2007 Prius P1116 code and coolant control valve issues

[captainspecs]

I have a 2005 Prius and have the same Coolant Control Valve issue. The Chk Engine light came on steady for a while and now is intermittant. I took it to the dealer and the problem code came up as P1121 Coolant Control Valve Malfunction. The technician said there was a Toyota Corp. Advisory on this problem and he verified the malfunctions using the specifications in the Avvisory. I was given an estimate of $933 to replace the valve and flush the system. That cost seems to be excessive. When I suggested that the dealer just flush the coolant system they said that would cost $360 alone, so it would be more cost effective to get the valve replaced and the system flushed.

It seems there should be a less costly alternative. The Prius , to date, has been a fine auto, but at only 30,000 miles, a thousand dollar expense is disappointing to say the least.

Previous postings of costs looked to be half of that. I'll probably call around to other Toyota Dealers in the area to get other estimates

TSB EG001-08 is applicable to your situation. Unfortunately the valve is covered under the 3 year/36K mile warranty. Your car is only 4 years old and logged 30K miles. If you call the Toyota Customer Experience Center and ask for financial help from Toyota on the repair, you might be pleasantly surprised.

Also, note that the valve, 16670-21010 has an MSRP of $66. A couple gallons of SLLC will cost around $50. It is probably a two hour job, so a price of $933 does seem unusually excessive.

The service dept will probably make more profit on this service visit than the new car sales department will make selling a 2009 Prius...
