Separate names with a comma.
Yes, it's a complicated issue potentially since there are several things that can cause that error. I had the manual and did the steps and found...
My bad. I had too many things floating in my head when I wrote that. I meant that they fried the thing behind the black round cover at the back...
I'm sure they'd rape you out there for it. Many places here probably would too, even though the labor rate is much lower here. I'm sure glad...
SOLVED!!!! I took it to a local Prius specialist and they eventually found a bad wire to the transmission resolver plug. They said it was very...
Thanks for the explanation. That all makes sense. So it seems that by my readings there's an open circuit in PCON and PPOS. Still have no idea...
I was hopeful but today it didn't happen like that. It was 84 degrees and I put the hair dryer on the Power Source Control ECU and connectors for...
Ahh OK. So that would mean that the resistance is uber high on those wires, and since Toyota says they should be above 10k ohms, these are not out...
I MAY have stumbled upon something today. It was 84 degrees this afternoon. That's lower than what would normally set off the P lock error...
Today I ran the P3102 diagnostics again because now I know what "OL" means. When I posted about that yesterday was interpreting OL to mean HIGH...
OK Gotcha. I actually did that the other day and posted the results in message #54. I tapped into the back of pin 13 on the TCU "It only varied by...
Those positaps would be great to have. I can't find any locally. Auto zone has these which should do the trick. But they don't look removable like...
Good idea. Not sure how to do that though. I assume those buzzing circuit testers would need to be connected to two points, but which two? Would...
After the above testing...Today was 88 degrees and 90% humidity. I ran the car in the driveway with the AC cranked, planning to drive and see if I...
I couldn't find the J14 connector. It must be behind the AC vent box and I didn't want to take that all apart. I did the PCON (H17–9) or PCON...
OK thanks maybe I'll be able to find it. I know roughly where it should be and I see the shape of it on page 384. I just saw the drawing of a...
Yes, pin to ground and both connectors disconnected. I think I get what you're saying but maybe not. The wiring chart on page 262 shows H17-9...
Gotcha. I didn't mean for that to come across like I was threatened by it. I was just asking to learn if I should do it differently. The J14 is...
Do you think I tested wrong? I followed the repair manual: (f) Check the resistance between the wire harness side connectors. Standard (Check...
I THINK I MAY HAVE FIGURED SOMETHING OUT! First, I checked pin 13 without the P lock error and the voltage was fine--13.88V with the power on....
Yes, I read that thread and I did check pin 13. It had 13.88V. I said that I tested it in post #1, but I didn't say if I tested it when the P lock...
