Check engine light keeps coming on?

[CBrabec]

My check engine light keeps coming on when I run my truck hard or I'm plowing snow. These are the codes I get:



P0602: Control module programming error/not programmed

P0541: Low voltage on the #1 intake air heater relay

P0336: Crankshaft position sensor performance



Code the smarty caught:



P0201 Fuel injector 1 circuit



The smarty cleared it's code, but the other (3) keep showing up. Is one of these codes in particular causing my check engine light to go on? What is the best method of getting rid of these codes? These codes aren't hurting my trucks performance, just an annoyance. If I start my truck and shut it off (3) times, the check engine light goes off. Any help would be appreciated.

I used to get the P0336 when plowing. Some one said it was from lugging the engine, so whenever i'm plowing I use 1st and the light never showed up again. Dont know how yours could lug though, since it a auto. On a side note everytime I hook up to the plow I get a CEL and 3 codes. I forget the other 2 but the 0336 rings a bell. I have since turned off the tst and use first gear when starting, and no codes yet.

What plow are you running???

BOSS 8. 2" V. Wonder if I need to take it to a dealership to have the codes removed. Like I said before, no engine problems, just an annoyance.
