Good To Know
Q: How does this sensor differ from a non-graded sensor? A: A graded sensor is calibrated to maintain tighter tolerances across the operating temperature range, providing more consistent readings for the controller. This helps the Thermo King system respond more accurately to changes in cargo temperature.
Q: Can this sensor be installed without special tools? A: Yes, the sensor typically mounts with the same clip or screw arrangement as the original and connects via the standard weatherpack connector. Verify the connector style matches your harness before installation.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
