Do the vehicle start? But run poorly?
Ask Your Own Toyota Question
Customer reply replied 3 months ago
It starts and runs smooth and quietly.
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
I believe the noise you heard is a hose being disconnected by a malfunctioning valve. Check around your throttle body and air filter box for a disconnected hose.
Ask Your Own Toyota Question
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
This sounds familiar
Ask Your Own Toyota Question
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
You may have to remove the airbox to inspect. The hose should be attached next to the throttle body
Ask Your Own Toyota Question
Customer reply replied 3 months ago
The car started after we cleared codes and drove less then a quarter mile turned off , now it says P lock malfunction when parking again and won’t start
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
Yeah, clear all the codes and do the key cycle again. Don't drive it, the problem haven't been fixed yet.
Ask Your Own Toyota Question
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
Just clear codes and key cycle then repeat till back home.

U0293 is the new code for lost communication with hybrid control module
Customer reply replied 3 months ago
Ok I will clear again
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
The p0102 indicates an incorrect mass air flow reading.
Ask Your Own Toyota Question
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
Disregard the communication codes, the engine died so that's normal.
Ask Your Own Toyota Question
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
The problem should be a disconnected vacuum hose to the throttle body. I remember a service bulletin that pertains to this.
Ask Your Own Toyota Question
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
Where the air filter is, it's connected to the throttle body. If you look in that area you may See it disconnected.
Ask Your Own Toyota Question
Customer reply replied 3 months ago
All air hoses are connected
Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago
Even the small ones under the air box? You may have to remove the air box. To see it.

Toyota Mechanic: Daniel Lee, ASE Certified Technician replied 3 months ago

Using a small Phillips screw driver apply good pressure to remove or it'll strip out.

We need to take it out to check the other elements. There's another set I believe.
