2008 HHR Power Steering works only once in a while need help trouble shooting


Electronic power steering . Do you know anything about automotive electronic's ? Electronic power steering control module , sensor inputs an output control ? DTC'S - diagnostic trouble codes . Electrical testing ? Do you have a professional type scan tool to check input an output data , codes ?
Power Steering System Description and Operation (Non-Turbo)
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.
Torque Sensor
The PSCM uses a torque sensor as it's main input for determining the amount of steering assist. The steering column has an input shaft, from the steering wheel to the torque sensor, and an output shaft, from the torque sensor to the steering shaft coupler. The input and output shafts are separated by a torsion bar, where the torque sensor is located. The sensor consists of a compensation coil, detecting coil and 3 detecting rings. These detecting rings have toothed edges that face each other. Detecting ring 1 is fixed to the output shaft, detecting rings 2 and 3 are fixed top the input shaft. The detecting coil is positioned around the toothed edges of detecting rings 1 and 2. As torque is applied to the steering column shaft the alignment of the teeth between detecting rings 1 and 2 changes, which causes the detecting coil signal voltage to change. The PSCM recognizes this change in signal voltage as steering column shaft torque. The compensation coil is used to compensate for changes in electrical circuit impedance due to circuit temperature changes from the electrical current and voltage levels as well as ambient temperatures for accurate torque detection.
EPS Motor
The EPS motor is a 12-volt brushed DC reversible motor with a 61-amp rating. The motor assists steering through a worm shaft and reduction gear located in the steering column housing.
Power Steering Control Module (PSCM)
The PSCM uses a combination of torque sensor inputs, vehicle speed, calculated system temperature and the steering calibration to determine the amount of steering assist. When the steering wheel is turned, the PSCM uses signal voltage from the torque sensor to detect the amount of torque being applied to the steering column shaft and the amount of current to command to the EPS motor. The PSCM receives serial data from the engine control module (ECM) to determine vehicle speed. At low speeds more assist is provided for easy turning during parking maneuvers. At high speeds, less assist is provided for improved road feel and directional stability. The PSCM nor the EPS motor are designed to handle 61 amps continuously. The PSCM will go into overload protection mode to avoid system thermal damage. In this mode the PSCM will limit the amount of current commanded to the EPS motor which reduces steering assist levels. The PSCM also chooses which steering calibration to use when the ignition is turned ON, based on the production map number stored in the BCM. The PSCM contains all 8 of the steering calibrations which are different in relation to the vehicles RPO's. The PSCM has the ability to detect malfunctions within the EPS system. Any malfunction detected will cause the IPC message center to display PWR STR (or Power Steering) warning message.

I30 2016 model.Bought December steering is stiff - sticky above 60 mph making small direction changes difficult to acheive. It is fine at lower speeds


take it back in for a steering module check
the hyundai I 30 elantra has a recall ( 2015) for loss of power steering due to a loss of steering assistance from an electrical power steering fault
There is a control module that applies full assistance at low speeds , parking or cornering but reduces the assistance effort at speeds where assistance is not really required
from your description, it indicates that the control module is not functioning correctly and so you are advised to take it back in for a recall check or a warranty check on the system

Where is the power steering pump located?


ELECTRIC POWER STEERING (EPS)
The TSX uses Electric Power Steering (EPS) which regulates steering via a computer-actuated electric motor. With the computer-controlled system, advanced algorithms built into the operating software allow for continuous fine-tuning of the steering assist forces so that minimal force is required at low speeds- such as when parking or maneuvering. Conversely, progressively higher steering effort is generated at higher speeds (such as when driving on the freeway) to deliver a sport-minded driving experience.
The EPS system found in the TSX is an evolution of an earlier EPS system found on the Acura NSX supercar. Its key features and advantages include:
  • The EPS system reduces the steering effort at low speeds, improving agility and ease of effort when parking or maneuvering in tight areas
  • Rigidity of the steering mount is higher, which allows a more precise and "connected" feel during high-speed maneuvers (such as during lane changes or when on winding mountain roads)
  • The EPS steering assist incorporates computer algorithms based on vehicle speed rather than engine speed, allowing TSX engineers the flexibility of tailoring the steering feel to match actual driving conditions- especially high-speed driving. The EPS steering algorithms incorporate steering assist changes for every 0.6 mph.
  • The EPS system is different (and uniquely tuned) for each of the TSX models: 2.4L I-4 sedan, 3.5L V-6 sedan, and the new Sport Wagon.
  • EPS employs a sporty, 13.5:1 steering ratio which further improves performance driving agility
  • In its evolution from the original NSX system, the TSX's EPS system uses a significantly more powerful electric motor teamed with a far more sophisticated microprocessor
  • By eliminating the conventional power steering pump assembly, EPS uses less engine power which improves acceleration and fuel efficiency
it is an electric pump without a pulley or belt or fluid apparently

Steering light came on a 2006 jetta 5


Hmm, Your vehicle does not have a typical hydraulic power steering system, instead it has a electric actuator that assists the steering.

Get your vehicle (VAG-COM) scan for codes and post the VW fault codes or do a forum search once you have the fault codes.


You may possibly see the following codes:
  • 01309 - Power Steering Control Module (J500)
  • 004 - No Signal/Communication - Intermittent

The steering light will be only two colors, yellow or red (in your case yellow):

Yellow means there is an issue with the system and it will run at reduced voltage when it can but you will still have assist.


Red means there is a serious issue were the system can not give you assist and you should not attempt to drive it like this.


The yellow light can be cause by many things, but most common is a low battery. When the battery voltage drops below 11.7v or so, the system stores a DTC and illuminates the icon to inform you there is an issue with the system and it may work at reduced assist. Since this system is so heavily dependent on a good charging system and battery.



Again I suggest drop by your local dealer and have them scan the Steering Module to see why the light is on.

Why has my SSPS light turned on..what is the problem and how to solve it?


SPSS or Speed Sensitive Power Steering warning light.
Not something you can fix unless you know how to pull a steering column out and have a scan tool to reset the light once the sensor is replaced. The sensor itself is expensive ( over $200 )

You might have something wrong with your power steering. Could mean low power steering fluid if you haven't check it lately. Bad sensor like what happen to my car or things wrong with your power steering pump,control arms

The only thing that happens with a bad sensor is that you have full time power assist.
Speed Sensitive Steering reduces the amount of power assist at hwy speeds so as to give the driver better "road feel".

Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer. Thank you for using FixYa.

The steering in my 98 Buick Century is hard to turn at low speeds. Is this a steering pump issue or the rack and pinion?


Your PS pump is fine.

This vehicle has:

Variable-assist power steering: A power steering system that uses valves and speed sensors to vary the amount of steering assist according to engine or road speed. At slow speeds more steering assist is delivered and steering the wheels is easier; necessary for parking, etc.. At higher speeds, steering assist is reduced and more steering effort is required to steer the car, giving the driver greater feel of the road. Also known as Speed-sensitive power steering.

Loss of current to the magnetic coils would cause a loss of power assist at low speed. Coil resistance can be checked with an ohmmeter, and should read about two ohms. An infinite (open) reading indicates a bad coil (requires replacing the rack since the coils are not serviceable). Checking for shorts between both sides of the coil assembly and rack housing is also recommended.

Best wishes

Recently I'm having trouble steering.


These are very good cars and very simple steering systems. The power steering pump needs to be inspected. They use bushings to aide in holding these inplace. If there is an oil leak, the bushings become soft and will not allow the belt to remain tight thus causing a slip and reduce power function. Let me know what you find and if you need further assistance.

Power steering failure


Problems with electronic variable-assist systems include all of the same things that can go wrong with a conventional power steering system (leaks, center wear in the steering gears, pump & hose failures, etc.), plus problems with the control electronics including the vehicle speed sensor circuit, the solenoid valve and control module. Accurate diagnosis, therefore, is essential to minimize warranty returns. Most of these systems provide diagnostic fault codes that can be accessed with a voltmeter, test light or scan tool to pinpoint the nature of the fault (if the fault is electronic rather than mechanical or hydraulic).

If power to the solenoid or control valve actuator is lost, the valve keeps the bypass circuit closed so full power assist is provided under all driving conditions. The only indication of trouble, therefore, might be a loss of road feel and/or increased steering sensitivity at highway speeds.

It’s important to remember that variable-rate power steering only reduces the amount of pressure that reaches the steering gear at higher road speeds. The only way it could reduce power assist at low speed would be in the unlikely event the actuator or solenoid valve failed in the open position. This could cause a noticeable reduction or loss of power assist.

On GM’s Magnasteer racks, loss of current to the magnetic coils would cause a loss of power assist at low speed. Coil resistance can be checked with an ohmmeter, and should read about two ohms. An infinite (open) reading indicates a bad coil (requires replacing the rack since the coils are not serviceable). Checking for shorts between both sides of the coil assembly and rack housing is also recommended.

The system does have self-diagnostic capability, but there is only one fault code: C1241 (Magnasteer circuit malfunction). The code is set if the module detects an open or a short in the coil circuit. If this code is present, the Magnasteer system is disabled and will not vary the steering effort as vehicle speed changes. The C1241 body code can be read with a Tech 2 or equivalent scan tool. The Tech 2 tool can also be used to perform a Magnasteer function test. The test varies the current to the coil so you can check for a change in steering effort when turning the steering wheel.

Replacement racks for variable-assist power steering applications are available with or without an EVO control solenoid. As long as the original EVO control solenoid is working OK, it can be removed and installed on the replacement rack to save your customer a few bucks. There’s no need to replace the whole rack if only the EVO solenoid valve is defective.

On GM Magnasteer applications, the whole rack must be replaced if the rack or control unit is defective because the Magnasteer unit is part of the rack. Handle with care because the permanent magnets inside the Magnasteer valve assembly and connector are fragile and can be easily damaged.

Good luck and hope this helps you understand the Steering system on your STS to save you some money on what to look for and what to look out for if your going to have a auto shop repair it. Such as the Valve is replaceable and it may just be a bad wire connection.
