Throttle Motor Issue On A Toyota Hybrid

[B2Spirit]

Out of the blue i got the "Check Hybrid System" message along with the check engine light and master warning light.

There was no prior warning and the errors are not going away.

it's throwing P2111 and POAOF error codes.

How it happens is like this.

1. Start the car. Above warnings come up.

2. Engine Starts, Responds to throttle and car runs without any discernible issue.

3. When the battery charge is sufficient it switches to the EV mode and the master warning light starts blinking along with a beep.

4. After that when the battery drops to below sufficient levels or when i press on the accelerator(even if i press it all the way), the engine does not kickback to life.

5. So I turn off the car.

6. When i turn it back on the, engine kicks in to life and the same cycle happens (2-5)

The car has 38,000 Km on ODO. It's a personally selected car from auction/Dealer, so i think ODO tampering is not an issue (The car was checked out when it was brought to SL and it had 9300 KM on the clock at that time).

I have turned over the car to the agents and they are still checking whether there is anything that can be done without replacing the throttle body w/motor unit.

Any suggestions would be helpful.

What happens if you drive on power mode?

No Power mode on this model, I believe the power mode is only available in Prius.

Eco & EV are the only modes available

P2111 I believe is a standard error code for the throttle body or some actuator in it getting stuck. Curiosity got the better of me and looked for the POAOF error and found out that this guy did a DIY cleaning job with his TB

Here are some interesting articles I found...

Well the verdict has arrived that the throttle motor is busted. So the recommended solution is to replace the entire assembly as it comes as a sealed unit.

Is it possible or worth trying to repair this unit considering its criticality ?

Check the prices of used and new units before considering a repair.

does it have any electronic components in it? The time will come when these are repaired in SL but it might be too early. You can try letting a smart chap have a go at it, but best have access to a replacement in case it does not work.

personally I'll go for a replacement unit, and then experiment with the broken unit, just for curiosity.
