P3190, shudder, doesn't run after EGR and IM cleaning

I'll start by saying I'm new, and it's not a prius but a 2012 CT200h.

Car was running fine, but would throw a P0420 and P0401 every other day. With the CEL illuminated, the car drove as if it didn't have any issues.

To remove the constant CEL, I decided to clean the EGR valve, cooler, intake manifold and throttle body.

After putting it back together, it had a bad shudder/shake at start up, and ran for about 15 secs for sputtering a turning off. A restart yielded the same results but it started to get mad throwing every warning light. It was showing P0401, P0420, P0453 and P3190.

Looking for insight as the car can't move and only runs for about 10 secs.

Thanks!

PS I've ordered a new intake manifold gasket and will go over that area with a fine tooth comb as it feels like its vacuum leak related.

 

I forgot to put the miles, 155k.

I thought I got all the lines, but I’ll be double checking when I do the intake manifold. I do recall a loud hissing noise when it was trying to run.

It’s rather annoying car to troubleshoot given I have a limited number of restarts. I just rebalanced the pack so I’d rather not do that again.

 

Another thing, I did pull off the top of the EGR valve to inspect the magnet, and didn’t realize it “spins” so not sure if there is the certain way to clock the valve and if that would cause any issues.

 

Well it's running, and a quick test drive seemed normal. It seems I left off PCV vent hose. Still need to clear codes and such to see if my EGR cleaning has solved my P0401 and P0420 code, but I was able to drive around the block, drprius app stating 60% SOC on the hybrid pack so feeling better about that as well.

 

I looked, but wasn't checking for the rut, mainly any corrosion on the coil. I do recall seeing some for of notch in the ramp. We will see if the code comes back, might get a new EGR to rule out any issues I caused by pulling the solenoid.

 

Drove it for a bit longer, runs better, but still throwing the P0401 and P420. Wonder if it needs a new CAT or downstream o2.

 

Yea but it sets them at the same time, any experience if one influences the other? It also has a P0453 and a gas leak if you fill it up. So things are going well...
