Toyota Paseo speedometer problem

Apologies if this has been asked. 1992 Toyota Paseo: speedometer failed, although odometer continued to work. I got a used instrument cluster, but I still have the same problem. Unfortunate coincidence, or is is possible that the problem is beyond the instrument itself, i.e., is the speedometer actually driven by something other than the cable?

Any thoughts appreciated; my 16-year-old son is about to get his driver's license, and the thought of a new driver with no speedometer thrills him as little as it thrills me. :frown:
 
One thing to try is the transmission (one on the trans itself, and one on the insturment cluster) speed sensors. Take a Ohm meeter to your sensor terminals, and spin the sensor. Your reading should fluctuate between 0 and infinity. Since you tried a new cluster, I'd try the sensor on the transmission itself first. If both sensors are checking out, then you're down to wiring between the Trans, ECU, and Cluster.
 
WHAT was sooo WRONG with a simple CABLE?!?! :devilgrin: :jester:
 
Yeah, that's my thinking...what WAS so wrong with a simple cable? :wink:

Anyway, thanks very much for that information and link. I hope I'll just find a dodgy connection, 'cause I just have this gut feeling that a new sensor (or whatever) will cost a LOT more than a cable (or even the used instrument cluster)! :shocked:

To quote the great lords of Boeing, Lockheed, Airbus, and McDonnel-Douglas............




"Digital is so much more reliable, and is easier to maintian and trouble shoot, and is a much lighter system compared to a comprable analog system."



Seems that car manufacturers have drank the kool-aid. If you want some real fun try chasing down a fault in the generator voltage sense circuit in a Boeing 727. That circuit makes me pray for one that was designed Lucas.
 
Just an update and, thankfully, CLOSURE on the speedo problem. First of all, turns out that both the speedometer and odometer actually do work off the cable! Second, turns out that the speedo/odo in the used cluster I'd bought work just fine, once the speedo/odo unit itself was swapped into the original cluster and everything carefully reconnected. Turns out the original speedometer, with some 236,000+ miles on it, lost its little "clock spring" on the needle.

Worst part of the whole ordeal is that the car has now lost one "badge of honor" in that the replacement speedo/odo only has around 135,000+ showing. :wink:

Thanks to all for help and suggestions!
 
So it actually had a speedo cable? Me thinks that a quick letter and pictures should be sent to AllDataPro.
 
In fairness to them and others, I will note that, between the original instrument cluster and the one I bought (which was reputed to be from a 1993), there was an amazing difference in components. The speedos themselves were identical, and the whole cluster bolted up and plugged in just like the original...but very little worked right.

Maybe AllDataPro was thinking of a newer Paseo? Frankly, even the original factory Paseo manual for 1992 wasn't exactly clear about all this.

No matter; it works now, and the car will be completely driveable once my son and I install new brake lines to the rear wheels (prebent OE lines still available from Toyota at decent prices)!
