I bit the bullet, and ordered some parts from digikey for my pedal. I was concerned about the pedal failing and causing the truck to go full throttle. (even though a failure will most likely result in 0V)
After stripping it down to a bare PCB, and cross-referencing the Chinese knockoff part in google, and comparing it's output to real Honeywell parts, I ended up on the SS490 Series sensors.
I purchased a few parts of different sensing ranges, and found that the SS496B is the part. The fake part is labeled 96 B, so that at least helps to confirm I have the right part.
It is a direct drop in replacement part. Same pinout, same voltage range. I did however find that the usable range on the pedal is better now. There is less dead-zone at the start, and the end of the range. As well as the off-pedal voltage is 25mV lower with the genuine part, and the pedal has more physical travel before the voltage saturates at 4.89V. (4.9V on the fake part) Just put the new part in the same spot, with the same gap to the magnet and your golden.
If you have a JT-2D Pedal die, don't toss it... Get a cheap part here (or any other vendor selling the SS496B)
Honeywell SS496B-T2 (the T2 just means the leads are formed, you need to straighten them)
Digikey Part Number: 480-6213-1-ND
Here is the Digikey Link to it: http://www.digikey.com/product-search/e ... -6213-1-ND
The install is pretty straight forward, so I didn't take pictures or write a how-to. But I will write something up if anyone needs it.
