My CEL came on last night the code that came up was P0116 - coolant temp sensor.
I replaced the T-stat about 3-4 months ago, flushed the radiator this summer with Toyota red and checked the PHH (which looks good). The heat works really well and the temp guage has never gone past the halfway mark (which I understand may be misleading).
I brought my LC to a local Toyota shop where they reset the code to get rid of the CEL. My question is that if this code pops up again my only option would be to replace the ECM. Has anyone changed the ECM or knows what this might cost?
