DMK Posted October 30, 2019 Share Posted October 30, 2019 My 2000 classic 2.0WRX GT check engine light has been coming on. I've connected the black plugs together and am getting 2 long flashes followed by 2 short flashes. Can anyone confirm if this means that the knock sensor if faulty please? I'm going to take it off and give it a clean anyway now but if the fault code is confirmed I'll probably replace it. Thanks in advance.

stuartie Posted October 30, 2019 Share Posted October 30, 2019 There's a thread in the how to section with all the manual flash codes in it where it tells you long flashes are 10 and short flashes are 1 👍 Quote Link to comment Share on other sites More sharing options...
DMK Posted October 31, 2019 Author Share Posted October 31, 2019 I can't find that thread. But if the flashing means 10+10+1+1 then fault code 22 seems about right. Thank you Quote Link to comment Share on other sites More sharing options...
