94 SL odometer

While driving my '94 SL, the odometer quit working. The speedometer still
works and there is no SES light or codes stored. After scanning over the
schematic it appears there is only one speed sensor and the signal is
supplied to the PCM, then to the instrument cluster. Question....which is
more likely to have failed, the odometer mechanism or the PCM?

BTW, it stopped at 201008 miles.

Thanks,
T.

since it is a mechanical device, and you still have a speed reading, it's
an odometer issue.

and on the '94, the VSS goes to the IP without going through the PCM.

thanks for the input...

Odo gear on the 1st gen SL's are plastic and usually break after awhile.
Quite expensive laborwise to replace. 93 and 94 were big on this. Not
related to PCM or anything else whatsoever.

Replacing it requres buying a new gear (you can find them if you Google),
removing the dash, cluster gauge and then dissasembling the cluster to
replace the tiny gear. Fun, huh?
:-P

The most popular (and economical) solution is a pad of paper and a pen to
manually write down your mileage.

Been there done that:

Bought the gear for $25 + shipping. It took a couple of hours to get the
cluster out and replace the gear. Not too hard, but you have to really pay
attention to how it went apart to get it back together.
