Power Steering Pressure Sensor
Tells the engine module that the steering is loaded, so it can raise idle to absorb the load — hydraulic steering at full lock takes enough power to stall an engine at idle. The consequence of losing the signal is therefore not a steering complaint at all but an idle that dips or stalls when parking, which is why the code and the symptom seem unrelated.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
