hilli182 Posted April 22, 2014 Share Posted April 22, 2014 This morning my car (2000 turbo) cut out on dual carriage way which was handy ....... not As some of you may have read before I've have the judder / stutter problems recently, this morning this happened again but this time the engine just cut out. Engine light came on along with oil and Battery light. I pulled over, shut it off and started up again and carried on, had a couple of stutters but no lights or anything I've just followed this guide http://www.scoobypedia.co.uk/index.php/Knowledge/SubaruTroubleCodeDefinitions and come up with fault code 22. This is apparently "knock sensor" Can anybody point me in the direction of where this is, what it is and what could be wrong with it? Thanks in advance.

hilli182 Posted April 22, 2014 Author Share Posted April 22, 2014 just done a quick google and found this http://bbs.scoobynet.com/general-technical-10/894866-knock-sensor-question.html 5th comment down :) thanks gambit ha Quote Link to comment Share on other sites More sharing options...
Pommy Posted April 22, 2014 Share Posted April 22, 2014 Never had knock myself mate but from what I know about it you will know it when you get it. Did you change your plugs, leads and check coils? (Can't remember if you said in the other post) Could be a faulty sensor by the sounds so worth checking that out. Hopefully someone with some more knowledge will be along shortly.

hilli182 Posted April 22, 2014 Author Share Posted April 22, 2014 i didn't check them to be honest, but the fault code is knock sensor, and from reading the symptoms on various sites it describes the problems I've been having Quote Link to comment Share on other sites More sharing options...

Gambit Posted April 24, 2014 Share Posted April 24, 2014 they just seem to think they own and run everything to do with imprezas lol and judge everyone else's Exactly why myself and many others don't use it. I have a few people on there that I keep in contact and I will pop on for a browse but thats it. It's a shame it's only really just a majority of the members but from speaking with other Scoobie owners their not doing it's reputation any good :( And cheers Martin appreciate the help mate :) Quote Link to comment Share on other sites More sharing options...

I've got a new knock sensor to fit anyways as they are only cheap. What do you think i should look out for with the maf and fuel pump? would a cone filter affect anything that i have going on? Not often you get a garage handing out mechanical know how without charging for it so it is very much appreciated thankyou Quote Link to comment Share on other sites More sharing options...
5heffield 5ubaru 5ervice Posted April 24, 2014 Share Posted April 24, 2014 What type of cone filter are u running , maf sensors are very common on version 5 and can cause erratic idle wont rev above 4500 rpm , holding back , I had one that when u put vehicle under load fuel pump was weak and caused it to misfire and hold back as well , is it noisy and can u here it prime after it cuts out when putting ignition on , are u running a dump valve ??

hilli182 Posted April 25, 2014 Author Share Posted April 25, 2014 It cut out and holds back sometimes at around 4500 tom so sounds similar. Pardon the daft question but what do you mean by hear it prime? It's only cut out once. Other than that it just feels juddery/ stuttering occasionally The car has a k&n "type" cone filter. Blitz bov. Decat down pipe and magnex back box. Other than that it's standard Quote Link to comment Share on other sites More sharing options...
5heffield 5ubaru 5ervice Posted April 25, 2014 Share Posted April 25, 2014 Have had few problems we dump valves could be sticking , blank vac pipe to dump valve and try it pal if not I would see if u could lend a maf off somebody to try mate as they are bout 125 from dealer Sent from my GT-I9305 using Tapatalk Quote Link to comment Share on other sites More sharing options...
hilli182 Posted April 25, 2014 Author Share Posted April 25, 2014 the other symptom i've just noticed / remembered is sometimes when steadily going through the revs, at around 2500 rpm its like it is hesitating / stuttering, usually it will just pull through this and carry on as normal. i will have a look at maf sensor later on see if theres anything wrong with it, if that was faulty would it throw up fault code 22 for the knock though? thats the only thing throwing me if it is the maf or fuel pump etc Quote Link to comment Share on other sites More sharing options...
5heffield 5ubaru 5ervice Posted April 25, 2014 Share Posted April 25, 2014 Knock sensor fault can flash on and off randomly and could be a separate fault to one u experiencing I would block vac pipe on dump valve and give it a run see what happens mate Sent from my GT-I9305 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
hilli182 Posted April 25, 2014 Author Share Posted April 25, 2014 ok no worries thanks lot for that Quote Link to comment Share on other sites More sharing options...
hilli182 Posted April 28, 2014 Author Share Posted April 28, 2014 Update I already had the new sensor before you gave advice Martin so I fitted it but no change like you said so that rules that out I decided to reinstall the original air filter housing rather than the cone last night and so far seems smoother so see how long that lasts. If that doesn't work I will try the vacuum pipe you mentioned. Quote Link to comment Share on other sites More sharing options...
