GeneralDisorder Posted October 9, 2018 Share Posted October 9, 2018 Buy a new sensor. Cleaning it is not likely to work. GD 1 Link to comment Share on other sites More sharing options...

Its only a 40 dollar part so ill order it this friday. Im not even sure what a knock sensor does to be honest. But hopefully it will make the car work better?

GeneralDisorder Posted October 9, 2018 Share Posted October 9, 2018 Yes it will make it work a LOT better. Without it you are in limp mode for ignition timing. The knock sensor protects the engine from poor quality gasoline or other causes of detonation. GD Link to comment Share on other sites More sharing options...

GeneralDisorder Posted October 10, 2018 Share Posted October 10, 2018 No - never buy that Chinese junk from autozone. Here's a smokin deal on an OEM JECS sensor: https://www.ebay.com/itm/NEW-UNISIA-JECS-KNOCK-SENSOR-P-N-22060-AA031/332812539727 GD 1 Link to comment Share on other sites More sharing options...

Bigsky Posted October 11, 2018 Author Share Posted October 11, 2018 I think i found a prior post abot where the sensor is, my chilton sucks and doesnt give good descriptions on the location i am hoping this will fix it. I will wrench on it this weekend. According to my manual i have 2 sensors possibly? Link to comment Share on other sites More sharing options...
idosubaru Posted October 13, 2018 Share Posted October 13, 2018 It doesn’t have two knock sensors. it’s really easy. One 12mm bolt and done. 10 minutes if concurrently sipping a beer. find the FSM from Subaru online and use the chiltons for kindling. They’re free and easy to find. Or get more picture grabs online, it’s really easy and will give you the torque value and orientation and location. FSM: ideally you get a 1996 Impreza FSM but any 95-98 legacy or Impreza 2.2 will suffice for the knock sensor job. Link to comment Share on other sites More sharing options...

Same exact code. So i take it there is another problem? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 14, 2018 Share Posted October 14, 2018 Need to check the wiring back to the ECU. Link to comment Share on other sites More sharing options...

This chilton is bullshit. Lol glad i didnt buy it. Ill take a picture of my old knock sensor and maybe yall can tell what was wrong with it. I didnt see any cracks. A bit of corrosion. And ill take a pic of the installed knock sensor tomorrow to double check i installed it correctly. I just did what the prior one was. But maybe that one was installed wrong...?

GeneralDisorder Posted October 14, 2018 Share Posted October 14, 2018 It's just looking for a simple resistance on the single wire. Probably a harness connector problem or melted wire, etc. You can find all the digital factory manuals over on sl-i.net. just google for them.
