Hi all, the speedo on my TJ gave up the Ghost the other day, electronic, mega short SYE with tone ring and sensor set up, all other gauges are ok, anyone got any ideas.
have read stuff from check out dash connection to transfer case will start making noise soon and will blow up?? the latter being a little far fetched I think.
But if anyone can lessen the gap between the examples given I'll be glad to listen

cheers

There is a self check for the instrument panel. Hold the speedo reset button in and turn on the key, each instrument should move through its full range in turn. That will tell you if the speedo is working.

cheers mate will try that tomorrow and let ya know what happens

Greg

well , did the check thing today all gauges went through their range and all looked good, even speedo, So looks to me like the speed sensor is dodgey , is there more than one I should be looking for ??? or just the one on the end of transfer case ???

cheers

check the voltage out of the sensor on the sye and the connections too bud. From memory theres nothing else between there and the speedo in the way of sensors.

cheers Mark, thought it wouldn't be long before you and your impecible jeep knowledge showed up
thanks heaps

wouldnt go quite that far bud

hey while you're there mate how much float should a TJ rear axle have, mine seems to be about 2--3 mills in and out, is that about normal ???

and there's not another one elsewhere sending back to ECU??

axle: Ive never had any movement. RJ did and replaced the bearings. Cant say wether its normal or not.

ECU: I thought it went through the ecu to the speedo. If you can wait Ill pull out my TJ FSM tomorrow and check.

cheers dude will wait to hear from ya then

Speedo sorted now got a new mega short SYE speed sensor from Hoppy and it's all good, just need the truspeed calibrator and I'll be super happy
