Electric Power Steering Sensors
Let’s take a closer look at the sensors which make up EPS systems, and how they operate.
Understanding Steering Sensors
Modern vehicles need to know the difference between what the driver “wants” and what the vehicle is actually “doing.” The vehicle uses sensors that measure steering angle, brake pedal position and throttle angle to know where the driver wants the vehicle to go.

Andrew Markel relates a story from a technician where a jumpstarted car had a miscalibrated steering angle sensor.
Keeping on Track with Steering Position Sensors
Cars just keep getting smarter all the time. Sensors are being used to monitor more and more functions, and to share information between vehicle systems that formerly were mute or didn’t communicate with one another. One such sensor is the steering position sensor. The sensor’s basic function is to monitor the driver’s steering inputs. This
Steering Position Sensors: Keeping on Track
The steering position sensor’s basic function is to monitor the driver’s steering inputs. This includes the angle of the steering wheel and/or the rate at which the driver is turning the wheel. The information may be used to vary hydraulic pressure in a variable-assist power steering system, or by a stability control system to improve
Electric Power Steering Diagnostics
Load management for steering systems.
Ride Height Sensors
If one of these sensors is replaced, it must be calibrated after it is installed.
Steering Angle Sensor Service
Ninety percent of the time when a steering angle sensor code is active, it means the sensor needs to be calibrated.
Hydraulic Power Steering Service Opportunities
Hydraulic power steering is still the choice for some platforms and applications.
