I changed my spark plugs out and after I reconnected everything I started my car and it instantly started idling rough and threw a P2104 and P2111 code for throttle actuator stuck closed. I’m not sure what to do or if I need to buy another one?

Hi,

I'm sure it's something simple. First, I attached a pic below that shows the possible causes of the P2111. That is the stuck code you indicated. The other code is to indicate the vehicle is in a "fixed idle" mode.

Now the throttle body is on the intake. If you follow the air intake tube from the air filter box, it will lead you to the throttle body (TB). Since this just happened, check the following:

1) Did you disconnect the electrical plug in pic 2 (circled)?

2) Make sure that connector is tight and not damaged.

3) I have an arrow titled TP which stands for throttle plate. Look at the TP and make sure nothing is preventing it from closing.

__________________________________________

Since this happened after the work was done, I suspect a wire is disconnected, pinched, or something is preventing the TP from fully closing.

Let me know what you find.

Joe

Yes, I did disconnect that plug. I made sure it there was no damage done to it and connected it securely. As far as I can see there is nothing in the way from preventing it to open up. So confused just wanted to change my plugs and caused a bigger mess.

Hi,

Allen, did you make sure the plug to the TB is placed and not reversed?

I could be wrong, but I honestly feel it is something easy to fix. That doesn't just go bad from a tune up. I can provide diagnostics but they are extensive and require a live data scanner.

Just for the heck of it, disconnect the battery. With both terminals disconnected, zip tie them together for about 30 minutes. Then, reconnect them. Lets see if a hard reset will do anything. By holding the terminals together, it allows any capacitors to discharge. The vehicle may act a bit strange for a few miles during a relearn, but it should return to normal within a mile or two.

Let me know.

I can check the plug again but I believe it is placed right. I disconnected the negative post and connected the positive to the negative with jumper cables but no reset I will try you’re method but not sure I have zip ties. I also do have a scanner with a live feed as well.

Hi,

It's worth a try. As far a zip ties, anything that will keep them connected will work.

Let me know.

Nope didn’t work. Had a mobile mechanic come look at it and now it’s showing different codes including one for theft system activated. So dealership is coming to get it tomorrow to see if they can fix it.

JACOBANDNPICKOLAS - changed spark plugs on 2015 Santa Fe, started engine and went into limp mode. Pulled DTC P2104. Seen your diagram above, double checked my TB, didn’t connect the connector! Thanks. I would have sworn I hooked everything up right. Didn’t even notice it on the bottom of the throttle body.
