This summary uses the existing diagnostic information shown in full below.
The car's computer thinks the air going into the engine is too hot on one side of the engine.
The P11B5 code indicates that the intake air temperature sensor 2 on bank 2 is reading a temperature that is higher than expected.
The intake air temperature sensor measures the temperature of the air entering the engine. Bank 2 refers to the side of the engine opposite bank 1, usually in a V-type engine. A high reading could indicate a sensor issue, wiring problem, or an actual increase in intake air temperature.
• Check Engine Light is on
• Poor engine performance
• Decreased fuel efficiency
• Faulty intake air temperature sensor
• Wiring issues or poor connections
• Actual high intake air temperature due to engine conditions
OBD-II: On-Board Diagnostics, a standardized system for vehicle self-diagnostics.
Bank 2: The side of the engine opposite bank 1, usually in a V-type engine.
• Use an OBD-II scanner to verify the code.
• Inspect the intake air temperature sensor and its wiring on bank 2.
• Check for any air leaks or blockages in the intake system.
• Replace the intake air temperature sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Ensure the intake system is free of leaks and blockages.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Ford F-150
• Chevrolet Silverado
• Regularly inspect and clean intake components.
• Ensure proper maintenance of sensors and wiring.
• Avoid driving in extreme conditions without necessary precautions.
Sensor Issue
• Do not ignore the Check Engine Light.
• Consult a professional mechanic if unsure about the repair process.
Check with the vehicle manufacturer for warranty coverage on sensors.
This code is relatively common in vehicles with intake air temperature sensors that are prone to failure or wiring issues.
Moderate – Should be addressed to prevent further engine performance issues.
Continuing to drive with this code can lead to increased emissions and potential engine damage.
• Engine at operating temperature
• Vehicle in a controlled environment
The intake air temperature sensor is located in the intake manifold on bank 2 of the engine.
Q: Can I drive with a P11B5 code?
A: It's not recommended as it can lead to further engine issues and decreased performance.
Q: How can I reset the Check Engine Light?
A: After fixing the issue, use an OBD-II scanner to clear the code.
