Hello all 
My brother corsa c had probleme in eps 
While driving the eps light come on and steering became very havy 
Turn car off for about 5 mn start car eps work great until the next same problem 
I diagnose the probleme i have p 1502 ( difference between torque and main sensor not present i clear code i purchased used eps motor and eps ecu also same probleme tried to calibrate succefull 
I realised if i turn car on and not touch or go in car i don't have a probleme 
If i hit the steering even the car is park or go on a ride with it the eps light come on and same prob 
Any infos will be much appreciated

In which ecu is that code from and what kind of reader have been used?

The code is from eps power steering module
With opcom and x431 same code

Hmm    check the wiring m8 between the 2 sensors it's probably wiring issue as you've replaced parts
