P0128 CEL, Temp seems Normal




Is this a sensor issue?
For my case, I couldn't clear the error from memory, as it's pending I suppose. The light will go away but the error couldn't be cleared with my code reader. The light will come back after awhile.
Engine temps looked normal to me too. But I guess it was because the engine took longer than usual to get up to normal temps. Not sure what the specified time is, but that was the problem. I replaced the thermostat and I didn't notice a difference in engine temp, but the code went away completely lol maybe it was off a few degrees but unnoticeable from the gauge.




I presume that there's no danger putting this off?

If your have emissions test coming up it will auto fail too with a CEL.





As for fuel economy, it's difficult to tell since I've been running the A/C

But to your point, yeah, I know I'm on borrowed time.
Thanks
