Default Code 24??

I took my 90 out for a spin yesterday after trying to erase the infl rest light grrrrrr. When I come to a stop, the idle goes way down, the "check engine light" and the "ride control light" come on and the speedo reads "0". After driving for a bit to operating temp, the lights go out, all is well and the speedo works...car runs great. This is very intermitant.

I pulled the codes and have a code 24 "speed sensor". This sensor was replaced about 2 years ago and it might have 5,000 kms on the new one.

Any ideas as to what might be the cause of this code 24 other then the actual sensor itself ? Seems odd that it runs great after it gets to running temp and both lights go out.

As well, If I retrieve the codes and dissconnect the battery...will this erase the codes ? I would like to erase them and see if the code 24 comes back.

Thanks, Tom

Funny. My VSS went out on the drive back from your house! Maybe you live on radioactive land! Jeff knows the #, he just ordered one for me.

Well guys it was the speed sensor. If anyone gets a code 24 chances are it is the speed sensor...this is the second one in 4 years they are not overly durable but works perfectly now.
