Engine idle problems

[Mikey_VKG]

I'm having problems running my nb. It starts up but the idle is all over the place. It revs up but I can tell there is something wrong. I have a V-checker Pro I got from ECS tuning. I checked the codes. I have three...

17967.P1559 Throttle valve control part- J388: fault in basic settings

17972.P1564 Throttle valve control part- J388: Insufficient voltage during basic setting

17579.P1171 Angle sender 2 for throttle valve drive- G188: Impossible signal

I've searched for a little bit online, but I'm not sure exactly the problem would be with all three codes.

Thanks,

Check your throttle body/control module on the intake manifold.

I checked and I wasn't sure what to check, all the connections were tight. Not sure what else to check.

Thanks,

Did you take the breather hose off and look down the tube at the throttle body sensor behind the valve flipper? The throttle body also attaches to the intake manifold, the gasket could be bad.

Of course your throttle body could just be bad and needs to be replaced.

It works!! I pulled the senser out in your picture. It was real nasty, so before I bought a new one I tried to clean it. And now it works perfect. I'm going to buy a new one anyway.

Thank you Very, Very much. I suppose the temp sensor was throwing everything else out of whack.

Thank you again!
