What does error code P0128 mean on a Dodge Grand Caravan?

The error code P0128 on a Dodge Grand Caravan indicates a problem with the engine coolant temperature. Specifically, it means that the engine coolant temperature has not reached its required operating temperature within a certain amount of time after starting the vehicle.
The lack of heat is the most prominent symptom of the P0128 trouble code in the Dodge Caravan. When the thermostat doesn’t bring the engine up to the proper operating temperature, it means that the coolant going through the heater core isn’t as hot.
The P0128 code is typically caused by a faulty thermostat or a leaking cooling system. The thermostat’s role is to prevent the coolant from entering the radiator until the engine reaches the right temperature. A malfunctioning thermostat can result in the engine not reaching the optimal temperature within the set time, leading to increased emissions and decreased fuel efficiency.
Other possible causes of the P0128 code include a faulty coolant temperature sensor, damaged wiring to the coolant temperature sensor circuit, low coolant level, a bad radiator fan or water pump, or an inaccurate engine coolant temperature sensor (ECT sensor).
To fix the P0128 code, it is important to diagnose the root cause of the problem. This may involve checking the coolant level, inspecting the thermostat for any issues, and ensuring that the cooling system is functioning properly. In some cases, replacing the thermostat or reprogramming the engine control module (PCM) may be necessary .
It is recommended to address the P0128 code immediately to prevent further issues and ensure optimal engine performance.

How do I fix my Chevy P0128 code?

1. Check the coolant level: If the level is lower than the minimum, add more coolant and go for a short drive.
2. Inspect the coolant temperature sensor: The primary coolant temperature sensor is in the cylinder head near the thermostat.

Is P0128 a thermostat or sensor?

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.

Where is the thermostat sensor located?

The AC sensor on your thermostat is located near the evaporator coils. Indoor air moving toward the return vents passes by the sensor and coils. In turn, the sensor reads the temperature and checks if it matches what you’ve set on the thermostat.

What causes a coolant temperature sensor to go bad?

Causes of Coolant Temperature Sensor Problems
The most common cause is a build-up of deposits on the sensor, which can interfere with its ability to accurately measure the coolant temperature. Another possibility is that the coolant level is too low, which can cause the sensor to overheat and fail.

Is p0128 a thermostat or sensor?
