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.
Delphi Announces New SKUs For Fuel, Engine Management And Steering And Suspension In North America
In total, the company has released more than 260 new SKUs.
Steering Angle Frequently Asked Questions
Chances are you will never crack open a steering angle sensor (SAS) cluster to repair it. But, this sensor should not be a mystery. To be effective at ABS and stability control diagnostics, knowing how sensors measure angles and information is critical.
Replacing Wheel Bearing Hubs Equipped With Wheel Speed Sensors
When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside.
Making Sense Of Steering Angle Sensor Input And Data
Measuring the position angle, rate of turn and force of the steering wheel is critical for Electronic Stability Control (ESC) systems. Scan tools call these Steering Angle Sensors (SAS) and typically display the information in degrees.
Steering System Calibrations
We all know that the evolution of technology in our ever-changing automotive industry translates to many gray areas when it comes to servicing new vehicle systems using updated service procedures and tools. Steering angle sensor calibration is one of those gray areas.
Electric Power Steering Diagnostics
Electric power steering is more energy efficient than hydraulic systems and does not provide assist until it receives driver input, but there are differences in the hydraulic and electric assist that will affect the driver’s and technician’s understanding of the component and its integration into the ESC and self-park system.
Electric Power Steering: Past, Present and Future
Electric power steering is fast becoming a standard feature on new vehicles, but it’s not an emerging technology, as it’s been in the field for the better part of two decades. One of the first domestic applications that almost made it to production was the Pontiac Fiero. The 1989 model was going to have an
Electronic Power Steering: A Change In Technology
An Electronic Power Steering (EPS) system’s advantage over a hydraulic system is if the engine stalls, you will still have steering assist. This advantage can also be a disadvantage if the system should shut down while the engine is running because if the engine stalls, you lose steering assist. A driver unaware of this condition
Steering Angle Sensor Diagnostics
Measuring the steering wheel position angle and rate of turn, which are critical for Electronic Stability Control (ESC) systems, is the job of the Steering Angle Sensor (SAS). The scan tool will typically display the information in degrees.
