hello, thanks for being on the web! i have been needing information on this! 4 months ago i had a code to replace the coolent temp valve. no problem, dealer did it. one month ago code came on for the coolent temp sensor, they had informed me that would be best if i had the heat tank and three way valve also replaced-all this for about 2500$! i said no thanks and just the sensor replaced. two weeks after had the same code on again. took it back to dealer and reqeisted for them to check the temp sensor make sure it works and clear my code. they are covering them selfs with, " now the probable cause is the heat tank and three way valve." my question is, why is the tank not sending its own code? the code now is p1116 the same for the sensor i replaced a month ago. they said that the only way theyll give me a guaranty is if i have the heat tank and three way valve replaced...for 2400!
the tech mentioned that the tank could have debris in it and blocking water flow.
would i damage my engine if i drive it like this? 2009 prius, 205000mil. -
It's difficult to say if you can keep driving your vehicle with the code.
It looks like your dealer is not performing any testing to diagnose the problem, just trowing in some parts.
Unfortunately I never had that problem before, but based on a national database of repairs for your model year and the P1116 code, the most likely cause of the problem, besides the coolant temp sensor, is the "Coolant Flow Valve"
