Analog Temperature Sensor
TAN/BLACK sensor lead (in port analog temperature sensor) provides signal for optional
temperature gauge.
An ohms test of the analog temperature sensor (in port cylinder head) would be as follows:
Insert digital or analog ohmmeter test leads into both TAN/BLACK sensor leads. With en-
gine at temperature (F°) indicated, ohm readings should be as indicated ±10%.
