Post 87 ecm code 15

Hi guys swapped to 87 ecm yesterday and I'm getting low coolant code 15. Does the 87 ecm need a newer coolant sensor installed?

No. I never changed mine on my 85 when ecm upgraded.

Ok thanks. I'll drive it some more and see if it solves itself and if not I replace the sensor.

I disconnected the battery for a while to reset the ecm and it's all good. It was the first start after a new chip so maybe it thought it was something
