How do I fix code P0128?

How do I fix code P0128?

What repairs can fix the P0128 code?

1. Replacing the thermostat (most common repair)
2. Replacing the coolant temperature sensor, or the wiring and connector associated with the sensor being damaged.

Is it OK to drive with P0128?

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.

What causes a P0128 code?

If your coolant condition is poor, flush the coolant system and replace the coolant. If the coolant level is low, fill the coolant system and check for leaks. The coolant temperature sensor can be checked with a multimeter. The most common cause for P0128 is the engine coolant thermostat is stuck open.

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.

How much does it cost to fix P0128?

For example, if the faulty component triggering a P0128 code is related to a bad coolant temperature sensor, repair costs ranged from $140.00 to $190. Although hand, if the problem is coming from a bad thermostat and requires replacements, expect to pay somewhere between $220 and $250.

What is the ECT sensor?

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.

How much does it cost to replace a coolant temperature sensor?

The average price for an engine temperature sensor replacement is between $150 and $193. Labor costs are between $82 and $105 while parts are between $66 and $88.

How do I fix code P0137?

What repairs can fix the P0137 code?

1. Replacing the O2 sensor for bank 1 sensor 2.
2. Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
3. Repairing exhaust leaks before the sensor.

What does the cylinder head temperature sensor do?

Thermometrics Cylinder Head Temperature Sensor is designed to take the place of one of the cylinder head bolts on a diesel engine. The sensor’s purpose is to measure the cylinder head temperature and to signal the vehicle’s operator if an engine overheats (that is, if an engine over-temperature is taking place).

How do you know if you have a bad ECT sensor?

If you notice more fluctuation in your engine temperature or it looks higher or lower than usual while you’re driving, it could be the engine coolant temperature sensor. In particular, if your engine doesn’t seem to be warming up as it typically does, you should have a mechanic take a look at your cooling system.

What does p0128 stand for in engine code?

Code P0128 stands for Engine Coolant Temperature Below Thermostat Regulating Temperature. It means that the ECM/PCM has “noticed” that the engine coolant temperature is consistently running below thermostat regulating temperature.

Why does my car have trouble code p0125?

For most vehicles, trouble code P0125 is related to this issue as well. Your thermostat is an essential component for regulating coolant temperature and checking for more serious issues with your engine. However, a damaged thermostat won’t typically cause any performance issues.

What causes code p0128 on a Chevy Trailblazer?

Common problems causing the code P0128 in different cars: In many GM cars and trucks (Chevrolet Trailblazer, Silverado, HHR and other models) the code P0128 is often caused by a sticking thermostat. In some GM cars when the code P0128 is set, the temperature gauge stops working and the radiator fans run constantly.

What does Powertrain Control Module ( PCM ) do?

The powertrain control module (PCM) tracks how long it takes for the engine of your Chevrolet to reach and maintain the correct operating temperature.
