This summary uses the existing diagnostic information shown in full below.
The car's computer is confused because the two sensors that tell it how much you are pressing the gas pedal aren't agreeing with each other.
The throttle position sensors (TPS) A and B on Bank 2 are not showing expected readings. This means the signals from these sensors are not within the expected range or don't match each other.
The P11BD code indicates a discrepancy between the readings of Throttle Position Sensor A and Throttle Position Sensor B on Bank 2. The Engine Control Module (ECM) expects these sensors to provide consistent and matching data about the throttle position. If the readings are outside the expected range or don't align, the ECM triggers this code.
• Check Engine Light is on
• Poor engine performance
• Hesitation or stalling
• Faulty throttle position sensor
• Wiring issues or poor connections
• Failed ECM or PCM
Throttle Position Sensor (TPS): A sensor that monitors the position of the throttle in an internal combustion engine.
ECM: Engine Control Module, the computer that controls engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the throttle position sensors with a multimeter.
• Replace faulty throttle position sensor.
• Repair or replace damaged wiring.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and clean throttle body.
• Ensure wiring is not exposed to excessive heat.
• Perform routine maintenance checks.
Sensor Issue
• Avoid driving at high speeds until fixed.
• Get the vehicle inspected by a professional mechanic.
• Do not ignore the Check Engine Light.
Check if your vehicle's warranty covers sensor or ECM issues.
This code has been commonly reported in vehicles with high mileage or those that have not had regular maintenance.
Moderate – It should be addressed soon to prevent further engine performance issues.
Driving with a malfunctioning throttle position sensor can lead to unsafe driving conditions.
• Engine at operating temperature
• Vehicle in idle and under load
The throttle position sensors are located on the throttle body, which is typically found on the intake manifold.
Q: Can I drive with a P11BD code?
A: It's not recommended as it can lead to poor engine performance and unsafe driving conditions.
Q: How do I clear a P11BD code?
A: After fixing the issue, you can clear the code with an OBD-II scanner.
