Diagnosis & Testing; Loose Steering / Vehicle Leads / Drifts Troubleshooting Chart - Chery A1 2009 Service Manual

Vehicle Inspection
There is some noise in all power steering systems. One of the most common is a hissing sound. Hiss is a high
frequency noise similar to that of a water tap being closed slowly. The noise is present in all valves that have a high
velocity fluid passing through an orifice. There is no relationship between this noise and steering performance. The
hissing sound is commonly heard during the following operations:
• Evident at a standstill
• At park with the engine running
• When the steering wheel is at the end of its travel
