Ok. For now i know why i don't get any codes - TPS failure would throw code only for CA specification (got it from service manual).
I used big flat head-blade screw driver and all I got was 1000 RPM not 800RPM.

 

Glina; Is that CA as in California? Interesting, as I am in California.

Anyway, how far did you turn that setting? I had to turn quite a way. Make sure the dashpot on the throttle is allowing a full return (to idle).

If all else fails, then you may have to adjust the fixed screw to the right and back of the dashpot. Wouldn't think that should be the case, but someone could have changed it from the original factory settings.

 

Yes Ca stands for California. I checked dashpot - you were right now it's 800 and it drives very well.

Do I need to connect tps if everything is fine now?

 

Excellent!

You know, after my last note I was reminded of the following....

Don't know if you are old enough to remember Sterling Moss, the great formula 1 driver in the 70's.

Sterling was a nat's behind away from winning LeMan's when his fan belt broke, apparently forcing him to stop.

A breathless reporter runs up and asks Sterling what he would do next year. Sterling answered: "Next year I'll take the bloody thing off...."

I think what that TPS does is merely tell the ECU if the throttle is in the idle position. Why does the ECU care? Because the whack-job california clear-air beaurocracy had a thought. "Hey Guys, we must prevent those fast idle cases out there that might be polluting our air!". "We'll mandate that the throttle return to the full idle position".

Apparently, that is what has happened. And to prevent the confusion of having different designs for every state and every country, Toyota uses a common design, but gives non-California models a break, and doesn't flag a TPS failure with an ECM code.

Go in peace my friend, leave the bloody thing disconnected.

 

Try the catalytic converter.
