Default DIY-Crankshaft Position Sensor

I consolidated my experience changing a CPS on a 2004 xB 1.5l 1NZ-FE:

Why did you replace your sensor? Mine is all gunked up with oil and I have P0012 error.

Also do you have to drain the oil before replacing?

Here is the part in question. I cleaned it off a bit and got a better picture. Is that the crankshaft position sensor. The harness also doesn't look that good.

You are correct that that is the crankshaft Position Sensor. You do not have to drain the oil to replace this.
I did not have a code but I bought the vehicle used with 130K and did not know how hard that little motor was made to work. I did preventative maintenance and among other parts I changed this and the VVT solenoid which could be your code source. The VVT solenoid will cost about $60 at this time, no need to change the oil, and is super easy to change.

-- Reactor - Senior Member says "P0012 means: Camshaft Position "A" - Timing Over-Retarded. This code is not an indication of a bad camshaft position sensor. For that we have P0340"
-- Here's your P0012 code explained and it mentions the VVT (or VCT) solenoid (code P0010) as a probable cause:

If you decide to change the VVT solenoid,

Thanks a lot! I already did the OCV sensor swap so VVT and CPS will be next on my list.

Do you have part numbers available?

I'm sorry but the part costs twice what I mentioned previously. I'll edit the post.

Here's the part I installed a year ago and since then no issues with the part:
STANDARD MOTOR PRODUCTS VVT162 {#1533021010, 1533021011, 1533021020} (Standard Replacement

Here's where I got it from:
https://www.rockauto.com/en/parts/st...actuator,12910

here's a general description of that product:

No worries, Iíll probably pick it up on eBay which their sales lately I should get a good discount. Do you also have the crankshaft position sensor part # handy?

I was looking over the posts and if you replaced the OCV (oil control valve) you've replaced the VVT solenoid - same part different names.
In the second video at 4:20 take note of the mention of an 8mm hex bolt filter beneath the Oil Control ValveToyota 15678-21010 Oil Control Valve Filter

This will be the worst case for the P0012 :

Yes, I already changed that and cleaned the filter too. No go. I noticed the gunky crankshaft position sensor so I'll do that and see if that makes a difference. Otherwise, I have a case open with Toyota about the P0012 but that would require me to go to the dealership for an inspection.

Thanks for sharing the part number. I ordered it already and will hopefully have it replaced later this week.

Do you know anything about the Crankshaft Position Sensor wiring? Should I replace that wire or just clean it off with some simple green?

I'm not sure if it's the angle but the OEM crank angle sensor on my picture looks like its connected to a large nut. Did yours look like that?

Okay. The part posted a picture of was not the Crankshaft Position Sensor, and I still don't know what it is. However, I did replace my crankshaft position sensor since I was there. Good thing I did, here's what it looked like:

I cleaned up the other sensor from the outside. I couldn't even get the locking mechanism to budge because the wiring is so snug. I'm still trying to figure out what this is and if it's easily replaceable:
