I have 2010 prius it was making noise like real raling and codes on dash was p0352 p0403 p0302 p0304 p0420 i put new cooler assembly cleaned EGR valve both pipes intake very very well replace new coil all 4 replaced plugs all 4 and no luck same ratling same code 302 and 304 disconnected EGR but same from 4 months check hybrid battery rectangular sign was comming and it was running good the battery sign shows full up till half and gos back full i was keep driving and one fine day it start this ratling and lights on das it has 254k miles
I lose engine coolant on mine I believe same issue. I’m swapping those parts out in mine. Intake manifold had oil, I bought a new intake manifold, EGR assembly, EGR pipe and PVC valve. Hopefully this fixes the issue 😊
@@CesarMartinez-zb1zb Way to go! As you know that when Egr unit clogged up with waste of exhaust gases, pistons start to suck up air that was supposed to come from EGR does not come and that eventually brings about pulling oil from PCV valve into the intake manifold especially to where throttle body. I hope that this makes sense. This is how I figured out the root cause analysis 🧐. Thank you so much for responding!
@@jamalnasir2846 Have you checked a sensor that placed in air filter assembly & housing? I forgot to connect Mass Air Sensor after doing basic maintenance. It triggered “Check Hybrid Battery” warning on the dash and lead to engine shot off pretty frequently.
Good tip, Thanks
You did not show how to test the multi meter at all!!😢

Hi @jamalnasir2846, thank you for dropping off your comment here.
Have you also noticed that you are loosing engine coolant time to time?
@@WIP0 no i am not loosing coolant
