Engine swicthes of by itself and power steering doesnt work.

Electronic Power Steering (EPS) Is an electronic system not hydraulic like older cars it's supposed to be better because u can still steer even if vehicle stalls unlike hydraulic systems the engine had to be running but if it detects an issue like a bad wheel sensor it will be disabled and making it hard to steer you may need to replace motor on steering column

More than likely the steering column which contains the electric power steering parts, you would need to have it checked with a diagnostic scanner to confirm fault

Bad computer it sounds like, possibly just a bad ground wire

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

check all fuse in both fuse boxes.
power sensor?
electronic power steering failure.
you can:
1: get it fixed. (any ASE shop would be happy to help.)
2: read the FSM and learn the tests to find the cause.
3: and scan the PCM to see what EPS failures are happening,
and post those.
or look them up in the FSM to see the tests.

This can be the gauge but most likely it is the fuel level sender inside the fuel tank that is causing the problem.

vauxhall charge 47 pound to look at the car for you sounds like the steering rack but i cant be sure, i would take it to vauxhall cause a backstreet could get it wrong and it would cost you more

I have a 2006 Accent and also to me sometimes the eps light turn on while I'm driving. I turn off the car and wait few seconds before to turn on again. But how to repair this problem?

My EPS on my mitsubishi colt 2006 stopped working about 8 months now, I changed the electronic box,but it started to work for ten minutes and then stopped.I carried it by some electricians and they put the computer on it, but it is not getting through.Could someone lend some assistance!!!!!!!!!!!!!!!!!!!!!!!!1
