P0128


Hi Kelly:
This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125

A code P0128 may mean that one or more of the following has happened:
Low engine coolant level
Leaking or stuck open thermostat
Faulty cooling fan (running too much)
Faulty coolant temperature (ECT) sensor
Faulty intake air temperature (IAT) sensor

Sometimes Autozone or Autoshop with scanner reader tools make this for free. Feel free to contact us in the previous code links.

Also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

What's your problem?error code 0128


DTC P0128 - Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)
This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125

In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant temperature (ECT) sensor reading, and the speed of the vehicle. If have other request, just contact us about OBD Diagnostic Truble Codes.

Hope this helps.

Check engine light on 2004 GMC Envoy. Had air intake sensor replaced. Failed inspection diagnostic code came up P0128. I have been told I needed an air pump, a tune -up, injectors cleaned etc. etc., I have...


Code P0128 indicates a faulty thermostat, more than likely it is always in the open position causing the coolant to come up to operating temperature too slowly.
My suggestion is to find a different repair shop.
