What is the code P0128 on a 2009 Ford f150?

The P0128 code on a 2009 Ford F150 indicates a problem with the engine coolant temperature. It means that the engine coolant has not reached its required operating temperature within a certain amount of time after starting the truck.
Here are some key points to note about the P0128 code:
– The lack of heat is the most prominent symptom of the P0128 code. When the thermostat fails to bring the engine up to the proper operating temperature, it leads to less or no heat.
– Other symptoms include the check engine light being on, higher than normal idle, decreased fuel economy, and an unusually low temperature gauge.
– To fix the P0128 code, the first step is to get it properly diagnosed to determine the cause of the malfunction in the coolant temperature circuit. Using the live data function of a diagnostic tool can help analyze engine temperatures for a proper diagnosis.
– If you’re not comfortable diagnosing the issue at home, it is recommended to find a certified repair shop to pinpoint the problem and provide an accurate estimate for repairs.
– The cost to fix the P0128 code can vary depending on factors such as location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour for diagnosis and repairs.
It’s important to address this issue immediately as vehicles with this problem may have increased emissions and decreased fuel efficiency. If you need further assistance or have any other questions, feel free to ask!

Is P0128 a thermostat or sensor?

While there is a small chance that there is an issue with the running temperature of your engine, by far the most common issue with trouble code P0128 is a faulty thermostat. The exact location of the thermostat and issues related to a damaged thermostat may vary depending on your vehicle.

How do I fix a P0128 code?

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.

Will low coolant cause P0128?

So when that thermostat remains fully open that is going to provide maximum Cooling. And potentially not allow the engine to reach its operating temperature at all which is in turn what triggers fault

How do you unstick an engine thermostat?

This is an easy problem to solve yourself by simply removing the plastic outer casing and, with a very soft brush, delicately brushing off its coil and contact surfaces. It is most effective to clean the thermostat first at its lowest setting, then again at its highest setting.

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

How to Know if Your Temperature Sensor is Faulty

1. The equipment is experiencing intermittent thermocouple failure.
2. Instruments are showing “Open Circuit”.
3. The temperature gauge on your equipment isn’t reading accurately.
4. The equipment stops heating or cooling properly.
5. The equipment is overheating.

Can I drive with P0128 code?

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 to fix coolant temperature below thermostat regulating temperature?

If the level is under the minimum requirement, add more coolant so the level comes up to the maximum level. Take the car for a short drive and see if the same P0128 fault code comes up. If topping off the coolant doesn’t help, the thermostat should be the next thing to replace.

Where is the thermostat sensor located?

Most home thermostats are located in a central location in the home, like a hallway so that the temperature sensed is an average of the total temperature in the home. In most cases the temperature sensor is inside the thermostat but not always.

Where is the coolant temperature sensor located?

Where is the Coolant Temperature Sensor located? The coolant temperature sensor will be located directly behind the coolant pipe. In most modern cars and vehicles, this is present behind the right cylinder head that is located right underneath the air intake pipe.

Will code P0128 reset 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.
