Where Is the Crank System Located on a 1999 Nissan Altima

Nissan Altima Crankshaft Position & Camshaft Sensor Replacement Guide
Pictures & instructions on how to replace the crankshaft position sensor & camshaft sensing element in a L31 2002 to 2006 Nissan Altima.

Unkept Wire Connector This run covers the renewal of some the camshaft and crankshaft berth sensors since they are both identical.

Owners of separate 3rd generation 2002, 2003, 2004, 2005 & 2006 Altima sedans should find these DIY instructions to be helpful.

In the above row of photos you can see the location of the camshaft sensor on the driver's side of the engine and the crankshaft pose sensor is down feather happening the posterior side of the engine (best seen from under the car & removed from above).

To replace either detector you will demand a 10mm metric bolt and a ratchet wrench. Don't forget the rubber o-ring. You'Ra done!

Now for our saga. Happening a holiday weekend we discovered that the 2.5L inline 4 cylinder engine in the L31 generation 2002 Nissan Altima was leaking oil color.

Upon review of the efferent, my chum pinpointed the source of the oil wetting to be the crankshaft position sensor.

The ground that the engine was leaking oil was that a careless auto machinist neglected to instal an o-ring on to the sensor during the car's 60,000 mile service.

When replacement either sensor, be certainly to inspect the rubber o-ring and verify that IT is really connected the sensor!

The mechanic also moldiness sustain distant the wire harness connector with a screwdriver because it was much down apart.

Few compatible replacement camshaft posture sensors with their part numbers include the following: OEM 96239, Canonic Motor Products PC464, Nissan 23731-6N21A, Dorman 530-010 and Delphi SS10818.

Both replacement crankshaft military position sensors with their part numbers are as follows: Nissan 23731-6N21A, Wells SU6364, Standard Motor Products PC464T, Hitachi W0133-1796511-HIT and Delphi SS10816.

Connective From Junkyard We needed to get this car running today and the only selection was to visit a wrecked car parts recycling center, a.k.a. a junkyard.

Luckily the junkyard had a totaled 2006 Nissan Altima with the engine wiring tranquilize intact.

After we cut off the camshaft spatial relation sensor wire harness connective, totally we had to exercise was splice information technology in the lead to the '02 Altima with coffin nail wire connectors.

If you don't have a junkyard in your expanse, I recommend purchasing the OEM Nissan 23731-6N21A camshaft sensing element and also the Nissan 23731-6N21A crankshaft sensor.

Butt Wire Connectors
Wire Cigaret Connectors Crimped For the optimal electrical connective, I advocate using crimp connectors.

If necessary, you could also just twist the wires together, wrap them in electrical videotape and use cable ties to secure the tape.
