Hello,
My Civic was taking far longer than normal to warm up to operating temperature (often it did not even warm up completely before arriving to my destination). After a week or two the CEL came on and gave a P0128 code. I replaced the thermostat with a non-OEM one from Autozone and the problem went away.
A few months later the P0128 code came back. The time it took for the engine to warm up was normal and it consistently ran at operating temperatures. I did some research and found out that it would have been better to use an OEM thermostat. So, I installed an OEM thermostat a month ago and cleared the P0128 code with my OBDII sensor/reader device.
About a week ago the P0128 code came back on. Also, the operating temperature seems to be slightly lower than it used to be (before I ever got any P0128 codes and changed the first thermostat). The car does warm up in a reasonable amount of time and once it is warmed up, the temperature gauge stays steady.
I am confident that my coolant level has always been full and that there have been no bubbles in the system.
Do you have any ideas of what I should try next? Thank you for your time.
-Jeff
