Power Steering Pressure (PSP) Test

WARNING: This page is about a different variant/trim than selected.

The PSP test checks the ability of the EEC system to detect a change in the power steering system fluid pressure. The steering wheel is briefly turned at least 1/4 of a revolution on vehicles equipped with a PSP switch or sensor. This is done during a KOER on demand self-test.
