My afterrun typically would never come on unless the weather was
warm-to-hot. I did the shorted-leads test, and that seemed to check
out OK. Eventually the afterrun became undependable even in hot
weather and often didn't work when expected. Last month, when I
finally replaced the sensor, I found that one of the spade connectors
had never been properly pushed onto the sensor terminal
(inadvertantly, it had been pushed aside--inside its rubber boot.)
That sensor terminal was also well-corroded--I guess there might have
been enough accidental contact from time-to-time for the system to
trigger, but it eventually stopped. I've installed the new sensor,
taking care to make proper connections. However the system still
seems to need (as Ben says) to be "really heat soaked" and have
fairly warm weather in order to come on.
