What is the code P0128 on a Dodge Dart?
The Dodge Dart code P0128 is a diagnostic trouble code that indicates an issue with the engine's coolant temperature. This code is triggered when the engine coolant temperature does not reach the expected operating temperature within a specified time frame after the engine is started.
What is the Dodge Dart Code P0128?
The Dodge Dart code P0128 is a diagnostic trouble code that is set when the engine coolant temperature does not reach the expected operating temperature within a specified time after the engine is started. This code is related to the engine's cooling system and can indicate a problem with the thermostat, coolant temperature sensor, or other components in the cooling system.
When the engine is started, the coolant temperature should rise to the normal operating temperature within a certain amount of time. If the coolant temperature does not reach this threshold, the P0128 code will be set by the vehicle's onboard computer, indicating that there is an issue with the engine's cooling system.
Possible Causes of the P0128 Code
There are several potential causes for the Dodge Dart code P0128, including:
- Faulty thermostat: The thermostat is responsible for regulating the flow of coolant through the engine, and a stuck-open or faulty thermostat can prevent the engine from reaching the proper operating temperature.
- Coolant temperature sensor issue: The coolant temperature sensor provides information to the vehicle's computer about the temperature of the coolant. If this sensor is malfunctioning, it can cause the P0128 code to be set.
- Coolant system leaks: If there are any leaks in the coolant system, it can prevent the engine from reaching the proper operating temperature, triggering the P0128 code.
- Blocked or restricted coolant flow: If there is a blockage or restriction in the coolant system, it can prevent the engine from reaching the proper operating temperature, leading to the P0128 code.
If you receive the Dodge Dart code P0128, it's important to have the vehicle diagnosed by a qualified mechanic to determine the root cause of the issue and make the necessary repairs.
