VIDEO: Can Electric Power Steering Smooth Out Road Crown?
Jason Stahl discusses electric power steering and how it senses driver activity in order to smooth the vehicle’s suspension movements on turns.
VIDEO: Power Steering ECM Technology
Andrew Markel discusses power steering systems, and how it uses sensors and the ECM to add steering assist during certain road conditions.
VIDEO: Power Steering Pump Leak Diagnostics
Andrew Markel discusses the power steering pump, and how to determine if the pump or the rack needs replaced when fluid is visible.
Electronic Power Steering: Better Than Hydraulic?
Diagnosing electric power steering systems requires an understanding of voltage, current and loads. Also, a technician must understand how the modules and sensors work together to determine the level of assist.
VIDEO: Reprogram The Steering Angle Sensor On A Power Steering Job
Andrew Markel explains the easily forgettable step of reprogramming the steering angle sensor after replacing the steering rack and pump.
Power Steering Fluid: To Flush Or Not To Flush?
When a repair is made on a power steering system, there’s a chance that metal shavings can enter the system. This can lead to premature failure of the rack and cause a costly comeback.
VIDEO: When A Power Steering Pump Explodes
If a power steering pump self-destructs, every particle needs to be retrieved from the system to prevent further damage to other components.
Diagnosing Electrical Power Steering (EPS) Issues
Electric steering is a non-hydraulic system assisted by an electric motor operated by a software-driven power steering module.
GM Tech Tip: Grease Or Sealant Visible On Electronic Power Steering Gear Is Not A Leak
On GM vehicles with electric power steering starting in 2009, you may see grease or sealant on certain locations of the steering gear
Power Steering Loss On A 2008 Ford Escape
The 2008 and newer Escape models use electric assist power steering. Instead of a conventional power steering pump, these vehicles have a power steering control module (PSCM) that works along with an electric motor, a torque sensor and various other angle sensors to achieve the desired steering effect.
