I fired up the 2001 Forester this morning and found the check engine light shining brightly.

 

I stopped by Checker Auto and had them read the code. It was 0325 Knock Sensor Malfunction Bank 1.

 

Anyone familiar with this? I did a search and didn't find much.

Is this the dreaded gas cap loose code:banghead:?

 

I screwed the cap on tighter till it clicked at Checker and then went about my business.

 

The next time I fired up the Mighty Forester the CEL was gone?.

 

 

I'm confused, can anyone enlighten me?

Time for a Knock sensor.... They go open circuit with temperature change

You can find it just below the throttle body on the cable side ,Take out old one ,clean off block install new knock sensor and torque to 17 lbs/ft

Hope this helps

Just had a knock sensor replaced on my 98 Legacy 2.2 AT. CEL came on and off periodically until I replaced it. No problems or codes since it was replaced. Part was $70 I think and labor was $40. I'll do it myself if i need another one. It's just a bolt on part located under the air box.
