Crankshaft sensor on 2005 Altima

We can't seem to get it - it seems to be in a tight spot. What is the best way to reach it? We can feel it but can't seem to unplug it and we can't take it off with out unplugging it because the bolt is so close to it. Any suggestions would be greatly appreciated!!!

Those sensors are very hard to get out. I get that one from top. you need to remove the black engine cover and air cleaner top section with the tube, that goes to the throtlle body and than look down inthere. Look down right by the throtlle body. use flash light to pinpoint sensor. Once you see it, you need to push in the green sliderpiece thats inside the connector. make sure that the slider stays pushed in (they normally do) and get pliers and grab the sides of the connector and pull. it should come off. remove bolt and do the same thing to the sensor. Grab and pull.you may want to give it a little twist to help. Clean sensor connector with brake clean as you will most likely find oil inside of the connector. reverse instalation of new sensor. spray some lube onto the seal of sensor to ease insalation. re-assemble vehicle. on the way back the GREEN SLIDER needs to pop out or the sensor could unplug. again BARE to replace.good luck.

Tips for your 2005 Nissan Altima 2.5 crank shaft sensor


If your 2005 Nissan Altima is sputtering or seems to stall in mid drive at speeds of 55-70 mph or just shuts down at low speeds or idle this may be due to your crank shaft sensor.
The crank shaft sensors were originally made of plastic and were later "upgraded" to a metal sensor.
To change you will need a 10 mm Hex socket wrench, a long flat head screw driver, and if you have access I would recommend a lift.
To access the sensor you will be under the vehicle and you will see a guard plate over the exhaust, remove this so you can have some arm room to reach up behind the engine. reaching up with your right arm you should begin "blindly" feeling for the sensor which by looking at the new one you can be able to tell what it feels like. There will be the connector you need to detatch be careful not to break it. Once you locate it use the wrench to remove the bolts and the flat head to help wedge it out. Once the sensor is out you
Once you remove the old sensor the new one will be a tight fit but it does fit, be sure to attach the sensor cords before putting the new sensor back in. but once you have it attached take a little oil and lubricate the sensor to help it slide back in, reattach the bolts and now your done.

Where is the crank sensor located I need to replace it


Hi, behind the engine (driver's side), mid lower part on the engine block near the transmission. In order to access, you must remove the intake air hose. It will be hard to see it, the only way is to reach down and feel for the electrical harness that connects to it. hopefully this helps!!

You can also locate it by viewing this link..

Crankshaft and camshaft sensors location in nissan altima 2003


You are incorrect sir. There is a very good Youtube video showing you exactly where it is that is how I changed mine. The Crankshaft is located behind the engine block below and around from the cam sensor which is easly spotted looking at the engine. The crankshaft is in a difficult spot but once you figure out where it is it's easy...ish hope this helps

Nissan has reproduced the crank sensors installed in all altimas 2004 and up. it was deffective. Its also sort of difficult to access. take off the intake tube, dissconnect the throttle body connector. and reach to the bottom of the engine right next to the motor mount.take the connector off and see if the feel for oil. There will most likely be oil on the connector. Replace sensor

Crank shaft sensor


I have 10 years experience in a Nissan dealership and I know without a shadow of a doubt that the Crankshaft Position Sensor is NOT located next tp the crank pulley... it is rather at the other end of the engine near where the transmission bellhousing bolts to the engine block. It is on the side toward the firewall near the bottom. Even if you can get the vehicle on a lift and get under it, you can't really see it... It's more of a feel thing... There was a campaign (recall) on these engines to replace Crank Position and also Cam Postion sensors. Check with your dealer- the campaign might be open. You will need your VIN number when you call.

Crankshaft position sensor


Crank position sensor on a 2000 Altima is inside the distributor. Your model car does't have any other sensors (cam sensor). All inside the distributor.
