Question about 2008 Toyota Prius

2 Answers

2008 toyota prius: gas engine will not crank after removing and reinstalling the transaxle. auxillary battery is fully charged. i am rebuilding the vehicle. the engine ran prior to removing the transaxle. when the transaxle was reinstalled there initially was a problem with the wiring harness connector to the shift control actuator and the transmission would not shift ("Transmission P Lock Mechanism Abnormal was displayed on the multimeter display). After correcting the connection to the shift control acuator this message cleared and the transmission now shifts but the engine still will not crank when pressing the power button while holding foot on the brake and gas pedals with the parking brake applied. Could a DTC have been activated which is now preventing the engine from cranking? I did disassemble the transaxle case to have a crack welded but did not remove any internal components(the motor generator 1 which starts the engine is on the engine side of the transaxle case which is where I disassembled the case. Also could there now be a problem with one of the sensors (motor revolution sensor, ect.) which could prevent the engine from cranking?

    THE TRANSAXLE CASE WAS REMOVED FOR THE WELDING THEREFORE THE WELDING COULD NOT HAVE DAMAGED ANY ELECTRONIC COMPONENT. ALSO, THE PREVIOUS EXPERT SHOULD HAVE KNOWN WHETHER OR NOT THE PROBLEM DESCRIBED COULD HAVE LOCKED THE "IMMOBILIZER" RATHER THAN REFERRING METO A TOYOTA DEALERSHIP WHICH I WAS TRYING TO AVOID WITH ASSISTANCE FROM FIXYA. IF THE "IMMOBILIZER" IS THE PROBLEM HOW DO I CLEAR THE ASSOCIATED DTC, ECT?

Hi! Well since it's electrical related, I strongly suggest that you look on the ignition coil or check for a loose wire on the starter. This can be it why it doesn't start. Thanks

Check the Toyota dealer to see how the immobilizer works on the 2008 Toyota Prius and if the Transmission P Lock Mechanism Abnormal would trip it even after it was corrected.

I know that when welding parts, that the electronic parts can sometimes be damaged if not disconnected before welding.

This is the first time I have heard of the transaxle case needing to be welded due to a crack.

Good luck on this repair.

    I agree, that if the transaxle case was removed prior to welding that the electronics wouldn't be damaged.

    I believe that on a car as late model as yours, the DTC can be cleared, but the Snap On or Sears (available) scanner used must be updated to support the Toyota 2008 model year.

    You see after 2005, it seems that updates are required for each year and also in your case a Toyota update is required.

    The scanners can cost $1500 from Sears for each model year update and then that may only cover domestic vehicles, and a separate update for Toyota is required.

    So, I think that if you are looking for a solution, that the dealer is the best place to go for past 2005 vehicles and less than 10 years old.

    Again, good luck on this repair.

    I was always taught in auto technician school that the dealer has the best training and equipment for a given make of vehicle.

    So, a GM dealer is good for GM vehicles, Ford for Ford vehicles, and Chrysler for Chrysler vehicles.

    The same goes for foreign makes like Honda, or Toyota or Nissan or Mercedes Benz. as examples As, maximum amount of money and effort are put forth for any given brand.to get the best service and know how and tooling for any given make.

    Again, I hope you can get your engine started with a minimal amount of assistance.

    Although, I have a Toyota brand expertise badge, it is due to helping people with conventionally powered Toyotas rather than the hybrid vehicles, of which, I must admit I am not certified in in any way.

    Special training is required for the Hybrid Toyotas, and a separate course of training is required to work on those vehicles.

    I am formerly ASE Certified as a master auto technician from the year 1992, but have since gone on to other businesses.

    Back then, hybrid vehicles were something from the future, so, I do not know all of the DTC details for getting the immobilizer to work to not block the starting of the engine. It was just something that I learned about by looking at the electrical schematic on the Chilton based website I use as a primary reference.

    I'm learning about Hybrid vehicles, myself, as I research the newer models that are powered in this manner.

    So, in summary, I would say that the dealership is the best place to find certified Hybrid vehicle technicians, although it may be more expensive to go through them.

    I hope you can resolve the problem with the Toyota Prius not starting the engine.

Have both your battery and alternator inspected. Turn it on, disconnect your negative battery cable, if it dies, you need an alternator, if not, then you may want to test your battery for bad cells.
