Replacing the MG1 current sensor in the inverter fixed the problem. Thank-you to everyone that has been so helpful. Attached is a picture of the...
I have been posting about P3125 fault which is inhibiting ICE from starting. During this time I have been charging and also testing the traction...
I have been posting here and on a Prius technical yahoo group and have been getting excellent support from people in this group and from...
I jacked up the car, thinking I could put a scope on the MG1 and MG2 positions sensors, see if I can see a problem with MG1 and maybe even get the...
Thank-you for the suggestion. I will buy a different scanner, if it actually works. I didn't understand what XGAUGE is. I clicked the link and...
Thank-you for the response. I asked them on Friday what they would charge to come out here and read the code, I'm about an hour from their...
Unfortunatly it does not. What it does is to read 94 from who knows where and displays that. If I force other errors, for example unplugging HV....
I'm still trying to get my project 2001 Prius to attempt to start the ICE. I can drive the car around electric only, so MG2 is OK. I see a pulse...
Re: Gas engine does not start - inverter schematic? That is a good suggestion. I was going to try to expedite the return of the code reader...
I just ohm'd out MG1, connected to the inverter, no surprises. Very low resistance across, U, V, W and and about 1.3 MOHM between each of these...
Thank-you for the suggestion, but MG1 isn't spinning the ICE. I think that was what someone was telling me about the fail safe condition. It...
Scrap that about 2 MG1 connections. I see them there are 3, they come up from underneath the front of the inverter. I will try to ohm them out.
I was guessing the same thing, and thinking about ohming out the leads to MG1 to each other and to ground. It looks like the inverter has 5...
Could you please explain what a failsafe condition is? Will that stop the gas engine from starting, but allow me to run electric? I explained...
Thank-you for posting the pictures. Regarding fuel pump switch. I don't believe that it has been in a recent accident. Is this correct...
Thank-you, that was a good idea. The engine turns by hand easily.
It never tries to crank, the gas engine pulley does not budge. What I do know works is the part of the inverter that charges the low voltage...
Re: Gas engine does not start - P3125 I borrowed a code reader, only code was P3125, with notation of SMR. The code reader did not have the...
Thank-you, I will look for the ECM. The power steering does work, so it must be there.
Yes, I replaced the bad cells and charged the HV battery, and can drive it electric only. It just won't even attempt to start the gas engine,
