The readings on my digital Cyberdyne gauge have been erratic since last Friday. The change happened literally overnight - the previous day it was fine and normal.

Short version - the temp will read at a normal level around 190-197F and then suddenly plummet from anywhere between 5F and 40F, and then climb back up again by 1F-2F per second until it gets back up to a normal reading. The stock gauge continues to behave normally...

Has anyone else experienced this kind of failure? The gauge is less than a year old (August 2004,) so it's hard to accept that it just up and died. But the only other explanations that I can think of are:

- failing thermostat
- gauge's temp sensor somehow has goop/crap on it and it's fudging the readings

I've been a bit busy driving the car to try to keep a more detailed track of just what circumstances the temp readings dive.

I'm prepared to get another one - I certainly can't keep this one if it's f**ked up. I just want to know if anyone else has seen this kind of prob, or knows someone who has, and what they did?

 

Cyberdyne sensors tend to fail pretty regularly.
Their fuel pressure gauge tends to do this a LOT.
Replacing the sensor should fix the problem.

Hopefully a new sensor won't be too $.


Thanks for the reply.

 

Thought I'd post some follow-up. Is it too soon?

I called Cyberdyne, they said to ship everything back to them. The lady on the phone didn't ask any questions and they shipped a replacement out promptly. 5 years later and no new problems.
