Is the engine coolant temper
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.

If the above items check out good, replace the thermostat If Nissan vehicle, check for Technical Service Bulletins (TSBs), as the ECM may need to be reprogrammed to correct the P0128 code Other ECT sensor and circuit related DTCs: P0115, P0116, P0117, P0118, P0119, P0125 Register now to ask a question (free) Related P0128 DTC Discussions2005 Honda civic 1.7 losing coolant p0125 p0128 p0662Car losing coolant, none in oil.

Category:Ford Share this conversation Expert: Mike S. replied4 years ago. P0128 refers to the Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature). What this indicates is that the thermostat monitor has not achieved the required engine operating temperature within a specified amount of time after starting the engine.Possible causes are:Insufficient warm up time Low engine coolant level Leaking or stuck open thermostat Inoperative engine coolant temperature (ECT) sensor Inoperative Cylinder Head Temperature (CHT) sensorI would first of all check the fuses, remove the radiator cap while cold, make sure the level is full, then start the engine up. If you have a kitchen thermometer, place it in the radiator, perhaps with some mechanics wire wrapped around it so it don't fall in, and watch the temp as the thermostat opens. If you see coolant flow out the tubes in the radiator when cold the thermostat is already stuck open.Let me know at what temp the thermostat opens. Ask Your Own Ford Question Expert: Mike S. replied4 years ago. Do you have a degas bottle with the cap there or is the cap on the radiator? Also, do you have an electric engine cooling fan or a mechanical or both?Are the fans or fan coming on when the engine gets hot or running all the time?I have a test procedure here for that code P0128.
