Code meaning?

google says fuel pump relay.

 

i can't link, but it's from the thread 'Car went to limp mode then stopped with P0A0F after maintenance'. by member 'EboMike' fro 10-19-13.

 

that's unusual in a 2012, how many miles?

 

Given the failure of the engine to run and the other issues you noted, I suggest that you have an engine compression test or leak down test performed to see if the engine has any serious mechanical issues like worn piston rings.

 

If you looked closely at the chart RRxing posted for you, you might be wondering, "hey, how do I get those extra three digits that help pinpoint the code meaning?" The answer is, that's called the INF code, and you can go back with your code reader and pull it.

In case you're wondering even more, "hey, that chart is kind of like fortune cookies, where could I find actual troubleshooting steps to start with the code I've got, test things, and find out what my problem is?" the answer is: your repair manual on techinfo.toyota.com.

But even from the fortune cookies we can see they almost all can involve the Sequential Fuel Injection system. Clearly your problem is too much fuel, not too little, so the googled thing earlier about the fuel pump relay was not only a fortune cookie but also wrong. My money would be on an injector (or more than one) that is not completely closing, so that fuel leaks from it. The engine floods, is hard to start, makes black sooty exhaust, and leaked fuel ends up in the crankcase oil.

That will also quickly trash the catalytic converter, so best to get it fixed promptly.

I have a spare set of Gen 1 / Gen 2 injectors, but I guess they're probably different for the Gen 3 1.8L.

Honestly first time I heard about this but it worth a try
