That code means that the coolant is cooler than it is supposed to be and it cannot be regulated...which means the thermostat is stuck open or broken,so replace the thermostat and that should solve your problem,hope this sheds a little light on it!

I loss power while driving then check engine light turned on. what will i do?


You need to go to an Auto Zone or other parts store and have them hook up a code reader to see what codes are stored. That most likely will give you a good idea why you lose power and for sure why the Check Engine light is on.

Then if you still need assistance, get back here with the codes and I can try to help you further. Just cannot do anything without the codes since your Check Engine light is on.

O6 ascender po128 code changed thermostat and coolant sensor. ligt comes back on with the same code after three months. any suggestions


Code P0128 simply means that the computer has not seen a large enough rise in engine temperature within a prescribed amount of time. This can be caused by several things. It could be a bad (stuck open) thermostat, the wrong thermostat (not the correct heat range for the vehicle), a bad coolant temp sensor, bad wiring between the coolant temp sensor and the engine computer, low coolant level or airpockets in the cooling system, or a failed PCM, or a PCM that needs to be reprogrammed. It could even be caused by a cooling fan relay sticking on. You could throw a lot of parts at this code and not fix the problem if it is not properly diagnosed. You have to access the computer data to find out what temperature your computer "thinks" your engine is at. You must then compare this with a direct reading from an infrared thermometer or a pyrometer to validate this data. If the data is not valid, then you must find out why. (bad sensor/sensor circuits, etc.) If the data is valid, then you have to find out why your engine is running cold.
