crankshaft poition sensor

I just removed mine last night. Unless you want to take a bunch of stuff off, including your entire intake, you have to go in from underneath. The best way I can describe it is that you have to look in where your oil filter is on the back of the engine. From there look left (towards the driver side), under the starter you'll see the harness. Remove the harness and you'll barely be able to see the bold on the other side. You should be able to squeeze a ratchet in there to remove the 10mm bolt. Then it gets interesting. Mine was very difficult to remove due to the small space. I used a thin tipped screwdriver under where the bolt was to wedge it out a bit, stopping after a minute each time to turn and pull with my hand. There's not much room for leverage, so I twisted it gently to pry the sensor out. After it came out a bit I used a wider tipped screwdriver, and eventually worked it out far enough I could pull it out by hand. You have to turn it 180 degrees to get it past the bracket. I also found that wiping my finger around the inside of the hole to clean out the rust made the new one go in easier. And, unless you've had the specific 0335 code come up, try the camshaft sensor first. That is on the drivers side of the engine near the top, just above the thermostat housing. It's the exact same part, so if it doesn't fix the issue swap it back out and explore the underbelly to find the crank sensor.
