Trafic power steering vibration

My 2013 Renault Trafic gasoline has a power steering issue at 193226 km. The steering wheel vibrates violently, handling is spongy, and steering effort has increased. There's also a stored error code. Could a defective cable or plug connection be the cause?

A defective cable or plug connection is possible. However, vibration and spongy handling could also indicate other problems. Has the wheel alignment been checked? Electric steering systems can be sensitive to alignment. A failing steering pump is less likely on a 2013 model with electric power steering, but it's not impossible. Have you inspected the wiring harness and connectors for corrosion or damage to confirm the connection?

Can you tell me the specific location I should inspect to diagnose this issue effectively? Where can the wiring harness/connectors be found?

The wiring harness and connectors for the power steering system are typically near the steering rack and the electric power steering motor. Given the complexity, it's best to have a qualified mechanic diagnose it. A proper diagnostic scan and visual inspection are essential before repairs. It sounds like the power steering may have failed.

I consulted a workshop, and a defective plug connection was found. The repair cost 95€.
