eratic coolant temp MSnS

[benflynn]

Has anyone had any problems with colant temp readings? Mine fluxuates from 199 to 220+
instantly...maybe this is normal I just thought it seemed to be a little eratic.

I had that with a goofball sensor; It'd jump from 186-192-202-212. When I switched to a Volvo sensor it went away. Probably still increments by four or so.

But if it's going back and forth with no sense,
check the ground and wiring
remove it and check temp/resistance at three points, and run Easytherm again.
