RT water temp sensor problem

Postby s2klotus7 » Mon Jun 29, 2009 10:22 am

When I turn the ignition on, why my RT water (coolant) temp will start to count 1,2,3 50,99, 101, etc, etc then stop at 312.00 ??

The value will remain @ 312.00 even the water is dead cold.
I'm using the Bosch water temp formula in the drop down at the dash2 software.

Have you confirmed that it is wired to the DL1 properly? Is the DL1 configured properly? Is the sensor getting power? Good Ground from the sensor?
