Not absolutely, it's a matter of dexterity I believe. If you can feel it, 10mm wrench I think I heard on here, it's just a matter of reaching around the starter.

I did it without removing the starter. Just keep your elbow higher than the starter.

or do it from the top by removing air intake, EGR, throttle cable bracket and maybe the TB and some vacuum hoses.

Default Re: Does the starter need to be removed to replace the CPS?

I just replaced this yesterday. It was surprisingly easy. No need to remove the starter.

Materials:
Creeper, large piece of cardboard, or old clothes (you will be lying on your back)
2 Ramps or Floorjack and 2 jackstands
1/4 drive ratchet
10mm socket (either deep, or short w/ extension)
small flat blade screwdriver

NOTE: Best to do this with the engine totally cool, as you will be essentially reaching around and probably leaning on the exhaust pipe.

Get the front of the car high enough that you can crawl underneath (supported either by ramps or jackstands). Chock the rear wheels with some wood blocks, chocks or otherwise.
Take all your tools, sensor and a rag to tidy up while you are down there. Lie on your back with your head towards the back of the car, feet towards the front. Your right arm should line up just to the right of the exhaust pipe. It should be an unobstructed reach up to the starter motor.

The bolt that mounts the sensor is directly above the starter, towards the right side of the starter motor. If you were to rest your right hand on top of the starter, and slide it against the engine block, you would probably bump the mounting bolt.

NOTE: Don't bother disconnecting the wiring harness until after the sensor is removed.

You should be able to fit the ratchet on the bolt with plenty of room. If you are right handed (which I am not) this would be even easier. Once the bolt is out, wiggle the sensor to free it up, and pull it out. The mounting flange that the bolt goes through creates a clearance problem when you are pulling the sensor out, so rotate the sensor so that the flange points towards the passenger side of the vehicle when you remove it.

Once the sensor is out of the engine, there should be enough slack in the wires that it can hang down in sight. Use the screwdriver to pry off the harness. Attach the new sensor to the harness, re-install the sensor into the engine, the bolt into the flange, tighten it up about as tight as you can make it using only two fingers (torque wrench won't fit), and voila!! Wipe off any crud while you are down there so you can hunt for any oil leaks next time.

REWARD EXCELLENCE!
