Prius Starts Stutters then Stops

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.

Prius 1 - Malfunction in LInear Solenoid

Fault codes as follows 
Engine - none

hybrid ECU -
2678 : battery system failure
2679: HV battery failure
2681: ILK disconnection 2 (interlock actuated)
2762:

battery -
2544: general battery fault

ABS -
0278: open circuit in ABS solenoid relay circuit
1216:  high positive voltage of linear solenoid
1241: low or abnormally high battery positive voltage in IG1 circuit

Possible Solenoid failure - High voltage triggered the Triangle error.
No faulty cells found.
All fault codes cleared. Car running as normal.
