Replacing the crankshaft position sensor can be done from the engine bay, or underneath the car. Replacing it from underneath is significantly easier and faster.

The crankshaft position sensor is located underneath the starter and is held in with one E10 bolt and one electrical connector.

Unplug the single electric connector on the sensor by lifting up on the retention clip and pulling the connector off.

Remove the single E10 retention bolt.

The best tool setup yo extract the E10 bolt in such a tight space is a ratchet with a skinny E10 socket, and short extension attached to it. A swiveling adapter can make the job easier but isn't required.

Remove the old crankshaft position sensor by using a pick-tool or flathead screwdriver and carefully wedge it underneath the sensor while you wiggle it out of place.

Congrats! Your old crankshaft position sensor is removed, now time to install the new one.

Install the new crankshaft sensor where the old one was removed.

Align the new sensor so the retention bolt hole lines up with the threads on the engine side.

Handthread the sensor retention bolt into place to fully align the sensor to the engine.

Hand-torque the sensor retention bolt so the sensor is snugly installed.

Re-plug the crankshaft sensor electrical connector until it clips into place.

Use a scan tool to clear all engine codes, to ensure the P0335 crankshaft position sensor code is gone.

To ensure there are no issues with the new sensor and the issue is fixed, test start the vehicle.

Congrats on replacing your crankshaft position sensor! Keep an eye on your check engine codes in the future to ensure the P0335 code doesn't come back, indicating a long-term issue.
