Urgent Codes p0117 and p01116

P0117 is "engine coolant temperature circuit low input.
There is no P01116 (too many digits), but there is a P0116, which is "Engine Coolant Temperature Circuit Range/Performance Problem"

This is assuming the code reader your tech used was actually reading codes correctly, because there is also a:

P1116 which is Coolant Temperature Sensor Circuit Stuck for Coolant Heat Storage System
P1117 which is Coolant Temperature Sensor Circuit Low for Coolant Heat Storage System

The P1116/P1117 combo, I would have no problem continuing to drive the car home.

The other combo P0116/P0117 you may need to get the temperature sensor replaced. I'm not 100% sure how that sensor would affect continued driving.

Just as a precaution, I would probably verify engine coolant level and reservoir level.

 

Drive on get to South Carolina wherever you're going you're not going to have any events seriously and this kind of weather we're having too yeah I would say go on to where you're going I'm driving the same kind of car with way more codes and way more problems and never have a problem with it at all I can pretty much promise you you're going home to South Carolina if you desire

 

Nice careful analysis. I was about to miss that there were two different ways to read the too-long code.

The P0116/P0117 would make perfect sense together, and might be pretty easy to fix. I'd say it's more likely to be the wiring to the ECT sensor than the sensor itself. Those sensors really don't have much way of going bad. And a wiring issue might be fixed with no more than a little bit of cleaning, taping, or splicing.

 

Sounds like there may be an air bubble or something your temp sensor may be sitting in air instead of red coolant or something along those lines and this weather that we're having the last few days the last week or so generally's been relatively cold until the last couple of days Prius generally won't have an overheat problem in that kind of weather I mean unless you've got a serious blockage like a closed thermostat so on and so forth which is pretty rare on these models actually but good you made it home should be pretty easy to get checked out and get straightened out this is a good model to keep running.

 

Dash cam screen You're talking about the little green car is turned red and it's got a line through it or an arrow or some such nonsense that sounds like your inverter pump is gone bad That's the little pump that's behind the left headlight You should hear it making noise when you open the car door and so on and so forth just a thought or maybe that car turns red for a high coolant temp but I think that's high coolant temp for the inverter not the radiator and the ice engine but I could be wrong.

 

What Tombukt2 is talking about here is the little red-car-! icon that can get drawn over the top left corner of whatever screen you are viewing:



so if the screen you happen to have up is the Energy Monitor one (which has a little green car in that corner) and this icon gets drawn over it, and you're not paying much attention, you might think it's a little-green-car-turns-red kind of deal.

If that icon appears, it means you should read trouble codes from the hybrid system; there are a couple hundred, so it is better to find out which code(s) you have than to try to guess.

 

Is the drive belt for the water pump ok? Coolant level in the radiator ok? (check when engine is cold)

Could be a thermostat problem or radiator fans. Most faults with the temperature sensor or wiring do not set this code. (usually I see open circuit - voltage high codes).

Overheating due to a bad head gasket is really rare on any (non Gen3 prius) Toyota.
