Crankshaft position sensor on 2000 Northstar engine


Recommended Posts

Can anyone tell me where the crankshaft position sensor is located on a 2000 Deville DTS with the Northstar 4.6 engine? I want to check the connection for possible water and/or loose connector. Have never had to do anything

with this engine and not sure exactly where to look for this sensor.

If I am not mistaken, there are 2 of them located one above the other on the underneath of the engine. They are on the front, behind the front motor mount, and up and to the right of the oil filter if you are looking from underneath. You should see 2 plugs, one above the other. Those are the Crankshaft Sensor plugs.

Thanks Carla, As soon as I get a chance I will crawl underneath and check it out. I am hoping I simply got a little moisture in there after taking the car through a touchless high pressure car wash that also sprays the underside of the car.

It's running just fine (I only have 28,000 miles on it) but the "Service Engine Soon" light comes on and it's indicating a problem with the crank sensor.

You only have 28,000 miles?? Wow! I wish I had that!

They are above the oil filter adapter which has to be removed to get at them. May just as well replace them. GM had a bad supplier from 2000 to early '03 and if they are original you'll have to do it later anyway.

dont replace with ones from mexico. Standard brand makes ones made in japan and also the dealership should have the good ones. They range from $50 standard -$75 dealership each. It may not be the use length of them with your low miles, it could be they are 10 years old.

Facing the front of the engine, the crank sensors are to the right and above the oil filter adapter. I believe that it is easier to get at the crank sensors by removing the oil filter adapter, buy new seals for the adapter if you take it out

Thanks to all of you for the quick response to my question. I am brand new to this forum and plan on logging in frequently. I will try to get under the car tomorrow to check out the sensors. Glad to hear the advice on staying away from

the cheap brands. Thanks again!!

There are 2 sensors and they are mid block left side.

I was originally planning on tackling this job myself but my schedule became too busy so I took the car to my local mechanic who replaced both sensors today. Computer scan showed problems with both of them so we decided to

replace them now instead of waiting for a major meltdown! Engine is running fine now,

Thanks to all for your advice!
