    re-occuring knock sensor problem

    in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVX

    Posted

    I had the same problem. I replaced the sensor. The check engine light came on again (codes: misfire, and fuel sending unit). Anyway, some rattling and knocking started, and got louder. Turns out my timing belt pulleys and tensioner were wobbling and the belt was making a racket against the cover. I'm having the pulleys, tensioner and timing belt replaced (and the water pump, wobbling too). The wierd thing is that all that racket didn't make the check engine light come on. Go figure! But at 180,000k I figure now's a good time to do the timing belt.

    Okay, thanks. Funny the shop even gave me the number of the code. For fuel sending unit, the fuel gauge thing at the tank. I could be mistaken. I have noticed that whenever the fuel gauge needle takes a sudden dive to "empty", the check engine light comes on shortly after that. Then, when I put some gas in the tank and the needle comes back to life and settles at its correct position, the check engine turns off. :confused:

     

    er um....

     

    You wont get a code for a fuel sender. Its not even part of the ECU circuit.

    Subarus have notorously bad fuel senders that can usually be made better with Techron fuel additive.

    Personally i would say unless the sender is dead, do the techron thing.

    I have never bought major parts off ebay that were not OE. Luckily its something thats easy to get to.

    Thanks! I forgot to mention.... I took it into the shop because the check engine light came on. Two codes: misfire, and fuel sending unit. New wires took care of the misfire. Subaru wanted $130 for the sending unit. I figured I'd go ahead and change the pump and strainer while I'm in there. Subaru wanted $445 for the pump. Wow. I hope I didn't do the wrong thing by buying the pump, strainer AND strainer for around $120 altogether off ebay. I got the Bosch pump and OEM Subaru sending unit.

     

     

    Hey.....another Houstonian :)

     

    Do you know if the shop put in a subaru thermostat? If not, you still may have some issues. Don't ask me why, but Subaru engines act weird if they don't have a subaru thermostat in them.

     

    BTW, you may want to check out the texas forum on http://forums.nasioc.com/forums

     

    There are local get togethers every week, and state meets at times throughout the year.

     

    If you still have problems with the car, let me know, I could take a look at it.

    For those of you keeping track of this.... According to the shop, it's the thermostat. The shop INSTALLED the thermostat because there was NO thermostat to begin with. But I don't see how the lack of a thermostat would make the needle suddenly drop. Maybe not enough in the pressure? And why would it go up and then down... I have a feeling I'll need to replace the sensor anyway.

     

     

    My 98 Forester's temp gauge tends to drop down to the bottom for no apparent reason. Today I was doing 70 on the highway, and the temp needle just plunked to the bottom of the gauge. It had been holding steady about half way up for several minutes. What's the problem? or is this normal? It was was well over 32F at the time. Thanks!
