This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the throttle on one side of the engine is not opening and closing as smoothly as it should. Imagine if a door was hard to open and close; that's similar to what's happening here.
The engine control module (ECM) has detected that the throttle body on bank 2 is not operating smoothly. This could be due to mechanical resistance or electronic issues.
The P11AB code is triggered when the ECM detects an abnormal resistance or tightness in the throttle body operation on bank 2. This could be due to mechanical binding, a malfunctioning throttle actuator, or electrical issues affecting the throttle position sensor.
• Reduced engine performance
• Check Engine Light illumination
• Poor throttle response
• Engine stalling or hesitation
• Mechanical binding in the throttle body
• Faulty throttle actuator
• Issues with the throttle position sensor
• Wiring problems in the throttle control circuit
• Carbon buildup in the throttle body
Throttle Body: A component of the air intake system that controls the amount of air flowing into the engine.
Throttle Actuator: An electronic device that controls the throttle body's movement.
• Perform a visual inspection of the throttle body and linkage.
• Check for any diagnostic trouble codes related to the throttle system.
• Test the throttle position sensor and actuator for proper operation.
• Inspect the wiring and connectors for damage or corrosion.
• Clean the throttle body to remove carbon buildup.
• Replace the throttle actuator if faulty.
• Repair or replace damaged wiring or connectors.
• Replace the throttle position sensor if necessary.
• OBD-II scanner
• Multimeter
• Throttle body cleaner
• Basic hand tools

Moderate
• Toyota Camry
• Ford F-150
• Chevrolet Silverado
• Regularly clean the throttle body.
• Ensure proper maintenance of throttle linkages.
• Inspect and replace air filters as needed.
Engine Performance
• Avoid driving aggressively until the issue is resolved.
• Have the vehicle inspected by a professional mechanic.
• Monitor engine performance for any worsening symptoms.
Throttle body and related components may be covered under the vehicle's powertrain warranty.
The P11AB code has been reported in various vehicles, often related to mechanical binding or electronic issues in the throttle system.
Moderate – While the vehicle may still be drivable, it is important to address this issue to prevent further engine performance problems.
Driving with a malfunctioning throttle system can lead to reduced vehicle performance and may pose a safety risk.
• Engine at operating temperature
• Vehicle in park or neutral
The throttle body is located on the intake manifold, typically near the air filter housing.
Q: Can I drive with a P11AB code?
A: While you may be able to drive, it's not recommended as it can affect engine performance and safety.
Q: How do I clear a P11AB code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is resolved first.

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.
