I could not find an exact video for this engine but I attached a picture of the location It is on the driver's side of the engine at the back by the flywheel.
Why are you replacing it? Do you have a code?
The other issues you have are not affected by this sensor.
It sounds like the starter solenoid is not releasing and the starter may need to be replaced. You should verify power is not to the solenoid when the key is in the on position.
Can we start with the original issue?
