This summary uses the existing diagnostic information shown in full below.
The car's gas pedal isn't working right because the part that controls how much air goes into the engine is stuck closed.
The throttle actuator controls the throttle valve, which regulates the amount of air entering the engine. If it's stuck closed, the engine can't get enough air to run properly.
The P2112 code indicates that the throttle actuator control system has detected that the throttle plate is stuck in the closed position. This is usually due to a malfunction in the electronic throttle control system, which can be caused by electrical or mechanical issues.
• Reduced engine performance
• Engine may not start
• Check Engine Light illuminated
• Faulty throttle body
• Wiring issues in the throttle actuator circuit
• Failed throttle actuator motor
Throttle Actuator: A motorized device that controls the throttle valve in an engine.
Throttle Body: A component of the air intake system that controls the amount of air flowing into the engine.
• Use an OBD-II scanner to confirm the code.
• Inspect the throttle body and actuator for blockages or damage.
• Check the wiring and connections for the throttle actuator.
• Clean the throttle body to remove any obstructions.
• Repair or replace damaged wiring or connectors.
• Replace the throttle actuator if it is faulty.
• OBD-II scanner
• Multimeter
• Throttle body cleaner

Moderate
• Ford F-150
• Toyota Camry
• Honda Accord
• Regularly clean the throttle body.
• Perform routine maintenance checks.
• Ensure electrical connections are secure.
Engine Performance
• Do not drive the vehicle until the issue is resolved.
• Seek professional diagnostic and repair services.
Check your vehicle's warranty coverage for powertrain components.
This code has become more common with the advent of electronic throttle control systems.
High – This issue can lead to poor engine performance or prevent the vehicle from starting.
Driving with this code may lead to unsafe driving conditions. It is recommended to address the issue immediately.
• Engine at operating temperature
• Vehicle in park or neutral
The throttle actuator is located on the throttle body, which is typically found between the air intake and the intake manifold.
Q: Can I drive my car with a P2112 code?
A: It's not recommended to drive with this code as it can lead to unsafe driving conditions.
Q: How serious is a P2112 code?
A: It's a serious issue that affects engine performance and should be addressed promptly.

Fitment Required · Vehicle-fitment part
Relevant for airflow, fuel-trim, and intake-metering faults after confirming the sensor is actually at fault.
Airflow and fuel-trim codes can involve the mass air flow sensor after proper diagnosis.
Verify the sensor design and fitment for your exact vehicle.
