MY HERO

Hey guys...I purchased this because I started getting a S 636 code on m XU6168 and the tractor going into limp mode. Tractor is a bit past two years old with about 400 hours. Called the dealer, he said the code indicated a bad crankshaft position sensor. He told me that he did not have any in stock and would order the only one in the system, that was two weeks ago and still no replacement part has arrived.

In the mean time I did purchase the scanner and so far I'm very happy with it. The site contacted me to confirm if I had the 16 port OBD II connector, before they would send it. This morning I went out to start the tractor up with the scanner hooked up, took about 10 minutes before the S 636 code happened. Looking at the scanner it says P0374 "Timing Reference High Resolution Signal A No Pulse."

At this point I find it hard to believe that there is not an alternative position sensor available. Anybody ran into that sensor on this tractor yet? Tractor's not doing me any good sitting to not be used for work.

That is great you LS owners can get a scan tool for your tractors, without having to spend too much. I wonder how many other makes of tractor you can get such a tool. I would like one for my ATV.

Anyway, not so good that finding a position sensor is hard. I would look into finding the part from or for another engine from the same maker. Maybe even directly from a supplier in the country or origin.

Are LS engines made in Korea?

OK folks..following up on my last post. A few days after my post the dealer called me to let me know the crankshaft sensor came in. I successfully installed it and no longer have issues.
I will say that I found the sensor on the engine block side behind the starter. I found it easier to just pull the started off, only two nuts holding it in place on my tractor.
Once the starter was out of the way it was a simple unscrew the 8mm, I believe, bolt, disconnect the harness and pull the old sensor. Make sure to check that the old O ring comes out as well, I had to get a small pick to pull the old one out.
Afterwards, just reverse the order and you should be good to go.

Sorry to ask again but I am trying to find a way to read codes on my XR4046. Has anyone had success reading codes with this scan tool? Thanks

If you still have the old sensor look for numbers on that, you might find the OEM number and buy it a lot cheaper. Seems that quite a few things on the LS Motor are Hyundai or Kia parts, not surprisingly. Once you know what it is you may find some reasonable aftermarket items.
