Technical Data - Coolant Temp Sensor Resistance Values
WARNING: This page is about a different car, the 2024 RAM ProMaster EV. However, it is still accessible from the selected car via links, so may be relevant.
Use the specification table below to check the Coolant Temp Sensor. The values in the table show the approximate resistance values for the temperatures given. The actual resistance can vary some from the table. Typically, if the sensor is faulty the resistance value will be noticeably different from the specification in the table.
