Silverado engine stalls at idle

I own a 2023 Chevrolet Silverado with a gasoline engine. Recently, the check engine light illuminated, and the engine stalls at idle. I have also noticed reduced engine power. The vehicle has 160401 km. Could the rail pressure sensor signal be faulty?

Summary of the thread

A 2023 Chevrolet Silverado owner reports the engine stalling at idle, a check engine light, and reduced power. The issue may be linked to a faulty rail pressure sensor signal, as indicated by a diagnostic scan. Another individual with similar symptoms confirmed that a defective pressure sensor was the cause and recommended visiting a workshop for repair.

I encountered similar symptoms with my Silverado. A faulty pressure sensor can indeed cause these issues. Have you scanned the vehicle for any error codes? If so, what codes were reported?

Yes, I scanned it. It indicates a problem with the rail pressure sensor signal. Is this what you experienced as well?

That's correct. The error code pointed directly to the pressure sensor. Considering the symptoms and the diagnostic code, it's highly probable that the pressure sensor is defective. I suggest taking it to a trusted workshop for confirmation and repair. The repair cost me around 240€.

Thank you for the information. I will schedule an appointment with a workshop to have the pressure sensor checked and replaced.
