p2110 on 12' jk

I recently was on the highway and heard a chime to see me mph gauges dipped all the way down and back up suddenly only to return to normal operation. When I got to a place I could stop I checked the codes and the jeep has a p2110 code. My mechanic (since I don't trust dealers) checked it and tried everything he could, he says I need a new electronic throttle body. I only have 24k miles on the jeep and I have never received any warning lights. Any ideas to the problem? Could off-roading it have caused water to short the PCM out or anything?

Is your JK running normally now?
What do you mean your mechanic tried everything he could?

Why not take it to the dealer since you are still under warranty?


There is a lot to check before condemning the throttle body.
Here is the info for the code you have:

P2110-ELECTRONIC THROTTLE CONTROL - FORCED LIMITED RPM


Set Condition:
When the PCM requests to limit engine speed if PWM is too high for 20.5 seconds and before P2118 sets. One trip fault and the code will set within 5 seconds. ETC light is illuminated.


Possible Causes

THROTTLE PLATE STUCK

(K124) ETC MOTOR (+) CIRCUIT OPEN

(K126) ETC MOTOR (-) CIRCUIT OPEN

(K124) ETC MOTOR (+) CIRCUIT SHORTED TO GROUND

(K126) ETC MOTOR (-) CIRCUIT SHORTED TO GROUND

ETC MOTOR

POWERTRAIN CONTROL MODULE (PCM)

It is running normal that's what is confusing and by checking everything I mean he went through all possible service solutions other then replacing the throttle body and none of them worked.

sometimes it takes a paragraph...

Ah off road? water? Well normally being off road. Is not a reason for water to damage something.

Now are we talking swamping it? maybe hit a deep puddle at 60mph?

So tell us more about the water...............

never swamped and never hit a puddle going too fast. It seems to be running normal but that might be because the problem progressed slowly and im use to it now. I can buy a new throttle body for 150 so im thinking ill do that so that I have a spare incase this ever goes out randomly on me.

Are you still under warranty? If so, Why on earth would would you not just take it to the dealer? If there is a problem, they can diagnose and fix. If not, why spend money to buy parts just in case without a complete diagnosis?

If you only have 24k miles on it, yes it is.

Then why didn't you mention that in your previous replies to posts that questioned it when you made your backhanded comment about a dealership you can't even go to in the first place?

A salvage title changes a lot of things, even if it's just "cosmetic."

I would unplug every connector. Inspect and clean each one. Then re-connect them. They never put that in trouble code list and it has fixed more than one vehicle I have worked on. Any big impact to the vehicle could make a connection loosen up. I have seen some weird things on brand new vehicles.

I didn't have to mention it because I just needed to state it wasn't under warranty but I guess my own judgment needs questioned. The backhanded comment was because I have dealt with them in the past with nothing but issues and I am able to go to them for everything just without the warranty aspect.
