Can you tell me what type of vehicle you are driving? With the number of vehicles out on the market, there's really no way to give a generic answer.

2005 Hyundai xg350 showing code p2112 changed tps and idle control valve still acting the same still showing same code


On chevys after you fix the problem you have to disconnect the battery for a minute then reconnect it. That resets the computer and it does new search for what's wrong and if fixed doesn't find anything. Might try that.

I have 3 codes from my scaner p2111 p2112 p2238


P2111 - Throttle Actuator Control System Stuck Open.
P2112 - Throttle Actuator Control System Stuck Closed.
P2238 - O2 Sensor Positive Current Control Circuit Low Bank 1 Sensor 1



For the P2111 & P2112 you will need to replace the throttle body this can be pricey since the TAC is built into it. Try cleaning it good and see what happens. This can also trigger the P2238 code if its dumping fuel.
For the P2238 check the connections on the o2 sensor or replace the upstream o2 sensor that should correct it.

2005 Ford Expedition (4wd) with trouble codes p2104 and p2112 completely cuts off at low speeds. All signs point to throttle position sensor, but want to make sure I'm on the right track.


Shown here is the P2104 obd2 code and their general meaning. For a brief description of any particular OBD2 code and how to fix the obd2 trouble code, please browsw below. P2104 Engine TP Actuator Cntl System
This obd2 code is very common on newer vehicles which contain new design of throttle positioner sensor. Instead of putting a tps sensor at the side of your throttle body as in older engines, a throttle actuator control system is installed which eliminates the mechanical linkage (cable) between the throttle body and the throttle pedal. Under the throttle pedal, a throttle switch is installed and a throttle module or actuator is incorporated beside the throttle body. Because there is no mechanical device that wears out, it is more effecient in delivering better mileage and performance torque (besides...the actuator module performs better in getting all throttle signals to the ecm and trany).
To test this code, check the integrity of the wires going to both the throttle body actuator and the ecm including the throttle switch. Most of the time, if you have symptoms like trany going to a limp mode, the culprit originates from the trany circuit. However, if the symptom is engine related like hesitation, the problem resides in the throttle actuator itself which may sometimes includes the replacement of the whole throttle body assembly. Contact ATS if you need a wiring diagram or detailed fixes for your throttle actuator control system.
TIP:
Before replacing the throttle control actuator and throttle body, try cleaning the throttle plates and all plug-in wiring connections. Also, watch out the throttle body mounting bolts which can easily break (use care) when removing them.
