P 0201 '03 HO

From : fmb

Q: i have gotten this code usually after or during wot to get on the freeway. engine seems to run smooth when not excellerating but seems to miss at wot or even accellerating at less than wot. p-0201 = fuel injector 1 circuit. ive cleared the code and the truck runs fine till i wot a few times. it doesnt always happen with the first wot but it has occurred 3 times in the past week. is there anything i should look at before taking it in to the dealer almost 98k miles on it original fuel pumps. along with that code i get the p 0633. tia fmb .

is there anything i should look at before taking it in to the dealer almost 98k miles on it original fuel pumps. nah - youre still under warranty just so get it to the dealer before you roll 100k at least to get the problem documented. anything fuel-injector-related can run into significant $$$. hopefully you dont have any aftermarket boxes or programmers installed and can present a completely stock engine to the dealership for diagnosis/repair. along with that code i get the p 0633. do you have the sentry key system big thick gray-handled ignition key - if so its not working. tell the dealership about that as well. thats just a simple programming task to reset the encryption key in the pcm .
