Question about Subaru Legacy

1 Answer

Speed sensor grommet stuck in transmission mount...installing new speed sensor (finally), but the rubber grommet and metal washer on the end are stuck in the slot, and I don't want to do any more prying to get them out because I REALLY don't want to mess up the transmission. My question: as an interim measure, can I take the new grommet & washer off the new sensor and install it with the old grommet & washer (grommet is a little beat up) still in? I need to get this car home tomorrow--I'm more than a thousand miles from home and I can't stay here any longer. Please help? Thanks.

If the old one is not damaged, then just put the new sensor in itself. Should be good enough to get you home.

    Thanks for the quick reply.
    The old rubber grommet has had it, which is probably why it's stuck in there. Melted, almost, or something. I'm hoping that doesn't have anything to do with why the old sensor was throwing codes at me. Still okay to put new one in? Thanks for the clarification. I've been working on this issue all week...no sleep...lol.

    If you can get your hands on an ohmmeter, test the old sensor. If sensor has a good resistance reading, then it is good and the grommet is the problem. If there is no reading, or very low reading, then sensor is the problem. Grommets don't usually cause problems. It's usually the sensor that give you the most problems. An ohmmeter would be your best bet. Just put on ohm setting, put one probe on each metal contact pin and check the reading. You can get the cheap ones for just a couple dollars that seem to work just fine.

  • the_antirazo May 29, 2010

    Thank you...will try to get an ohmmeter and check. But there is only one pin on the connector between the speedo cable and the sensor. Do I test between the pin and the sensor receptacle? Thanks!

  • Nate Stansfield
    Nate Stansfield May 29, 2010

    If there is only one sensor, then check between the connection point and the tip of the senor itself. I would personally replace the sensor itself anyways.

  • the_antirazo May 29, 2010

    Yeah, I'm going ahead and replacing it anyway, as you say. From the very few illustrations I can find online, it seems that more threads are showing once I've tightened the b nut than there are supposed to be, but it feels tight and I don't want to crack the plastic nut. Just in your opinion as someone way more experienced, do you think I can get away with this? Are they supposed to tighten all the way down?

  • Nate Stansfield
    Nate Stansfield May 29, 2010

    It should tighten down so that the sensor will not move. If the sensor will move around in the grommet, then you won't get correct readings. What year, make, model and engine liter size do you have?

  • the_antirazo May 29, 2010

    It's a 1990 Subaru Legacy wagon, 2.2 L engine...

  • Nate Stansfield
    Nate Stansfield May 29, 2010

    If my memory serves me correctly, this should have a pigtail type wiring with two wires that twist around each other. Then at the plug-in itself, should have two terminals on it where you could test with ohmmeter. There may be two speed sensors in this model. Some do, not quite sure if yours does.

    You can see the manual here:

  • the_antirazo May 30, 2010

    Thanks for the picture ref. I managed to get the old grommet and washer out, and installed brand new sensor w/grommet and washer. CEL still came on, still giving me speed sensor code (this is the only speed sensor my car has). Could it be the speedo cable is bad? Could excessive wheel vibration cause this? (last professional I took it to said wheels needed to be balanced).

  • Nate Stansfield
    Nate Stansfield May 30, 2010

    A bad cable could do this. It would be a good idea to test the cable and sensor with an ohmeter on the plug-in side. If you already had a cel for the other sensor, then the computer should have been reset with scan tool after new sensor is replaced to reset the computer. Vibrations could cause this if they are severe. Light vibrations would not cause this.

I had my car analyzed this morning for the check engine light's on. and result was speed sensor... i want to replace it myself but i don't know where the sensor is..


Hello Edison....
The speed sensor on the 3.5 litre engine in your Malibu is is located on the transmission final drive housing. This is the end of the trans. that the passenger side axle comes out of. It has a 2 wire connector on it. It can be accessed from undeneath the car...Attached is an image of a new sensor. Note the rubber 0-ring. Apply a thin coat of engine oil on it when you install. To not over-tighten. For best performance, replace with an AC Delco brand sensor, estimated cost. $25 dollars.
Hope this will FixYa...seeya next time, and good luck with the Malibu :)

How hard or expensive is it to change a speed sensor in a 1991 Honda Prelude SI?


The speedometer sensor is located on the top of the transmission. It is held on by one bolt. Remove the bolt and gently pull and turn the speedometer sensor and the whole assembly will come out of your transmission.


Park your Honda Prelude on a level surface, activate the emergency brake and place blocks behind the back tires for safety. Disconnect the negative battery cable with a terminal puller.

Raise the vehicle on the side of the wheel speed sensor's location. Remove the wheel and tire assemblies.

Disconnect the sensor electrical connection from the wiring harness.

Take note of the connection location for the sensor retainers, grommets and clips. You will need to know this information for the installation process.

Start at the connector end of the sensor cable and remove grommets, clips and retainers in order to free the harness.

Unscrew the sensor mounting bolt and remove the sensor from the differential housing.

Install the new speed sensor by reversing the removal process. Loosely secure the sensor and sensor harness connection in place, taking precaution to keep the harness from twisting or bending. Once in place, torque the sensor mounting bolt to 16 foot pounds (22 Nm). Tighten any bracket bolts to 84 inch pounds (10 Nm).

Lower the vehicle safely and reconnect the negative battery cable. Refer to your owner's manual to perform an ABS system check to confirm that you installed the sensor properly.

Rear speed sensor removal front wheel drive


Don't remove the speed sensor from the hub wiht everything mounted on the car - you're almost guaranteed to destroy them (happened to me on my A4). Rolling friction while you're driving heats the hubs and basically seizes the sensors into the hubs. Better way to do it is to remove the rear seat bottom cushion (it just pops off if you pull up firmly from the front, bottom edge of it), and unplug the speed sensors from the main harness. There's a large wire bundle running across the car under the seat, and the speed sensors are plugged into it.

After you remove the cushion, you'll see right near the door jambs on each side (under the seat) a 2" or so diameter black foam or rubber grommet with a wire running through it. That's the speed sensor wire. Trace it back to the bundle and you'll see where it's plugged in. Unplug it, pop the grommet, then get under the car and follow the wire from the sensor in the hub forward. You'll see it runs under a bracket on the lower A-arm, which you can remove with a 9mm socket (2 nuts) and goes up through the floor of the car just inside the jack rail on the bottom, again through a black rubber grommet. Pop that grommet down and out as well, and you'll be able to feed the wire and plug down from the under-seat area and out the bottom of the car. Then you'll be able to move the suspension however you need to, without fear of damaging anything to do with the sensors.
