I changed the camshaft position sensor and crankshaft position sensor last night.
The camshaft position sensor was tougher than it looked to remove. I needed a deep socket to reach the screw but an extension wouldn’t fit without interfering with the manifold. Lots of brackets and wires were loosened or moved to get in there. It was tedious and delicate, but ultimately took maybe an hour, most of which was spent saying, “Does this fit? No... Does THIS fit? No...”
I very much doubt it was bad, but it was definitely not squeaky clean.
Next came the crankshaft position sensor. I would probably never attempt this again. Four hours. The path of the electrical connection is barely wide enough for the sensor. Far worse was the inaccessibility of the connection, unless I wanted to take off the entire exhaust manifold, which would require removing many other bits and boops first.
In fact, I dont even remember how I got this off... oh wait, yes. Yes. I reached from the bottom of the engine, on my back, up through and got about two fingers back there. I squeezed and giggled the plastic about 300,000 times. Came back up to pull the end connected to the loom. CLICK. I then pulverized the bracket holding the old sensor in at top. That was probably worse because it it truly buried. Anyway. Lots of cursing an swearing.
I left the old sensor hanging so you I could snake the new wire through the same path blindly. This was also hell. I had to cut it to get it out.
In summation, I hate everything.
