Problem for my suzuki solio is when its run long the esp and check engine is on the engine will not start or its hard to start can you help me me what is the real problem?

no defeats purpose of stat and will cause problems since their will be a constant flow and most likely gasket will not seal causing leak

Here's a link to your P2102 code. P2102 Throttle Actuator Control Motor Circuit Low

any power steering (belt direct or electrical driven ) that is hard to steer indicates a fault in the pump. In this case check the power circuit and then pump controls. Take it to a accredited steering specialist shop and check the fluid level as well.

I suspect the belt is lose. Its probably not turning water pump or the power steering pump. You car has an electric cooling fan, but it still won't cool if the pump isn't circulating the water through the radiator. Should be easy to tell. Just look under the hood with the engine running and have someone turn the wheel. You should be able to see, hear and or smell if the belt is slipping

clean clear , anon, double post, and still no car named,
nor real engine.

one of these?, sorry cant guess that or the engines.... ever.-

take to a audi garage befor you do some expensive damage

what country? what year car.?
all engines stall for only 4 reasons. (the tests are many)
1: lost 12vdc POWER to EFI. (if EFI)
2: lost compression hot, 150psi is min.WOT.
3: lost park.
4: bad fueling. (too much or too little)

do you want to guess?. or buy tools and do the simple tests.
it's your choice, always.
we dont need your name but the country, now that be SPIFFY.

the esp stands for electronic stability program,you will need to have the computer scanned for codes, these codes will help in the repair,you may have a bad speed sensor or the check engine light may have shut down the esp,when the engine detects a problem it shuts down the esp because it feels that the esp cant operate correctly when the engine is not running correctly,so the first thing is to scan for the codes, hope this helps, good luck,

The problem is that the ESP system is not active.
The ESP lamp normally is on for a few seconds after strating the engine - but must dissapear after a couple of seconds.

The failure is not critical but has to be repaired. Normally the failure is related to a defective ESP-controle box.
Be prepared - repair is expensive !!!!

this solution is not specific, but their is at least 1 manufacturr recall to correct the wiring for the ESP.
also their is some Firmware upgrade available for the engine computer at your Suzuki Dealer.
Finally my Dealler corrected a problem with an underneat wire connector hos strated to corrode. I had exactlythe same symptom described along with occasinnal errtic hidle engine speed.
