Citroen DS3 ESP Fault

Post by Digit47 »

Hi
Hi
Been reading a lot on this forum today and found it very informative,Thanks.
Anyway my daughters ran into a curb with her ds3 and her esp light has came on ,
I have scanned it with N Autel 805 and got a code c1136 steering wheel angel sensor signal coherence.
Also took a look under the car and she has bent the inner track rod on the near side so the wheel is noticeably not straight compared with the other side.
Should I renew the track rod first and then try and recalibrate the steering or replace the whole steering rack then recalibrate.

The electric power steering is fitted directly onto the rack as a complete unit. If a kerb or other impact has occurred on wheel, it can have several consequences, the obvious issue with the geometry on the axle, but could of had a 'ram' effect on the rack which in turn can have damaged the rack internals and the power steering as a result.

So my advice would be to correctly check any and all damage including the rack. The power steering also has an integral steering wheel angle sensor. So if this is now reporting faults, then I suspect the impact has caused damage internally - so does need to be properly checked and diagnosed.
Fault Code: C1136
Description of Fault: Steering wheel angle sensor fault. Coherence fault. The value of the offset of the steering wheel angle is greater than 15°.
