2007 Prius P1116 code and coolant control valve issues

[mpbrisson]

Re: Mike Dimmick...The first visit was code P0125 INST TEMP FOR COOLANT CLOSED LOOP. The correction listed by tech: Reprogrammed PCM EG8014. No part replacement.The second visit produced code P1121/SERVICE BULLETIN #EG001-08. Correction listed: R&R Coolant Flow Control Valve, part 16670-21010 Valve Assy, Water W replaced.The 3rd visit produced code P1116 TEMP STACK MALFUNCTION DUE TO FAILURE INTERNAL OIL TEMP SENSOR. The correction listed: R&R Coolant Tank Temp Sensor, part 89429-47010 Sensor, Temperature replaced.The 4th visit produced code P1116 3 times since replacement of CHS Valve. Local tech spoke with corp. tech, who told him to bleed and retest. If that did not work, replace valve again, which the local tech did.I continue to get P1116. That's why I've been looking for answers in this forum and currently have Toyota looking at my case. The above info was pulled from dealership tickets... Thanks

This is a nightmare epidemic. 3/4 same or similar cases? Is this what I have to look forward to?

Toyota Corp. has set up an appt. for a regional tech rep to look at my car Tues the 27th. I will let you all know the outcome.

ok, so it took them 4 days to figure it out. I called that number that number in my last post. This number is Toyota's Corp line, i told them the whole story, and they had a team look into my issue. A Master tech from Toyota went out to look at my car. Apparently they put the piece in incorrectly, the hoses were in the wrong places. They had to compare my prius with another 05.

The person that i talked to said they will give me a refund of the original part and labor because of the mishaps, aside from my being a loyal Toyota customer. REFUND!!!

I guess the problem is finally fixed after having to contact the higher authority. After using that loaner car(rav4) i missed my navi, auto key sensor for unlocking and ignition, and most of all gas saving features... blah...



Call Toyota Corp at 800-331-4331 and complain about the issue, maybe if you bitch enough, they will even get you a refund.. lol

that coolant sensor is only covered under a 36k/ 3 year warranty, but i think that is BS. I complained that due to this being a direct part of the hybrid system this should be a 60k, 5 year part. I even referred them to the TSB that this is a known problem part.

Just to update everyone, I should have my prius back this week sometime. I've had the loaner now a full week. The Master Tech looked at my prius last Thursday, and they've ordered parts etc....something about replacing the 'coolant tank assembly' and other parts associated with that.

I will post the exact parts and problems addressed after I pick up the vehicle. It's tough to remember the exact details of the conversation.

The *next* time you need service for whatever, is there another Toyota dealer available to you?

[mpbrisson]

My current dealer is 90 minutes away...the next closest dealer is 2 hours 15 minutes. I know what you're hinting towards. I'm picking up my car this evening. We'll see how it goes, and if I have another issue (fingers crossed), I'll just have to consider all my options....again.

4:45pm: Picked up my prius. They replaced 3 parts. 87200-47030 Accessory Assembly, 16660-21011 Tank Assembly, 89422-33030 Sensor Water Temp. Total cost under warranty for parts and labor $2340.08

5:00pm: Leave Toyota Dealership.

5:15pm: 30 degrees outside, and I notice the car is not heating up. Heat is not working at 72 degrees, so I crank it to 76...still not warming up. Next thing I know the Red Exclamation Point lights up the dash. I pull over, call the dealership, and decide to bring it back. On the way back I get the Red Exclamation Point, then the Navigation screen says "Problem", and flashes a small red thermostat.

6:00pm: I'm own my way home again with the loaner I just spent a week and a half in.

I'll be dealing with Toyota Corp. in the morning as my case continues to get more interesting. I'm at my wits end. I have no idea what to do. I have not driven my car for any meaningful amount of time in 3 months. I continue to make payments on a car I haven't seen and cannot drive. I no longer have confidence in this vehicle...I don't know what the next step is.
