So recently I bought an Aurora and it was working well, until one day it shifted very hard and tached out. I read the OBD, and it said that my crankshaft position sensor was bad. No biggie, I replaced it and had no more issues for a good amount of time.
Then one day, while driving it became stuck in one gear, and after turning off the engine, wouldn't turn over.
Here's where it gets weird, because it gave me 5 OBD codes all of which seem almost totally unrelated. Here's what I got.
P1860: TCC PWM Solenoid Circuit - electrical
P0340: Camshaft Position Sensor Circuit
P0385: Crankshaft Position Sensor B Circuit
P0753: 1-2 Solenoid Valve Control Circuit
P0122: Throttle Position Sensor 1 Circuit Low Voltage
So I'm left with many seemingly unrelated codes? I can't find a wiring diagram online to see if they're all on one fuse or something. Any help?

Yeah I cleared the code each time. As for which wiring diagram I'd need, I'm not entirely sure to be honest.

Being stuck in one gear night indicate a bad vehicle speed sensor.

Mine did something similar. Same car, '01, 4.0. TCC code, crankshaft sensor code, MAF code (replaced), outboard speed sensor (replaced). I fixed the speed sensor and windshield washer hose one night and left the hood up because I didn't see a light to drain the battery. The next morning the battery was dead. So I charged it up and took off to test the speed sensor. Another day shortly thereafter I went to leave and it wouldn't start. Just sat there clicking real fast. Dead battery. I charged it fully and had it tested at Autozone and O'Reilly and it tested good at both places. So since then I bought the internal speed sensor because the speedo was still acting up a little, and crankshaft sensors, the oil pan and lower block gaskets and when it warms up I'm going to pull the engine & trans and change those parts too. When it was running it ran like brand new, shifted like brand new and I hate to take it out but that oil leak is pretty bad.
There's a guy in Lansing (MI) that has a video on YT about this engine and he told one of the people commenting that it would be around $2,500 to do the gaskets. I didn't pay much more than that for the car, I can't afford that bill too so I'm going to do it myself. Fortunately I've done a lot of this type of work over the last 45 years so I'm not worried about screwing it up. I'm just hoping my body holds up!!! lol

I will, it will just take me a while. I turned 60 this year and am still recovering from my 5th aneurysm repair in my lower body. I can't do any heavy lifting but I have the equipment and my brother has a cherry picker. If I need some muscle I can call my nephew. I figured out several years ago how to work smarter, not harder out of necessity. It's a b**** getting older! lol
