How To Tell If You Have Variable Assist Power Steering?

The technical advances in the automobile sector make cars easier to operate these days. There is constantly a new feature for improving driving skills. The variable Power Steering Assist is one such feature. Variable power steering aid is a device that depends on the speed of the vehicle.

For example, the car requires less assistance and less control while the speed is increasing using a ford variable-assist steering. With power steering with variable assistance, the aid at low speeds is enhanced and aid at higher speeds lessened. The power steering with Variable Assist allows drivers effortlessly. Learn how to tell if you have variable assist power steering.

How Variable Assist Power Steering Works?

Before learning how to tell if you have variable assist power steering, it is beneficial to know about the system. For these systems, there are various designs and names. The pressure to the steering gear or rack is usually checked and varied. The speed sensors for the vehicle and the rotation sensors for the steering wheel transmit the required signals to the control unit.

Some cars feature a specific unit while others include it in the traction and braking control units. The control device limits fluid flow to the steering gear system when vehicle speed increases. This decreases the chances of drivers exceeding a perceived threat on the roads and improves the stability of the vehicle.

How To Tell If You Have Variable Assist Power Steering?

If you’ve got variable power steering, it can be a very difficult operation for the inexperienced. Some may possibly have wondered “what is magnetic variable aid guidance.” here are some ways through which you can identify variable power assist steering systems-

1. Check Vehicle Specifications

VIN’s identification of vehicle data is as easy as the collection and connection of a Vin number to the VIN decoder. Some VIN decoding services, mainly for commercial usage, permit customers to enter the whole 17-digit VIN pattern (characters 1 through 8, 10, and 11). This functionality is useful for companies that may not always have complete VINs.

Be aware that not every specification applies to each manufacture and model, as certain car manufacturers enable greater personalization than others. In addition, it depends on the data source the amount of information to be retrieved via VIN. As mentioned, the majority can be identified with a commercial VIN decoding system.

2. Presence Of Steering Mode Selector

The cars with this system have many types of driving modes and must adjust them to road conditions. Some drivers enjoy a sporty drive, others want to drive with comfort. The latest automobiles are able to deliver a variety of outputs on demand. These cars provide driving modes that allow the driver to vary the driving nature of the car.

To suit a drive you want, you can tailor. This driving mode can be adapted to your driving style. However, the combinations contain some constraints to make driving safe and effective.

3. Variable Steering Feel While Driving

But, when EPAS systems were developed and polished, manufacturers like Porsche have succeeded in creating electronic systems which match the feel of the hydraulic system and are then in many fields exceeding the mechanical technique. This has been accomplished by changing the direction of the feedback loop within the electronics system.

Many producers are using a system that supplies a steering support force based on a torque sensor calculated from the wheels while Porsche is using yaw sensors, steering angles, and other stability control values to increase and decrease support accordingly and at a much more frequent rate.

4. Lack Of Hydraulic Pump

This is the most common sign about knowing how to tell if you have variable assist power steering. The most advanced technical cross we carry is electrically assisted power steering (EPS). When it originally came up, it seemed a logical notion to replace hydraulic aid with a computer-controlled electric motor.

Every car control will be by-wire someday; today’s EPS looks a step forward. However, we have seen the lack of feeling, badly tuned, and sometimes only odd compared to hydraulic support systems which have profited from more than half a century of growth in the previous decade when driving EPS-equipped automobiles.

Advantages Of Variable Assist Power Steering

The driving pump, tubes, hydraulic fluid, and a driving belt and pulley on the machine are eliminated. As a result, energy-saving and environmentally compatible electrical power steering offer further solutions such as easier tuning, flexibility in packaging, and engine-off steering.

In general, the steering systems react faster than the manual box to the steering input. The lack of support in the manual box means that the equipment must be lower so that the driver can turn the wheel. However, the manual direction is more precise, as more steering input is needed to move the wheels.

What Are The Common Problems Of Variable Assist Steering?

Problem with the variable aid system is all the same as conventional steering systems (leaks, wear at the center of the steering gears, faulty pumps, and shaft, etc.), as well as problems with the control electronics including the vehicle speed control circuit, the solenoid valve, and the steering unit.

Therefore, accurate diagnosis is crucial in order to reduce returns and/or returns. Most of the systems feature a voltmeter, test light, or a scan tool to indicate the nature of the malfunction. The diagnostic failure codes help to fix the problem.

Hydraulic VS Electronic Power Steering

No hydraulic pumps or pistons are present in cars using EPS systems. They are however provided with a simpler electric motor to increase driver controls. This procedure lowers the vehicle’s weight. In addition, like with hydraulic systems, the EPS system does not consume engine power.

The electric steering system is often more efficient. Some believe that a better feel for the road is the hydraulic system and that the EPS system tends to make the driving experience a bit sluggish. Because these views are subjective, you should take the wheel of an EPS and try it out yourself.


While learning about how to tell if you have variable assist power steering, you get to know about the whole system. They are the future of the automotive industry and are closely matching the feel of conventional hydraulic steering. If you still have any questions, then comment down below.
