"I’m starting to think that instead of having two separate coolant sensors on the engine we need only one as a voltage meter off from that ECU pin?
There Should be a more accurate observation being presented to the driver than a check engine light."

The average driver only wants a binary indicator: Worry. Don't worry.

Average drivers don't head out on the highway with 30-year-old cars. We want Distant Early Warning. The ECU knows what the temp is with granular precision, so we could add a gauge reading in degrees based on the voltage seen on the that wire. A accessory Wagonmeister could offer, you think? Backup to the old hot wire gauge and its oft errant Temp Faker.
