Gen II dead -- please help me diagnose the issue

As I said earlier removing the 12 volts blows out all stored error codes which sometimes come in handy if the repair is mis-diagnosed and you need to get on track to what the real issue is. Also blows out the radio presets and the auto window settings. Both very easy to set.

Remove and replace the throttle body should take 2. hours. Fairly easy. 4 nuts 2 hose clamps, and 2 electrical connectors. That includes a good cleaning of the used one before installation. Being able to clean the used throttle body out of the car is quite handy. Please take advantage of it.
If not you may be right back where you started.

Independent mechanic I use charges $80 an hour so that job is $195 with supplies and tax.

 

where are you located?

 

Well Jojo, what I would do then is tell the shop you want the old one, clean it up and get it operational and sell it on Ebay to offset the cost of the used one. lol

 

I think your mechanic is on the right track. I just had the throttle body go out on my 2005 with 117k miles. Mechanic tried cleaning it but it would not work and needed replaced. I was throwing codes P2111 and P2103, both relating to throttle body. Car would start and run but when given gas would not rev. After idling like that for a while it threw a code P0A80 indicating a problem with the HV battery.

We picked up a used throttle body from a junkyard for $200 with a 1 year warranty and swapped them out. Performed a force charge by making the Prius READY, shifting to D, then holding the car stationary by applying the brake pedal with your left foot while flooring the accelerator pedal. It's run fine ever since. No HV battery problem or any codes. The throttle body swap took about 10 minutes.

 

Excellent post.

Thanks to your post I now see why Jo Jo still is throwing the P3000 because the Hybrid Battery is very low and the system is not happy with an idle charge at that low of a charge. Software is commanding the engine to fast idle to charge the battery and it refuses so it throws that battery code. I suggest the op do the same as you did.

dpeverhart-Do you know what failed on your tb? Was the throat corroded or the motor failed?

 

Hi JoJo. When the throttle body is fixed and the Prius first started, it will automatically run the engine at a fast idle for several minutes to recharge the HV battery (with the transmission in "P"). It will then cut out when it reaches 2 or 3 bars. As Ed said, it's probably been trying to do this, but unable to due to the dead throttle body, and hence the P3000 code.

In addition to just leaving it "P" and letting the Prius automatically bring it back to a safe (but still fairly low) level of charge, you *can* do what's called a force charge. To force charge you place the transmission in "D", and with your left foot *firmly* on the brake, you apply moderate accelerator pedal until the engine revs enough to show green charging arrows into the battery. Using this forced method you can bring the battery all the way up to 7+ green bars if you want to.

To be honest though, I personally recommend merely placing it in "P" and letting the Prius automatically bringing up to 2 or 3 bars at fast idle. When it finishes this and the engine shuts off, then just take it for a drive and it allow it to recharge the battery to 5 or 6 bars as per usual.
