Can I drive my car with a P0128 code?

Can I drive my vehicle with a P0128 trouble code and illuminated CEL? You may drive your vehicle with a P0128 trouble code. You will not notice any issue except for maybe the temperature gauge never reaching normal levels, and possibly the Check Engine light being illuminated.

How much does it cost to fix P0128?

How much will it cost to fix? Running a diagnostic for a P0128 will cost around one hour of labor, which may run you between $75 and $150. If you need to replace the thermostat, the total cost for parts and labor will be around $470 to $505.

How do I get rid of code P0128?

Can low coolant cause a P0128 code?

Low engine coolant can alter the engine running temperature enough to signal trouble code P0128. Your intake air temperature sensor, coolant temperature sensor and coolant fan could also signal this trouble code, so these should be inspected after you look over your thermostat and coolant level.

What causes a po128 code?

There are two main causes for P0128: The most common cause is an engine coolant thermostat that has stuck open or is opening prematurely. The next cause is a problem with the engine coolant temperature sensor or the wiring associated with the sensor.

How is P0128 diagnosed?

The most common cause for P0128 is the engine coolant thermostat is stuck open. A simple way to diagnose this is to feel the radiator hose and monitor how hot the temperature of the coolant is when it starts flowing through the radiator hose.

Can thermostat trigger Check Engine light?

the most noticeable issues occur when the thermostat gets stuck in either the open or closed position. a malfunction can result in a trouble code, generated by the engine’s computer, which can turn on your check engine light.

What does ECT sensor do?

A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.

What happens if engine runs too cold?

If you run your engine cold all the time, you’ll most likely experience increased fuel consumption across the board. Additionally, you’ll find higher amounts of carbon buildup at various parts of the engine. The most damaging effect of feeding a fuel-rich mixture to the engine is excess fuel reaching the exhaust.

How do I know if my car needs a thermostat?

If you notice any of these telltale signs, your car may need a new thermostat:
  1. The temperature gauge says the engine is very hot or cold.
  2. The engine tends to overheat.
  3. The temperature in your car often changes drastically.
  4. You have coolant leaking under the car.

How do I test my engine thermostat?

Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.

How do you tell if you have a stuck thermostat?

Look to see if the coolant is swirling/flowing immediately — that means the thermostat’s stuck open. If the coolant doesn’t flow after 10 minutes or so and continues to be stagnant after the temperature gauge indicates it’s hot, the thermostat’s likely stuck closed.

How do I know if my car’s thermostat is bad?

One of the first things you will notice is the temperature gauge is higher than normal. It may even start to fluctuate frequently. If you notice the gauge is hovering ¾ of the way from the top, then your thermostat is experiencing damage in the form of overheating. This can soon lead to your engine and car overheating.

How often should you change the thermostat in your car?

10 years
However, most car experts recommend car thermostat replacement after 10 years. However, this is an optimistic number. Thermostats are more likely to stop working much earlier than a decade. Some factors that induce an early thermostat failure include harsh weather, rough driving, bad engine or thermostat parts.

How much does thermostat replacement in car cost?

Answer provided by. Unfortunately, thermostats play an essential role in your car. So fixing a car thermostat will usually cost somewhere in the range of $200 to $300.

Is it good to remove thermostat from car?

Its work is to block the flow of coolant to the radiator until the engine has warmed up to optimum temperature, after which the thermostat then opens up to allow free flow of coolant. Removing the thermostat from any car is NOT a good idea. It simply complicates issues and makes things worse for your car.

What is the best temperature for a car thermostat?

between 195 degrees and 220 degrees
Normal Temperature engine temperature gauge

Most experts agree that your engine should run between 195 degrees and 220 degrees. In ideal situations, your needle will maintain a posture right in the middle of your gauge.

What to do after replacing a thermostat?

After replacing the thermostat, refill antifreeze. Leave the radiator cap off, and start the vehicle. Wait five minutes to allow all of the antifreeze to circulate throughout the engine. Turn off the engine, and allow the engine to cool.

Will a car overheat if thermostat is removed?

If you remove the thermostat, your car will run cold in cold weather. In the summer. Your car will run between 190°F-200°F with or without a thermostat. Both will take longer to heat up to operating temperature.

Will an engine overheat without a thermostat?

Running an engine without the thermostat can cause the engine to overheat due to the coolant passes through the engine too fast and will not let the coolant absorb the heat from the engine.

Will removing thermostat stop overheating?

Removing your engine thermostat will not prevent overheating. In fact, removing your thermostat can make an overheating problem even worse. That’s because the thermostat creates a small restriction in the cooling system which allows the coolant to take on more heat.

Do modern cars have thermostats?

Any liquid-cooled car engine has a small device called the thermostat that sits between the engine and the radiator. The thermostat in most cars is about 2 inches (5 cm) in diameter. Its job is to block the flow of coolant to the radiator until the engine has warmed up.
