Back from Autozone with codes ... : )

Hi all,

Well I took your advice and went to AutoZone and got my check engine light tested. It came back with: "P0325 Knock Sensor #1 Circuit Malfunction Bank #1 or #1 Sensor." Anyone know what that means? Advice on what my next step should be? The problem has gotten a lot worse, my poor baby's not doing well at all, then there are some trips she'll act like she's just fine. The light had stayed on solid for the last four days or so, but then went off again on the way home tonight. One thing I forgot to mention, about a week and a half ago I was turning right at a red light. I came to a complete stop, then when I went to turn, it acted like it wasn't in gear at all. (This is an automatic transmission.) I took my foot off the gas, put it back on the break, and when I tried again it slowly moved forward. During this time I hadn't touched the gear shift at all.

Ok, that's my story of woe, any ideas? Thanks! : ) kali

Posted a few days ago ... Hi there,

This is probably on the site somewhere, but I haven't found it yet, so sorry if this is a repeat.

I have a WONDERFUL 1999 Subaru Forrester that I adore, but it's apparently not feeling so well. When I put my foot on the gas it takes a minute to catch up and actually accelerate, and sometimes it shudders as it does. It idles very rough. It's worse in the rain, especially, and when first driving, but doesn't do it all the time. The check engine light is coming on and off, (not blinking,) but sometimes it's on and sometimes not. : / My mechanic said he thought it was the transmission, (at about $3400,) and to take it to the Subaru dealership. I'm planning on doing that, just haven't had time with my work schedule. A friend who's had several Forresters says that it should go away if I have the Fuel Filter serviced? It's only at about 75,000 miles, so it shouldn't be the transmission anytime soon, should it? Also interesting is that my mother has the exact same car, and she has the same issue, mine's just worse right now.

Anyone experienced this? I'm planning on taking it in, but I'd love to have some idea what I'm dealing with. Thanks for reading! : ) Kali

kali,

follow the codes: check the knock sensor wiring for loose connections, shorts, open circuit (cut wire) etc. then, if you find nothing wrong, replace the knock sensor.

So that could be causing all the problems I'm experiencing?

You'll have to excuse my ignorance. I didn't even know I had a knock sensor and I still don't know what it is.

Thanks again, kali

A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock.

If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. That could have caused the problems you were experiencing.
