Where is the temperature censor in a Peterbilt 378?

In a Peterbilt 378, the temperature sensor is typically located in the engine coolant system, often near the thermostat housing or within the engine block. This sensor monitors the coolant temperature and sends data to the engine's electronic control unit (ECU) to ensure optimal performance and prevent overheating. For precise locations, it's advisable to consult the vehicle's service manual, as configurations can vary based on the engine type and model year.
