The sender on the thermostat housing is for the computer
The sender on the drivers side rear of the head is for the gauge/dummy light

01 XJ only has 1 sensor, and it is in the thermostat housing. Sensor sends a signal to the PCM. The PCM sends a signal to the gauge.

There is also an Intake Manifold Air Temperature Sensor (IAT), mounted on the intake manifold.
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the density of the air entering the intake manifold based
upon intake manifold temperature. At key-on, a 5–volt power circuit is supplied to the sensor from the PCM. The sensor is grounded at the PCM
through a low-noise, sensor-return circuit. The PCM uses this input to calculate the following:

- Injector pulse-width
[*]Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge temperatures)
The resistance values of the IAT sensor is the same as for the Engine Coolant Temperature (ECT) sensor
