Beretta705

If anyone would like to sacrifice 5min to unplug there's and show me the correct color wire to which location on the plug It'd be appreciated

That's the issue which color wire is VWU

That's the issue which color wire is VWU

I mostly work on Prius but I also rebuild HV traction batteries but I do appreciate your concern so many people don't realize what they are playing with

Ty again Chris for all your help Is there anyway to determine WVU there's no marking on the wiring or pump

This may be one of my issues When I received the used pump the connector plug was broken so we took the plug off the old pump and put the wiring on the used pump back In too the old connector I'm wondering if the wires are in the wrong order Pictures included in the plug itself which wires are in which spot

You or anyone else wouldn't happen to have a wiring diagram for this car that will show the grounds would you I'm still having issues tracing it back to figuring out the issue Cleaned all the connectors I'm getting good voltage. I still can't activate the pump using the Techstream utility without getting a fault P2797 865

I appreciate the write up I am a prius mechanic mostly and know them well. I ran the techstream to turn on the pump through the utilities program but I keep getting a error code same as before with the other pump and driver. Also when I refilled the transmission I used a fluid transfer pump and filled till it came out of the fill plug. So what you are saying is it could be a air pocket in the system, or an electrical fault on the units themselves. I will look to see if there is an error code later........ ty

I have now replaced both the driver and the pump and changed the fluid. At no luck im still getting the same code and limp mode and don't know what else to do. I'm now only getting P2797 and the trans rattles at startup and shut down Any options or opinions would be appreciated

Im just hoping that's where the temp sensor is and its not the sensor on the bearing in the manual pump body

Ty sir

Hello John Thats what I was thinking and the pump looks corroded externally I don't think it has any issue with the actual control module itself as its receiving 12 volts nominally at the pump itself I figured its an internal issue. What would be the best way to diagnose the issue before replacing the pump itself? Also is there anyway to check the transmission fluid level I was wondering if it was also low as a fault

I have a 07 GS450H thats throwing the code P3176 It says it the oil pump temp low and its not allowing the hybrid system to come on it is also followed by C1259 and C1310 codes please help
