This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is not getting enough power from the part that tells it how much you're pressing the gas pedal. It's like when a toy with low batteries doesn't work right.
The throttle position sensor or pedal position sensor is not receiving enough voltage, which can affect how the engine responds to the gas pedal.
The P11A2 code indicates that the Engine Control Module (ECM) has detected a low voltage condition in the supply circuit for the throttle or pedal position sensor on Bank 1. This could affect the sensor's ability to accurately relay the position of the throttle or pedal to the ECM.
• Check Engine Light is on
• Reduced engine performance
• Unresponsive throttle
• Poor fuel economy
• Faulty throttle/pedal position sensor
• Wiring issues such as shorts or open circuits
• Poor electrical connections
• Faulty ECM
Throttle: A device controlling the flow of fuel or power to an engine.
ECM: Engine Control Module, the computer that manages engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the sensor's voltage supply with a multimeter.
• Check the ECM for any faults.
• Repair or replace damaged wiring or connectors.
• Replace the throttle/pedal position sensor if faulty.
• Repair or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect wiring and connectors.
• Ensure sensors are clean and functional.
• Perform routine vehicle maintenance.
Sensor Issue
• Do not ignore the Check Engine Light.
• Avoid aggressive driving until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on sensors and ECM.
This code has been associated with throttle response issues in various models, often due to wiring problems.
Moderate – It should be addressed soon to prevent potential drivability issues.
Driving with this issue may lead to reduced vehicle performance and safety risks.
• Engine running
• Throttle pedal operation
The throttle/pedal position sensor is typically located near the throttle body or pedal assembly.
Q: Can I drive with a P11A2 code?
A: It's possible, but not recommended as it may lead to poor performance and fuel economy.
Q: How do I clear a P11A2 code?
A: After repairs, use an OBD-II scanner to clear the code.
