problems... so I cant see the knock sensor being bad.... is there away a wire has bin knocked off or somthing lol. The only thing I notice is if u give the car a little shot of gas while on fast idle ( I know not a good idea but i never bring it past 3 grand when its warming up)... it will stay at whatever u rev it to for like about 1 second befor it drops back down.. just enough to notice that it has stuck there for a split second... never does this once warmed up

THe old style of knock sensors crack really really easily, theres a good chance it needs replacing. Both my Legacies needed the knock sensors replced.

so the knock sensor can affect, performance, fuel economy, and im hoping idle a little? All these possible or what? Is the one on the site i provided the new one or old? I need to buy one.

Splinter · Post by **Splinter** » Sat Feb 24, 2007 4:54 am

Yep, all that stuff

and it doesnt even have to throw codes to do so.

No one should be selling the old style anymore, I believe they changed it in 96 or something

whats a knock sensor usually run

IronMonkeyL255 · Post by **IronMonkeyL255** » Sun Feb 25, 2007 2:12 am

Subarugenuineparts has them for just over $50.

I found them under mechanical catalog>electrical>powertrain control>powertrain control>knock sensor
