Some times a tiny crack - almost invisible - will occur between the
posts on the sensor, and will result in the light turning on and
blinking. I have had to replace the sensor twice for this problem.

Also try this. Turn on the ignition switch, but DO NOT turn it all the
way to start. The light will come on and blink. Count the blinks to 60
or simply count to 60 using the 1001, 1002, 1003 routine.  Then the
start the engine. The light should go out. It appears that the system
has a test mode in which it does some sampling to test the resistance
between the terminals of the sensor, and if you start the engine before
it is finished, it will sometimes hang and just keep on blinking. This
is just an observation I have made on my own 88 GL.

Finally, be sure your coolant mix is fresh, and is 50/50
water/antifreeze. These little beggars (Vanagons) are sensitive to that.
