Avensis T22 2.0 16V 128km 3s-fe 2000 - Troubleshooting High RPM and Choke Speed Issues

Hello

My problem is the high speed of the Avensis t22 2.0 16V 128 km 3s-fe 2000 years. For some time, after driving quite longer sections, about 100 km or more, the revs increased to about 1600 at idle, a few times the speed was returned to normal. After starting in the cold after a night on the intake, the revolutions reached 2,000. now the problem has intensified, namely after firing the suction is the same as it was around 2,000, but after heating the engine, the revolutions reach about 1400-1600 rpm. However, when I start after a short stop, e.g. after refueling, it is ok, but after driving even a dozen or so meters and putting it into neutral, the revolutions increase to 1400-1600. I cleaned wd40 this valve from idle speed, but it did not do anything, although it fell out a bit of muck .... The question now is whether you need to replace the entire throttle or only this valve - the electromagnet, the so-called ISC valve, which I do not know if it can be replaced and somehow knock him out.

The diagnostic computer shows something?

The computer shows nothing, after unplugging the plug from the ISC sensor, the check is included and after plugging it in, it disappears.

Take a picture of the presenter

It seems to me that the twki problem in this sensor because when the plug fires after unplugging it, the revs drop and when I unscrew it and I turn it, the engine reacts only after turning it on, it goes up slightly, it probably is something wrong, this sensor

Hello. I had the same. The problem was solved despite the broken lambda probe. I have a 2.0 vvti engine. From the valve cover on the left side, looking from the front of the engine, there is a thick emphysema pipe running to the intake. the air should go both ways, not one way. After blowing and cleaning with penetrating agent, the turnover on the cold dropped from 2000 thousand to 1400.
