2012 Prius V hybrid system warning and ignition error codes

So you say it is or isn't working properly?
Hard to believe that plugs would cause a hybrid light.

 

It's always unfortunate to get a thread like this where the actual codes from the car haven't been posted, as they would make the situation clear.

But it is not at all surprising to get the master warning light in consequence of an engine problem. The power management control ECU relies on the engine to be able to supply power to the hybrid system. It can definitely set a code like P0A0F if the engine isn't holding up its end of the bargain, and that will definitely give you the MWL.

 

There might even be folks here who could help with the research, if we didn't need Carnac the Magnificent to find out what codes you've got.

 

A bit of a dated reference, but good for a laugh:



Maybe we need to pay him more for better results.

 

The snowflakes you see in the middle of the screen contain more information on the issues .

Remember that for next time.

Glad you are back on the road.

 

Having all four of P035{1,2,3,4} certainly can mean that all four of your igniters have gone bad at the same time, though it can also mean (as the IGF circuit is shared by all four) that there is simply some wiring issue affecting that circuit, or affecting the supply common to the coils.

If changing all four coils has made the problems go away, I guess that was a good call this time. If it seems to return at any point, especially if it returns again with all four codes, it might be worthwhile to explore the possible causes outside of the coils themselves.

 

How could all four go bad at the same time...?

 

What did that cost?

I have replaced the
Water Pump
Traction Battery
Head Gasket
Break Pump and Master Cylinder
Invertor

 

That was low cost....... I thought it might be in the several hundreds.
Wonder what that would have been if it was original.
Thanks for the info!

 

Probably a hair under $340 for parts from a dealer, at discount. So a person planning to use dealer parts would probably put more effort into running down the other possible causes first. $62 replacement sets kind of change the approach!

 

I always wonder about the quality of those very low cost parts.
Few years ago I bought some fuel injectors for my Mercury Villager on Amazon and 2 went bad in a week. Replace all of them with ones from Orileys and never had a problem.
