how hard is it to change a wheel sensor on a 96 legacy.

i haven't replaced one but i've taken them apart. it's easy... one bolt, unthread it.

 

what's wrong with your brakes?/?

 

 

how hard is it to change a wheel sensor on a 96 legacy.

it's my girlfriends moms car. the abs light comes on sometimes. she's getting it checked at the subaru dealer on tuesday. if it's the sensor i'm going to the junk yard to get one. are wagon sensors the same as sedans.

I've changed a front wheel speed sensor on my own '99 OB. If you're talking about a front one, the '96 is the same as the '99 (I don't know if the rear ones are). It's held to the steering knuckle with one bolt, and 2 more mount the bracket that holds the cable. Other than that, there's a connector.

 

The bolt that holds the sensor can be hard to remove, especially if the car saw winter use in an area that uses road salt, due to rust. Lots of PB Blaster or something similar applied over several days (I'm not kidding) before trying to remove the hardware might help. Unfortunately, the head of the bolt on mine snapped off (the rust was severe), and I had to drill out what was left and carefully remove the remnants. Fortunately, the threads in the knuckle were still in pretty good shape, and I was able to get a replacement bolt, which I applied anti-sieze compound to before mounting the new sensor.

Does the ABS lamp come on when the car is first started (correct operation, if it's for just a few seconds) and then remain on?

Or does it come on initially, go off, and then come back on when the car is driven?

 

You may be able to read any trouble codes yourself; see one of my first posts on USMB:

If you retrieve codes, someone here can probably tell you what they mean.

it comes on while driving. but not everytime.

i'll have to try that. does anyone have a list of what the codes mean.

the garage checked it out and they said the sensors were good. they found a few trouble codes but i don't remember what they were. they did find some wiring that was chewed up by a mouse. they repaired the wiring. they drove it and it seemed fine. we drove around for a while then and it didn't come back on yet. we'll see if it comes back on.

 

they found codes 11, 22, 27, 28. they checked the wheel sensors and the gap and they said it was ok

Rodents apparently are attracted to plastic wire and pipe insulation; I've experienced that problem myself a few times. Hopefully the problem is resolved. If not, the codes seem to indicate the rear left ABS sensor (and wiring, connectors, etc) would be a place to concentrate on.

so pin 6 is for the abs system. how about pins 1-5??

Apparently not all model years have the connector fully pinned. I believe pins 1 and 2 are for air bag diagnosis, 3 and 6 for ABS. My '99 has only those pins. However, according to the info I have, a '95-98 Legacy uses pin 5 for auto trans and the trouble codes are flashed via the AT oil temp lamp. The info also says that those AT codes can be cleared by removing fuse #14 for at least one minute.
