I will be driving along and all of a sudden I will loose all throttle and the engine check light will come on. Check the codes out with the smarty and cleared, today the dead peddle and codes repeatedly appeared after they were cleared.
P0121-TP sensor voltage does not agree with map
p0602-ECM fueling calibration error
P1693-DTC cleared in companion JTEC module

I think I have read that this codes are normal or is there something else wrong?

 

where is the help

 

I had a similar problem last month, and took out the power puck I had installed 4 years ago. After a battery disconnect reset the truck ran fine for 300 miles. Now all the same problems, no power, and unintended acceleration, with the one code being no camshaft sensor detected. The shop I use can check the sensor and get a feed, but the ECM doesn't recognize it. They are telling me they suspect the ECM is fried. I am hoping tomorrow to get some local help and more info. Whatever I find out, I will share.

 

Thanks for the reply this first happened when i installed the comp box with the wire tapped. Just the other day it was persistently happening and was getting annoying. Maybe i can get some time to take the comp off and just run the smarty and see if the problem still persists. Thanks for the reply and keep me informed sense you are the only one replying to this trend.
