bobbing temp gauge

Postby grimey » Thu Sep 15, 2011 5:17 pm

so Lately im getting some weird readings from my VO temp gauge. Ill be driving along and all of a sudden my temp will drop down to around 120F then the gauge will bounce a bit maybe itll go back up to 160F or 140F. it seems really strange. anyone experience a bobbing temp guage?

Is there anyway my temp could be fluctuating that fast? seems like my gauge went bad.

How fast? If its electronic, it could be a bad ground or positive wire, bad sender, or bad guage.

heres a quick vid i took:

in the video its not really bobbing, but sometimes it goes back and for pretty quick and sporatic, like wiggling almost.

its an electronic guage ive checked the wires and wiggled em, no luck. im gonna swap in another guage and see if thats it.

but if its accurate what could cause temp changes like that?

Its probably not accurate. Only the things I listed above could cause it to jump in <1 sec.
