This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the throttle on one side of the engine, and it's making sure you can still drive the car slowly to get it fixed.
The engine control module (ECM) has detected an issue with the throttle valve on Bank 2, causing the system to enter 'limp home mode' to prevent damage.
The throttle valve is responsible for controlling the amount of air entering the engine. If the ECM detects a malfunction in the throttle valve on Bank 2, it activates a fail-safe mode called 'limp home mode' to limit engine power and prevent potential damage.
• Reduced engine power
• Check engine light on
• Poor acceleration
• Faulty throttle body
• Wiring issues or poor connections
• Defective throttle position sensor
Throttle Body: A component that controls the amount of air entering the engine.

• Check for any other related codes.
• Inspect the throttle body and its connections.
• Test the throttle position sensor.
• Replace or repair the throttle body.
• Fix any wiring issues or poor connections.
• Replace the throttle position sensor if faulty.

Engine Performance
• Drive carefully to a service center.
• Avoid high speeds until repaired.
Throttle-related repairs may be covered under powertrain warranty.
This code has been associated with throttle body issues in vehicles with electronic throttle control systems.
Moderate – The vehicle can still be driven, but should be repaired soon to avoid further issues.
Driving in limp mode can be dangerous if not addressed promptly. Ensure repairs are done by a qualified technician.
• Engine running
• Vehicle in drive
The throttle body is located between the air filter and the intake manifold, typically on the top of the engine.
Q: Can I drive my car with this code?
A: Yes, but only for a short distance and at reduced speeds. It's best to get it fixed soon.
Q: What happens if I ignore this code?
A: Ignoring the code can lead to reduced performance and potentially more serious engine damage.
