What do P2111 and P2112 together mean?
Quick answer
In Ford’s OBD system-operation material, P2111 means “Throttle Actuator ‘A’ Control System – Stuck Open,” and P2112 means “Throttle Actuator ‘A’ Control System – Stuck Closed.” They are distinct monitor codes, not proof that the throttle is stuck now or that a particular part has failed. Vehicle details and applicable service information are needed to interpret the pair. [S1]
The question, the details, the next step.
My scanner shows P2111 and P2112. Do the two codes mean the throttle is stuck both open and closed?
Not necessarily. In Ford’s OBD system-operation material, P2111 is labeled “Throttle Actuator ‘A’ Control System – Stuck Open,” while P2112 is labeled “Throttle Actuator ‘A’ Control System – Stuck Closed.” Those are distinct monitor-code descriptions; seeing both does not establish that the throttle physically occupied both states, or that either condition is happening now. The document also does not establish that a particular component has failed. [S1]
Treat the pair as a clue to investigate, not a parts-shopping instruction. The definitions are Ford-specific material, so first confirm whether they apply to your vehicle. A code reader’s display alone is not enough to determine the cause.
Could one be an old code and the other the current problem? What should I check on the scan report?
That is possible, but the code pair by itself cannot tell you which report is current or historical. The cited Ford document lists the two codes but does not explain how to distinguish current from historical reports for an unspecified vehicle. [S1] Record the exact status shown for each code, if available, and ask the technician how your specific vehicle identifies code status.
Keep any available freeze-frame information with the code it belongs to. Record what the vehicle was doing when the warning or complaint occurred, and whether the complaint is happening now. These details organize the evidence; they do not diagnose the fault.
What vehicle information should I provide, and how do I avoid assuming the throttle body needs replacing?
Give the qualified diagnostic shop the year, make, model, and engine, plus the exact code status and the freeze-frame context for each code if available. Include the symptoms you noticed, when they occur, any recent relevant work, and whether the codes returned after a previous visit. Use placeholders until you have the details; do not guess at a missing engine or status.
Ask the shop to confirm that these definitions and the applicable service information match your exact vehicle before interpreting them. The source is Ford-specific and says the code list is not proof of a currently stuck throttle or a failed part. [S1] It does not establish a cause for your vehicle, a test result, or a repair. Do not force throttle movement based on this code list. [S1]
Can you give me a short note to send with the scan report?
You can copy and fill in this note:
“Please assess P2111 and P2112 on my [year] [make] [model], [engine]. The scanner lists P2111 as [status] and P2112 as [status]. Freeze-frame details: [attach report or write ‘not available’]. Current complaint: [describe what happens and when, or ‘no noticeable complaint’]. Please confirm the code definitions and applicable service information for this vehicle, determine whether each code is current or historical, and explain what evidence supports any proposed repair. I have not forced throttle movement.”
A useful first conversation is about confirming the vehicle-specific information and code status, then explaining what the available records do and do not show. The code pair alone cannot answer those questions.
A practical checklist
Write down the year, make, model, and engine; mark unknown details as unknown.
Record the exact status shown for each code, if available.
Keep available freeze-frame information with the corresponding code.
Describe the current complaint, when it occurs, and whether it is still happening.
Ask the qualified technician to confirm vehicle-specific definitions and explain the evidence before recommending a repair.
Do not force throttle movement based on the code list.
A few more useful answers
Do these codes prove the throttle body has failed?
No. The cited Ford material lists code descriptions, not proof that a particular part has failed. Diagnosis requires vehicle details and applicable service information. [S1]
Does the code pair tell me which code happened first?
No. The cited code definitions do not establish sequence or whether either report is current or historical. Check the available status and freeze-frame records with a qualified technician. [S1]
Can I use the Ford code definitions for any vehicle?
Do not assume so: the cited material is Ford-specific. Confirm the definitions and diagnostic information for the exact year, make, model, and engine. [S1]
