Check hybrid system warning after manifold cleaning

That’s what I have (bit from a different seller).

As long as you have the laptop, you’ll be ok. More than likely, you’ll need to troubleshoot the connection once you have the software loaded.

Good luck .

 

The P3190 has a “snowflake” that will give you additional information .

Did you click on that to see what would display?

I’d also look at the fuel delivery as this code could point to the fuel pump.

Glad to see Techstream is up and running .

 

Not sure how relevant this is, but just FWIW:

2-3 years ago on our Gen-2, I had the dealer do a throttle-body cleaning. After that, the check-engine light came on and the engine ran at fairly-high RPM pretty much continuously for the next hour or so. After that it was all fine.

Actually, thinking back, I think it was an injector/intake manifold cleaning. Sorry, it was a while back...

For sure invest in a dealership diagnosis, shouldn't be over $100. Plus tow.

 

Help refresh us on the troubleshooting you have done, mainly:

• Have you cleaned the MAF sensor?
• Have you changed the spark plugs?
• Have you swapped coils?
• Cleaned the throttle body?
• How much gas is in your Prius?

You have Techstream and don’t have a hybrid battery code showing.

I’d focus on what Techstream said and avoid starting the car as much as possible as the hybrid battery will continue to drain each time it is started .

Good luck and keep us posted .

 

Did you use new gaskets when you put your car back together?

I'm thinking a misfire because of a vacuum leak, intake manifold.

MAF engines do not handle any type of external air leaks. Any air getting to the engine that does not go through the MAF can create a lean condition causing a misfire. Using my own logic it should be on multiple cylinders.

 

Since P0A80 has displayed:

• Are there any other codes on the Hybrid ECU menu?
• What is the readings on the live data for each block voltage?
• Each block voltage internal resistance?
• How much voltage is the entire pack reading?

You also said that when you cleared the codes that the ones in the picture are what returned? If so, there is a fuel delivery issue or something where the air tonfuel ratio is out of whack or different than what the computers expect.

 

^ Smoking gun is that it runs for a few seconds, and then shuts down?

 

I just did this to my gf's 2010 Prius yesterday: new PCV (horrible location design), EGR, intake manifold, throttle body, MAF, brake fluid flush. I had to pull a lot of cable wires. Almost similar symptoms you had experienced came on. Codes from my techstream:
- P0A0F (Engine Failed To Start),
- C2300 Actuator System Malfunction,
- P0328 Knock Sensor 1 Circuit High Input,
- P261c Coolant Pump 'B' Control Circuit Low.
I retraced my steps and found 3 unplugged electrical wires off of one harness, that was located under the air intake tube/airbox. I am usually very thorough, there were no other extra parts when i concluded that project early AM. A lingering CEL stayed on my dash as I road tested it around the neighborhood at 40mph. I assumed the light would stop later. Hours later I drove the car on the highway (70mph) for 5 miles; stopped for dinner; then took off to an autoparts store up the road when Prius started to light up (yellow triangle, traction, brakes, NOT RTD), lose throttle and coast to deadstop. The battery was only draining down from full bars to 2bars; it never regenerated. At stop, we did have access to the rear trunk for tools.

1- NEED AN OBD2 code reader to diagnose issues. Unfortunately many symptoms are shared with many diff problem codes. Symptoms can indicate many things. If you are trying to do your own work or even care to arm yourself with a baseline info before approaching a mechanic-- get an OBD2. Your needs have grown since you purchased the Prius years back.

2- TRIPLE CHECK the reassembly work for electrical connectivity and ensure no extra parts remain and all things coupled and not dangling.

I have learned to now have 2 cars to tinker with; when originally tinkering with my one daily driver overly stressed me
patience & good luck!

 

Psshhh, I put on a new PCV valve and oil catch can every oil change and my car runs great!

 

Is the hose to the PCV valve on properly?

 

Seriously??
