Unknown code?

Crankshaft position sensor A circut range/performance. According to Autoenginuity library.
 
I see a TST listed in your mods. The TST has caused the P0336 code for years. Some trucks throw that code a lot, some every now and then and some never. Mine will throw it about twice a month. Never really affects performance, just a nuisance. I just clear it on go on.
 
Any mud or muck all over the tone ring and or sensor?

TST will throw it as well.
 
I get that sometimes with my TST if I get on it hard and the RPMs are below 1500. Just clear the code with Smarty and don't worry. Like others say it is very common with using TST.
 
No I checked it theres no mud or anything on it....must be the tst...but ive had it on there for probly a year and it just now threw the code last week.
 
Is the tst even worth me still having and running with the tnt on the smarty? some people say yes and others say not at all?
