Hi,
I wanted to tell you that something unusual happened. I left the 12V battery disconnected and connected it again yesterday. At first, it worked for a few minutes and then stopped, so the 12v reset didn't work. I decided to measure the sensor, and although I don't have an oscilloscope, I measured one side, rotated, measured again and repeated the process. The voltage on each channel was at 5v and then dropped when turning the shaft; it seemed that the sensor was fine.
Then I thought about measuring it in motion, since it is a square signal, it should show approximately half the voltage on each channel while it is running, and indeed it was around 2.5V on each channel. Before turning it on for the test in motion, I decided to push the low voltage connector of the inverter (where the signal from this sensor comes in) to make sure there was no false contact. The second time I turned it on after moving the connector, it worked for two hours. I turned it off, turned it back on, and it worked fine for another 10 minutes; I turned it off, turned it back on, and it worked for 20 minutes.
I tried it this morning, and it failed after 3 minutes. I pushed the connector back in, and it's been working for about 45 minutes now.
I think it might be a problem with one of these two connectors or the wire that goes to them. I had previously checked the internal connector, and although the solder joints looked bad, and I got a bad continuity reading at first, when I tried to confirm the bad continuity, it no longer showed continuity faults, so I ruled out that it was bad. Also, since the connector is covered in a transparent soft gel, re-soldering it is not easy, so I assumed it was good.
Long story short, sensor voltages are ok, i suspect the connector on the image is bad. Even on this image that is for an item on sale the welds looks extremly bad like mine.
@asavage After your car failed, turn it off and then could you please try to unplug then plug again(or just push it) the low voltage connector the one on that is near of the high voltage cables on the DI. then turn it on and test it again.
