Coolant warning light

Still having issues with my coolant sensor. Warning light comes on after 7or 8 seconds after startup. Level is fine and I just changed the sensor for a new oem one.
Any ideas?

Have you checked the plug that connects to the sensor? It's really common for corrosion or frayed or broken wires causing intermittent connections to the sensor.
Put a loop of wire in the Plugs holes to short it out, turn on ignition and see if the panel light is still on, if it's not waggle the loom where it enters the plug and see if you get a warning indication light.
Make sure you clean the connectors on the plug as well, can be very messy and cause issues even with a new sensor.

Thanks. I'll give this a try!
