Can I still drive my car with a P0128 code?
The short answer is yes, you can still drive your car with a P0128 code, but it's not recommended to do so for an extended period. A P0128 code indicates an issue with the engine's coolant temperature not reaching the proper operating temperature, which can lead to decreased fuel efficiency and potential engine damage if left unaddressed.
What is a P0128 Code?
The P0128 code is a diagnostic trouble code that is triggered when the engine's coolant temperature does not reach the proper operating temperature within a specified time frame. This can be caused by a variety of issues, such as a faulty thermostat, a problem with the coolant system, or a malfunctioning engine control module (ECM).
Can I Still Drive with a P0128 Code?
While you can still drive your car with a P0128 code, it's not recommended to do so for an extended period. Driving with this code can lead to the following issues:
- Decreased Fuel Efficiency: The engine's coolant temperature affects the engine's efficiency, and if the temperature doesn't reach the proper operating level, the engine will have to work harder, resulting in decreased fuel efficiency.
- Potential Engine Damage: If the engine doesn't reach the proper operating temperature, it can lead to increased wear and tear on engine components, potentially causing long-term damage.
- Emissions Issues: The P0128 code can also affect the vehicle's emissions, leading to increased pollution and potential issues with passing emissions tests.
It's important to address the underlying cause of the P0128 code as soon as possible to avoid these issues and ensure the long-term health of your vehicle.
How to Diagnose and Fix a P0128 Code
To diagnose and fix a P0128 code, you'll need to use a diagnostic tool to scan the vehicle's computer for any additional trouble codes that may provide more information about the issue. You can then inspect the following components:
- Thermostat: Check if the thermostat is stuck open or closed, preventing the engine from reaching the proper operating temperature.
- Coolant system: Inspect the coolant system for any leaks, blockages, or other issues that may be preventing the engine from reaching the proper temperature.
- Engine control module (ECM): If the ECM is malfunctioning, it may not be able to properly regulate the engine's temperature, leading to the P0128 code.
Once you've identified the underlying cause, you can then proceed to repair or replace the necessary components to resolve the P0128 code and restore your vehicle's proper operation.
How long can I drive with a P0128?
How Long Can You Drive with a P0128 Code? Although it may be possible to drive short distances with code P0128 set, you should get the issue fixed by a professional right away. Doing so will help ensure your vehicle keeps running at its best while also helping to prevent any additional damage.
How serious is P0128 code?
Error code P0128 simply means the coolant temperature is below the ability of the thermostat to regulate. This code may not alert you to the exact nature of the problem, however, it can be an indication of several issues you should check out as soon as possible.
Is it okay to drive with a bad coolant sensor?
Operating a vehicle with a faulty coolant temperature sensor is generally ill-advised, as it can lead to several problems, potentially harming the engine.
What happens if coolant level sensor is bad?
A bad coolant level sensor won't directly cause the engine to overheat. However, it can prevent you from realizing that the coolant fluid has gotten depleted to the point that it can no longer keep the engine cool. Without sufficient coolant fluid, the engine will run hotter than normal.
Can you drive your car if the temperature gauge is not working?
In summary, while you might be able to drive a short distance with a faulty coolant temperature sensor, it's best to avoid doing so until the issue is resolved to prevent further damage to your vehicle.
Will the P0128 code clear itself?
This is referred to as a permanent code. This permanent code will go away on its own after the monitor runs and passes. Until then it will be present but only when read with a scan tool and will not turn the light on. If the problem Is detected again by the computer it will first set a pending code.
What happens when the cylinder head temperature sensor goes bad?
If the sensor sends incorrect temperature data to the ECM, the engine's performance can be affected. Difficulty Starting the Engine: A malfunctioning CHT sensor can disrupt the engine's fuel-air mixture, making it harder for the engine to start.
How do I fix my P0128 engine code?
Check the coolant level: If the level is lower than the minimum, add more coolant and go for a short drive. If the code is still active, you must change the thermostat. Inspect the coolant temperature sensor: The primary coolant temperature sensor is in the cylinder head near the thermostat.
What happens if I unplug coolant temperature sensor?
It's not recommended to unplug the coolant temperature sensor unless necessary for diagnostic purposes, as it can adversely affect engine operation and potentially cause damage if left unplugged for an extended period.
How long can you drive a car with a bad thermostat?
The furthest you can drive an overheating car is about a ΒΌ mile before you risk irreversible engine damage. While some vehicles could still make it as far as 20 miles, we would never recommend driving very far with an overheating engine.
