Toyota Prius P0A0F And P3190 No Throttle Response: SOLVED

There are few things worse than getting a trouble code on your Prius when you least expect it. Is it a failed hybrid battery? A water pump? Head gasket? The swarm of thoughts can quickly strike fear into your heart.

Rest assured you are driving one of the best-designed vehicles, a Prius. More than likely, your problem is not as bad as it seems. In my recent event with these exact trouble codes, I learned not to panic but be analytical with the issue.

What Causes A P0A0F And P3190?
Both of these codes first need to be broken down. If you do not understand the description of the code, you will never find the root cause for it.

A P0A0F is defined as Engine Failed To Start. A P3190 is defined as Poor Engine Power. While these codes seem vague, they are pretty helpful in the diagnostic process.

The possible trouble areas for a P3190 are:

Air induction system malfunction.
Defective throttle body.
Improper fuel pressure.
Defective engine.
Defective Mass Airflow (MAF) meter.
Vehicle is out of fuel.
Defective Engine Coolant Temperature (ECT) sensor.
Defective crankshaft position sensor.
Defective camshaft position sensor.
Defective Engine Control Module (ECM).

The possible trouble areas for a P0A0F are:

SFI system
Faulty Power management control ECU

So what causes these two codes could be anything on this list, and that is where skill comes into play.

How To Diagnose These Two Trouble Codes
These codes can be as easy or as hard as you make it. The first thing you need to do is consider what it is you are dealing with. Prius is a well-built machine, so things like an engine ECU or bad sensors will not be on the top of the priority list.

Sensors should be checked and verified, but only after you do the stuff that easier to access. Looking at the list, I know instantly I will check the fuel level and the mass airflow sensor. Why? Because of how easy they are to do. Add fuel (at least 3 gallons if low), and checking the MAF takes less than 5 minutes.
