2001 nissan sentra crankshaft position sensor location

Hello, my first posting. My sister-in-law has a 2001 Nissan Sentra SE which I believe has a 2.0 liter motor ("B" in VIN). Every thread I read asks about the location of the crank sensor on a 1.8 liter motor. Is there a thread here somewhere describing the removal and replacing of the crank sensor on the 2.0 liter motor? Thank you very much. These cars a re new to me. Ody

I'm not sure if it's the same location in your country as it is in North America, but over here the crankshaft position sensor on a 2001 Sentra SR20DE is located on the transmission bellhousing near where it bolts to the engine. It is on the top side, but slightly towards the radiator. It'll be held on by a single, 10MM head bolt.

Thanks for the location. Now we finally have some trouble codes, 325 and 340. I find camshaft position sensors for sale at places like Rock Auto online for about $30.00. However, the factory service manual states the sensor is part of the distributor and the distributor is not repairable. This gets more confusing all the time. I'm almost thinking the sensor for sale on-line is not really a camshaft position sensor but rather a crankshaft position sensor (see attachment). Still more confused than ever.

The camshaft position sensor is located inside the distributor on the SR20DE and is not serviceable; the part you are showing is not the crank position sensor. The crank position sensor is rounder and longer as pictured below. From Rockauto, look at NTK EH0226 (manual trans) and NTK EH0225 (auto trans) for examples.

Thanks. If you re-read my post above regarding the sensor, I referred to it as a "camshaft position sensor" (not crankshaft). And the same photo I posted from Rock Auto was listed for a 2001 Nissan Sentra with 2.0 as a "camshaft position sensor". That is either a listing error or ? That is why I still am trying to sort this all out. I know the factory service manual says the distributor is not repairable.

Many later distributor-less models use that sensor style for the cam, and there are even instances where a crank sensor on one model is used as a cam sensor on a different model or vice versa. On models that lack distributors, both types are almost always Hall Effect. So you can't go by those sorts of descriptions, what matters is the Nissan part number and equivalence.

Good to know, I'm glad you responded ("technology is advancing too quickly for me). Makes me wish the old point/condenser distributors would return once again.
