Service ESC (Code C0051-1A)

Had a tie rod go bad after 40k miles with a Ready Lift 2.0 sst kit installed. The shop that I took it to said the previous shop cut the driver side inner tie rod when installing the kit. After getting a new inner and outer tie rod installed, my truck now throws service esc code c0051-1A. The alignment shop tried to relearn the steering wheel angle sensor but had no luck. Dealership tried as well with no luck. Said I need a new rack and pinion. 

 

For context, my steering wasn’t straight after the first alignment. It was a tad to the left. The new alignment shop said they could straighten everything out, but the sensor is reading 37*. Also, I get 1 1/2 full crank to the left and only 1 1/4 crank to the right when turning the wheel. 

 

Is a new rack and pinion needed or does it need to be recentered correctly?

if the code was not there before the work was done then they screwed something up. wrong parts maybe. one of the old tricks alignment shop used to center the steering wheel was to screw with the tie rod adjustment, which you can't do anymore because of the steering sensor. i would say the rack needs to be centered and then the wheels aligned. this is a common code when ever front end work is done

Had another shop take a look at it today. Alignment is spot on, but now they can’t even gain access to the steering wheel angle sensor module. 
 

2 shops and a dealer haven’t been able to relearn or recalibrate. Just my luck

Sounds like the rack is damaged, possibly from working on the inner tie rod.
