[Solved] Opel Corsa D Electric Power Steering: Sensor Issue, Calibration, or Replacement Options

Hello,
In my Opel Corsa D, there is electric power steering mounted in the steering column. The problem is too sensitive support. At a standstill, you can turn the steering wheel left and right without the slightest effort. When driving, minimal movement of the steering wheel and wheels shorten ... it is a bit like driving a go-kart.
After disconnecting the power steering sensor, there is no.
Do I have to replace the sensor, can gp regenerate or calibrate somehow?

You will probably calibrate with a diagnostic cable, but if you have already wiped the resistance path better to buy a new one. You can use the preparation for potentiometers but sooner or later the fault will return.

I will add that when I make a quick steering wheel turn, I feel a slight change in strength (or a crunch).
How can I replace this sensor? Do I have to buy the entire support mechanism?

the potentiometer sensor itself is probably located in the steering wheel near the direction indicator switches


When you unscrew the steering wheel you should have free access to it only before removing the steering wheel mark a line with a marker pen
under the screw so that you will not have the steering wheel turned a few degrees on the multi-line and you will see after the dash that you have inserted the steering wheel.



Here on the photo you can see that the tag is there but make sure you have it too. If you do not have to do so yourself
The control point of the potentiometer itself is also important when assembling it, usually the arrow is marked - it can be seen on the focuser with the levers on the yellow cube. After replacement, calibration with a diagnostic computer will be required.

This is one more question: how to remove the airbag from the steering wheel?

Usually screws on the back of the steering wheel or latches and you can pull out the cushion and there remains the detachment of the plug of the cushion (do not turn on the ignition without the cushion because you will have a pillow error and you will need to delete it with a computer). It's best to unplug the battery but look for the radio code first so that it doesn't turn out then you won't unlock it.
I do not have such a car so I'm not sure maybe you'll find somewhere a video from removing the steering wheel.

The steering sensor is unfortunately not in the switch module, just behind the steering wheel. There is only tape and cables for AirBag. The sensor itself is located at the power assist motor. It remains for me to dismantle the column with support.

Exactly in the EPS team. Contrary to appearances, you don't have to pull everything out. You can do it on the car with the right skill. Read about the exchange. Details are important.

The case looks like this:
Car electronics said the eps sensor was OK, suggested a problem with the engine or its control.
When spinning the steering wheel you can hear a delicate sound as if rubbing metal on metal.
I undressed eps and I was wondering if there were no control mosfets, probably engine speeds.

A basic note to your electronics. EPS (just like the whole car) is diagnosed with a tester by reading error codes. I would suggest doing this instead of divination with ... This crackling in your Corsa may be due to a malfunction of the Angle / Torque Sensor causing jerking of the rotation motor Sometimes the whole body can shake. Tester. Errors. Diagnosis.

The electronics technician diagnosed the power steering error using the TECH 2 tool. The new programming of the swivel sensor does not help. The steering wheel does not harden while driving. The sensor readings are correct.

Tech is a factory tester. No error codes? To check the parameters during operation.

Support replaced with a stimulant (functional from another Corsa).
Works without turning sensor calibration.
