What Are Some Causes of a P0128 Code? Error code P0128 indicates that your engine coolant temperature is below the thermostat regulating temperature. This means that your Engine Control Module (ECM) or Powertrain Control Module (PCM) has recognized that your engine is running cooler than it’s supposed to.

What happens when a coolant temperature sensor goes bad?

If the coolant temperature sensor malfunctions, it could cause your car engine to get overheated. While sometimes a faulty sensor sends a permanent cold signal to the engine, it can also send a permanent hot signal.

How do I know if my Dodge Caravan thermostat is bad?

Here are four signs that it may need to be replaced.

1. High Temperature. One of the first signs that your thermostat may need replacement is how high the temperature inside gets.
2. Cold Engine.
3. Temperature Gauge Issues.
4. Coolant Level Issues.

How do I know if my thermostat or sensor is bad?

1. Fuel economy is poor. Poor fuel economy is one of the first signs of a problem with the coolant temperature sensor.
2. The engine is spewing black smoke.
3. Engine is overheating.
4. The Check Engine Light illuminates.

Where is the thermostat sensor located?

The temperature sensor on a thermostat is typically located inside the thermostat itself. The temperature sensor is usually a thermistor, which is a device that measures temperature by converting a temperature change into an electrical signal.
