  • Hi Everyone: Here is an example of very poor quality workmanship on the installation of the crankshaft position sensor. Further when you have codes PO335 and PO725 always replace the crankshaft sensor first, make sure to check for oil in the connector and clean it up before installing the sensor or you will still have a problem. The Nissan dealer informed me the Camshaft and Crankshaft sensors now have the same part number. Please be careful when you have to work in these restricted area's to make sure you don't cause more damage doing the repair as in this case. For more information be sure to visist: www.johnsadlers...

    Thank you for that explanation. Ive replaced both crank and camshaft sensors and it wasn't any fun.

    the people who design all these lock tabs suck, cost us time and money.

    Woulda been nice to see where the sensor goes into, in the block,not just show the wiring and the defective part.

    I changed mine and the problem I have is that the harness connector clicks into the fully extended position so that the edge of the green tab is is flush with the connector housing but it won't lock, you can tug it right back out. What do I do?

    • @JohnSadlersAutoRepair
      @JohnSadlersAutoRepair  10 лет назад

      When you push the connector on, the green tab must be pushed in. It will actually stay in place in the pushed in position. Then when you push it all the way onto the sensor it is supposed to pop up to the flush position. When your pushing it on you may have to put a little side to side pressure to make it release the lock. The one I did, dad the hold the connector pushed in and took a long flat blade screw driver to pop the green tab up. If none of that works, will have to find another connector.

      sticker with part number on the outside? if yes leave it on. There should be nothing covering the tip of the sensor, the opposite end of the wiring connector.

      Hi Noe! Since the connector was not all the way on the sensor and the sensor was not all the way in the block there was no need to Waste my Customers Money doing further testing.

    Unfortunately, that connector is prone to seize with time. The slides oxidate, and get full of dust and grime through the years, and due to it's location, makes it very difficult to clean. Even if you are careful, and diligent, it is not uncommon to break the lock on the connector, and Nissan does not sell it separately. It comes as an entire assembly with the harness. They want 1600.00 for a harness. It's a crappy design to say the least. On some vehicles, like the Maxima, it actually doubles up as a shielded harness which piggybacks into the main harness. Again, Nissan won't sell it separately.

      Wow Danish! Your so Smart! I'm proud to know you!
      Once you retrieve codes the next logical thing to do is look physically at the concern.
      When I found the problem you like so much in the video, the next logical thing to do is put the vehicle back to a factory standard and retest.
      It's really great to know you spend your time testing damaged components.

    Beware of most aftermarket sensors. I’ve replaced many of these over the years in our shop and they often fail or cause other codes to be triggered. You’re not saving money by buying an aftermarket sensor - it will wind up costing you more. The situation is worse with the sensor connector. As far as I know there is no oem connector available and I’ve only found two vendors who sell 100% reliable connectors, Look here: www.bonanza.com/listings/503762340 or here www.ebay.com/itm/381951393669. All the other connectors out there are Chinese junk which often fail right out of the package. The sensor connectors go bad often and cause a code to be triggered. Over time they no longer make a good electrical connection with the sensor due to oil and dirt contamination and fatigue. Before you replace the sensor try cleaning the connector with brake clean or something similar and compressor air. If this makes the code go away then you will need to replace the connector. Cleaning it is only a temporary solution and it will likely fail again soon.
