Prius Generation 2. -
1) A common problem we see in this model is the throttle body sticking. Leads to poor performance and poor fuel consumption. Freeing up the spring mechanism fixed the problem.
2) Vehicle starts up stutters then stops. The cause could be carbon built up in the exhaust. Blowing the exhaust system out may fix the problem. Another cause could be excess oil in the throttle body. Can be seen if you remove the air filter. Pour some petrol down to dissolve the oil and start the vehicle. This may solve the problem. Oil deposit was caused by excess oil in the engine from overfilling.
All the above problem will affect the battery causing it to fail. Proper servicing from knowledgeable technicians about hybrid vehicles will save money in the long run.

Prius Generation 1 High Voltage Leak and Power Jockey
Error Codes
C2577 - High voltage system insulation failure
C2668 - High voltage system leak
C2577 is an error code related to the battery. This was fixed and cleared.
C2688 is an error code related to the hybrid system. We were unable to clear this as it would involve checking the whole hybrid drive train.
The problem with this vehicle is that no matter how good a battery we put in the vehicle, the turtle will appear and the battery soon drains out.
One final solution is to install the power jockey hoping that it will at least allow the vehicle to operate normally. If this does not work then the leak in the hybrid system must be fixed.
This particular vehicle was reconditioned and repaired 4 times with the whole battery pack changed twice. Never ran for more than 2 days before battery pack collapse. Running with the power jockey engaged over 80 KM, turtle appeared under hard acceleration Triangle error cleared itself near the end of the 80 KM run. Quite likely the problem in the hybrid system still exist and will recur. However the power jockey seem to bring the system back within it's limit of tolerance.
Quite clear that without the power jockey this vehicle is only fit as scrap metal.

Can I Gurantee That The Power Jockey Works?
I have been asked this question by hybrid vehicle owners wanting to have their batteries reconditioned and having the Power Jockey fitted.
Can I guarantee that it will work?
This is a great question and I think you should look at it both ways.
The Main battery is getting old. It was calculated to last 7 years
That in itself is a feat as the same batteries (NIMH cells ) used
in drills last between 6 months to 1 year if used every day. Obviously it is the
way that the battery is used that gives it the long life span.
With reconditioning we try to extend this "life span" This is done
by bringing the battery to within accepted levels as detected by the
vehicles systems. Though some have gone 3 years after reconditioning
most have failed again within 2 years, Batteries after reconditioning
are still fragile and cannot take on too much stress.
When these batteries are approaching 12 years old reconditioning does not
seem to be enough to keep them within the acceptable limits of the vehicle
operating systems. This is why we developed the Power Jockey as a
battery augmentation system. So far as we know, from the installations
since the beginning of November, there have been no failures in the 20
installations and counting. Results are encouraging. In fact they are beyond
my expectations.
We have not stopped there. By January we will introduce the Power Saddle
(now under test) which fits on the power Jockey and really puts a "tiger in
the tank" These two developments stretches the "life span " envelop of
HEV batteries, hopefully (fingers crossed) for the remaining life of the vehicle.
Now, can I guarantee? Well I don't have enough information to guarantee.
It's like having an untested cure for a terminal condition. Without it you
haven't got a vehicle. Do you want to be one of the first to try?
The only guarantee I can give you at this stage is a year warranty on your
battery after you install the Power Jockey.
I have tried the system and It makes the car incredibly powerful. How it can work is still a mystery to me as, if it was that good, why haven't Toyota or others smarter than I, discovered it? Ehmm - Perhaps they haven't looked here yet!!
